Attention:
Starting from March 15, 2024, authorization via Basic Auth will be discontinued for the users with 2-Factor Authentication enabled.
For users:
With 2-Factor Authentication disabled for their accounts, we will continue to support Basic Authentication till the end of 2024. We highly recommend to enable 2FA to improve the user security.
With 2-Factor Authentication enabled on their accounts, we recommend requesting token authorization through the Token Manager in the Data Center Designer (DCD). The Token Manager allows users to create, list, and delete tokens based on the defined Time To Live (TTL). For more information, see Authentication token attributes. This transition ensures a secure and hassle-free authorization process for enhanced account security.
User accounts can authenticate to IONOS' APIs and SDKs only by generating authentication tokens via API/SDK Authentication Token Manager in the DCD if they:
have started the process of configuring 2FA on their account.
have completed the 2FA process on their account.
have a 2FA process obligated by the contract owner or administrator.
For more information, see Manage Authentication Tokens.
This change affects the other API actions in the following ways:
API actions such as Create new tokens, Delete tokens by criteria, Delete tokens will not be allowed.
Token generation via IonosCTL will not be allowed.
Note:
IONOS' APIs and SDKs support users to authenticate using the Basic Authentication support for non-2FA enabled and forced accounts, which will be available till this year's end.
For 2FA enabled and forced users, once the TTL expires, the tokens cannot be refreshed automatically. You need to generate a new authentication token via DCD.
Effective March 15, 2024, the Basic Authentication will not be supported for user accounts with 2FA enabled or forced, and only tokens generated from the Token Manager authenticate users to use the IONOS' APIs and SDKs. This update to APIs and SDKs authentication methods and token management is aimed at enhancing user security.
The new API/SDK Authentication Token Manager is available from February 1, 2024. For more information, see Manage Authentication Tokens.
Impacted users are encouraged to try out generating authentication tokens via API/SDK Authentication Token Manager and familiarize themselves with the new authorization method and token generation. This transition ensures a more secure and hassle-free user experience.
You are encouraged to activate 2FA to ensure secure access to your infrastructure. The APIs/ SDKs will support account security by working with tokens that can only be retrieved from the Authentication Token Manager.
All user accounts with currently 2FA enabled or forced are impacted by the Basic Authentication deprecation. New users and existing users opting for the 2FA going forward will also be impacted by this change.
The significant changes to IONOS APIs and SDKs authentication methods and token management require impacted users with 2FA enabled or forced to take the following mandatory actions:
To get started with generating authorization tokens using the API/SDK Authentication Token Manager that is available in the DCD starting February 1, 2024.
Effective March 15, 2024, only these tokens let users authenticate and use the IONOS' APIs and SDKs. The Token Manager allows you to create, list, and delete tokens. For more information, see Generate authentication token.
The following are a few FAQs to provide insights into the Basic Authentication Deprecation notice and its impact on user accounts with 2-Factor Authentication (2FA) enabled or 2FA forced.
The Basic Authentication Deprecation notice is a notification that significant changes are being made to IONOS APIs and SDKs authentication methods. Starting from February 1, 2024, the newly introduced token management feature will generate authentication tokens from the DCD, and the Basic Authentication function will be disabled for all 2FA-enabled or 2FA-forced users effective March 15, 2024.
The 2FA is enabled or forced on user accounts to enforce improved security while accessing IONOS DCD, APIs an SDKs. Hence, when the 2FA is enabled, access to IONOS' APIs and SDKs is allowed only through an authentication token, and Basic Authentication is deprecated.
After March 15, 2024, users with 2FA enabled or forced will undergo the following changes:
The existing tokens created via the Auth API will not be supported anymore.
Authentication to IONOS' APIs and SDKs is only allowed by the Authorization token that is generated from the Token Manager in the DCD.
Requesting authorization via Basic Authentication across IONOS' APIs and SDKs will not be supported by the end of 2024.
To improve user security, use the Token Manager to Generate authentication token.
Token generation via IonosCTL will not be allowed.
No, users without 2FA enabled or forced are not impacted by the Basic Authentication deprecation. Such users can continue to use Basic Authentication to access IONOS' APIs and SDKs. However, it is recommended to use 2FA for improved user security and use the Token Manager to generate authentication tokens.
To continue using IONOS' APIs and SDKs, you must request authorization through tokens that can be generated from the new Token Manager in the DCD, available from February 1, 2024. For more information, see Manage Authentication Tokens .
Using the API/SDK Authentication Token Manager, you can generate new tokens, list all tokens, and delete tokens. A new token is valid for its defined Time To Live (TTL) duration. Using these tokens, 2FA enabled or forced user accounts can authenticate to use IONOS' APIs and SDKs.
In the DCD, go to Management > Token Management. In the API/SDK Authentication Token Manager, use the Generate Token option to create a token.
You can continue using Basic Authentication till the end of 2024. However, a grace period is not possible for the users with 2FA enabled. The new token management is available effective February 1, 2024, and to continue using IONOS APIs and SDKs, you must transition to the new token management by March 15, 2024. If you do not take action by this date, you will no longer be able to access IONOS' APIs and SDKs.
Currently, the token generated from the Token Manager in the DCD is valid for a maximum of one year. There is no provision for extending this duration. You will need to renew your tokens as needed.
This change primarily applies to 2FA enabled or forced user accounts across IONOS' APIs and SDKs that were using Basic Authentication for authorization. Other services and APIs continue to have their authentication methods and policies.
No, after the deprecation date (March 15, 2024), Basic Authentication tokens will no longer be valid for authorization for 2FA-enabled and forced users. You must switch to using tokens provided by the Token Manager.
This change enhances user security by moving away from Basic Authentication, which is considered less secure, and by providing a more streamlined and user-friendly token management system for APIs and SDKs access. It helps protect user data and accounts.
For more information or assistance with this transition, you can contact IONOS Cloud Support or see Deprecation of Basic Authentication documentation.
For the Token Management APIs, if you have 2-Factor Authentication configured, then you are no longer allowed to create or delete tokens using this API. You can use the Token Manager in the Data Center Designer (DCD) to create or delete the tokens.
Cubes are virtual private service instances with shared resources. Refer to our user guides, reference documentation, and FAQs to support your hosting needs.
Prerequisites: Prior to setting up a virtual machine, make sure you have the appropriate privileges. Only contract owners, administrators, or users with the Create Data Center privilege can set up a VDC. Other user types have read-only access and can't provision changes.
This tutorial guides you through creating and managing Users, User Groups, and Resources in the Virtual Data Center (VDC).
Prerequisites: Make sure you have the appropriate privileges. Only contract administrators and owners can manage users within a VDC.
A new VDC in the Data Center Designer (DCD) is manageable by contract owners. To assign resource management capabilities to other members in VDC, you can add users and groups and grant them appropriate privileges to work with the data center resources.
The User Manager lets you create new users, add them to user groups, and assign privileges to each group. Privileges either limit or increase your access based on the user role. The User Manager lets you control user access to specific areas of your VDC.
In the DCD, go to Menu > Management > Users & Groups.
Select + Create in the Users tab.
Enter the user's First Name, Last Name, Email, and Password.
Note: The email address of the new user must be unique.
Select Create to confirm.
Result: A user is successfully created and listed in the Users list.
The creation of groups is useful when you need to assign specific duties to the members of a group. You can create a group and add members to this group. You can then assign privileges to the entire group.
In the Groups tab, select + Create.
Enter a Group Name.
Select Create to confirm.
Result: The group is now created and visible in the Groups list. You can now assign permissions, users, and resources to your group.
In the Groups tab, select a group from the Groups list.
In the Privileges tab, select checkboxes next to the privilege name.
Note: You do not need to save your selections. This action automatically grants or removes privileges.
Result: The group has the required privileges now.
Note: To remove the privileges for a group, clear the checkbox next to the privilege name.
Users are added to your new group on an individual basis. Once you have created a new member, you must assign them to the group.
In the Groups tab, select the required group.
In the Members tab, add users from the + Add User drop-down list.
Result: The users are now assigned to the group. These users have privileges and access rights to the resources corresponding to their group.
When assigning a user to a group, whether you are a contract owner or an administrator, you can:
Create a new user within DCD.
Note: Administrators do not need to be managed in groups, as they automatically have access to all resources associated with the contract.
In the Resources tab, select a resource from the drop-down list.
In the Visible to Groups tab, click + Add Group.
Select a group from the drop-down list.
Result: This group can now access the allocated resource.

Result: This user is now removed from the group.
This tutorial guides you through generating and managing authentication tokens in the Data Center Designer (DCD).
Note: The API/SDK Authentication Token Manager can be used by any user but is mandatory for 2FA enabled and forced accounts.
In the DCD, you can now generate the authentication token to securely access IONOS Cloud APIs and SDKs by using the API/SDK Authentication Token Manager. Along with improved user security, the Token Manager offers a seamless user experience to generate tokens in a simplified way and use the token several times to access the APIs and SDKs. You can generate up to 100 authentication tokens and use any of these token values for authorizing access to APIs and SDKs.
To create a secure authentication token for authorizing to use APIs and SDKs, follow these steps:
In the DCD, go to Menu > Management > Token Management.
In the API/SDK Authentication Token Manager, select Generate Token.
Copy the Token ID and Close the token-generated window.
Warning: You must save the token value for future uses. You will not be able to see the token value again due to security reasons.
Note: You can download the token value as a text file for future uses by selecting the Download option next to the Token Value.
Result: An authentication token is generated and listed in the API/SDK Authentication Token Manager screen.
Each token has a Time To Live (TTL), which is the duration for which a token is valid before it expires and becomes inactive. Select a TTL value from the drop-down list. The following are the possible values:
1 Hour
4 Hours
1 Day
7 Days
30 Days
60 Days
90 Days

When creating storages based on IONOS Linux images, you can inject SSH keys into your VM. This lets you access your VM safely and allows for secure communication. SSH keys that you intend to use more often can be saved in the DCD's SSH Key Manager.
Default SSH keys: SSH keys that you intend to use often and mark them as such in the SSH Key Manager. Default SSH keys are preselected when you configure storage devices. You can specify which SSH keys are actually to be used before provisioning and deselecting the preselected standard keys in favor of another SSH key.
Ad-hoc SSH keys: SSH keys that you only use once and don't intend to save in the SSH Key Manager for later re-use.
SSH keys can be generated and used on macOS or Linux if both OpenSSH and the ssh-keygen command-line tools are installed. OpenSSH is a collection of tools for establishing SSH connections to remote servers, while ssh-keygen is a utility for generating SSH keys.
Manually generate SSH keys when working with OpenSSH via the Terminal application by following the steps below.
1. Enter the following command below into the Terminal window and press ENTER.
The key generation process is initiated by the command above. When you run this command, the ssh-keygen utility prompts you for a location to save the key.
2. Accept the default location by pressing the ENTER key, or enter the path to the file where you want to save the key /home/username/.ssh/id_rsa
.
If you have previously generated a key pair, you may see the following prompt below. If you choose to overwrite the key, you will no longer authenticate with the previous key that was generated.
3. Enter the passphrase that will be used to encrypt the private key file on the disk. You can also press ENTER to accept the default (no passphrase). However, we recommend that you use a passphrase.
4. Enter your passphrase once more.
After you confirm the passphrase, the public and private keys are generated and saved in the specified location. Thus, the confirmation will look like this:
The public key is saved to the file id_rsa.pub
which will be the key you upload to your DCD account. Your private key is saved to the id_rsa
file in the .ssh
directory and is used to verify that the public key you use belongs to the same DCD account.
You can copy the public key to your clipboard by running the following command:
In the SSH Key Manager of the DCD, you can save and manage up to 100 public SSH keys for the setup of SSH accesses. This saves you from having to repeatedly copy and paste the public part of an SSH key from an external source.
1. To open the SSH Key Manager, go to Menu > MANAGER resources > SSH Key Manager.
2. In the SSH Key Manager, select + Add Key.
3. Enter a Name and click Add.
4. Copy and paste the public key to the SSH key field. Alternatively, you may upload it via Select key file. Please ensure the SSH keys you enter are valid. The DCD does not validate syntax or format.
5. (Optional) Activate the Default checkbox to have the SSH key automatically pre-selected when SSH access is configured.
6. Click Save to store the key.
The SSH key is stored in the SSH Key Manager and can be used for the configuration of SSH accesses.
To delete an existing SSH key, select the SSH key from the list and click Delete Key.
The SSH key is removed from the SSH Key Manager.
You can connect to your virtual instance via OpenSSH. Still, you will need the terminal application, which varies depending on your operating system. For:
Linux: Search Terminal or press CTRL+ALT+T
macOS: Search Terminal
Windows: Search Bash. If you don’t have Bash installed, use PuTTY instead.
The steps below will show you how to connect to your VM.
1. Open the Terminal application and enter the SSH connection command below. After the @

SSH keys can be generated and used on macOS or Linux if both OpenSSH and the ssh-keygen command-line tools are installed. OpenSSH is a collection of tools for establishing SSH connections to remote servers, while ssh-keygen is a utility for generating SSH keys.
An SSH key is composed of two files. The first is the private key, which should never be shared. The other is a public key that enables you to access your provisioned Cubes. When you generate the keys, you will use ssh-keygen to store them in a secure location so that you can connect to your instances without encountering the login prompt.
Manually generate SSH keys when working with OpenSSH via the Terminal application by following the steps below.
Enter the following command below into the Terminal window and press ENTER.
The key generation process is initiated by the command above. When you run this command, the ssh-keygen utility prompts you for a location to save the key.
Accept the default location by pressing the ENTER key, or enter the path to the file where you want to save the key /home/username/.ssh/id_rsa
.
If you have previously generated a key pair, you may see the following prompt below. If you choose to overwrite the key, you will no longer authenticate with the previous key that was generated.
Enter the passphrase that will be used to encrypt the private key file on the disk. You can also press ENTER to accept the default (no passphrase). However, we recommend that you use a passphrase.
Enter your passphrase once more.
After you confirm the passphrase, the public and private keys are generated and saved in the specified location. Thus, the confirmation will look like this:
The public key is saved to the fileid_rsa.pub
which will be the key you upload to your DCD account. Your private key is saved to the id_rsa
file in the .ssh
directory and is used to verify that the public key you use belongs to the same DCD account.
You can copy the public key to your clipboard by running the following command:
In addition to the SSH Keys stored in the SSH Key Manager, the IONOS Cubes SSH key concept includes:
Default keys
Ad-hoc SSH Keys.
Default keys are SSH keys that you intend to use frequently and have marked as such in the SSH Key Manager. When you configure storage devices, the default SSH keys are pre-selected. You can, however, specify which SSH keys are to be used before provisioning and deselect the preselected standard keys in favor of another SSH key.
Ad-hoc SSH keys, on the other hand, are SSH keys that you only use once and do not intend to save in the SSH Key Manager for future use.
The DCD's SSH Key Manager allows you to save and manage up to 100 public SSH keys for SSH access setup. This saves you from having to copy and paste the public part of an SSH key from an external source multiple times.
Log in to your DCD account after copying the SSH key to the clipboard (Link).
1. Open the SSH Key Manager: Menu > Management > SSH Keys
2. Select the + Add Key in the top left corner.
3. Paste the SSH key from the clipboard into the SSH Key field. If you have saved your SSH Key in a file, you can upload it by selecting the Choose file button in the Select Key file field.
Make sure the SSH keys you enter are valid. The DCD does not validate the syntax or format of the keys.
Optional: Select the Default checkbox to have the SSH key pre-selected when configuring SSH access.
4. Click Save to save the key. The SSH key has now been saved in the SSH Key Manager and is visible in the SSH Key Manager's table of keys.
You can connect to your Cubes instance via OpenSSH. Still, you will need the terminal application, which varies depending on your operating system. For:
Linux: Search Terminal or press CTRL+ALT+T
macOS: Search Terminal
Windows: Search Bash. If you don’t have Bash installed, use PuTTY instead.
The steps below will show you how to connect to your Cubes.
Open the Terminal application and enter the SSH connection command below. After the @
, add the IP address of your Cubes instance. Then press ENTER.
When you log in for the first time, the server isn't recognized on your local machine, so you'll be asked if you're sure you want to keep connecting. You can type yes and then press ENTER.
Authentication is the next step in the connection process. If you've added the SSH keys, you'll be able to connect to the Cubes immediately or after entering your key pair's passphrase.
If you haven't already added SSH keys, you'll be asked for your password:
Nothing is displayed in the terminal when you enter your password, making it easier to paste in the initial password. Pasting into text-based terminals is different from other desktop applications. It is also different from one window manager to another:
For Linux Gnome Terminal, use CTRL+SHIFT+V.
For macOS, use the SHIFT-CMD-V or a middle mouse button.
For Bash on Windows, right-click on the window bar, choose Edit, then Paste. You can also right-click to paste if you enable QuickEdit mode.
Once you’ve entered the password, press ENTER.
If the SSH key is configured correctly, this will log you into the Cubes.
Cloud-init is a software package that automates the initialization of servers during system boot. When you deploy a new Linux server from an image, cloud-init gives you the option to set default user data. User data must be written in shell scripts or cloud-config directives using YAML syntax. This method is highly compatible across platforms and fully secure.
Compatibility: This service is supported on all public IONOS Cloud Linux distributions (Debian, CentOS, and Ubuntu). You may submit user data through the DCD or via Cloud API. Existing cloud-init configurations from other providers are compatible with IONOS Cloud.
Limitations: Cloud-init is available on all public images supplied by IONOS Cloud. If you wish to use your own Linux image, please make sure that it is cloud-init supported first. Otherwise, there is no guarantee that the package will function as intended. Windows images are currently out of scope; adding them may be considered at a later stage.
Provisioning: Cloud-init can only be set at initial provisioning. It cannot be applied to instances that have already been provisioned. Settings can't be changed once provisioned.
Laptops: When using a laptop, please scroll down the properties panel, as additional fields are not immediately visible on a small screen.
This tutorial demonstrates the use of cloud-config and user-data scripts. However, the cloud-init package supports a variety of formats.
1. In the DCD, create a new virtual instance and attach any storage device to it.
2. Ensure the storage device is selected. Its Inspector pane should be visible on the right.
3. When choosing the Image, you may either use your own or pick one that is supplied by IONOS.
For IONOS supplied images, select No image selected > IONOS Images.
Alternatively, for private images select No image selected > Own Images.
4. Once you choose an image, additional fields will appear in the Inspector pane.
5. A Root password is required for Remote Console access. You may change it later.
6. SSH keys are optional. You may upload a new key or use an existing file. SSH keys can also be injected as user data utilizing cloud-init.
7. You may add a specific key to the Ad-hoc SSH Key field.
8. Under Cloud-init user data, select No configuration and a window will appear.
9. Input your cloud-init data. Either use a bash script or a cloud-config file with YAML syntax. Sample scripts are provided below.
10. To complete setup, return to the Inspector and click Provision Changes. Cloud-init automatically runs at boot, applying the changes requested.
When the DCD returns the message that provisioning has been successfully completed this means the infrastructure is virtually set up. However, bootstrapping, which includes the execution of cloud-init data, may take additional time. This execution time is not included in the success message. Please allow extra time for the tasks to complete before testing.
Using shell scripts is an easy way to bootstrap a server. In the example script below, the code creates and configures our CentOS web server.
Allow enough time for the instance to launch and run the commands in your script, and then check to see that your script has completed the tasks that you intended.
The above example will install a web server and rewrite the default index.html file. To test if cloud-init bootstrapped your VM successfully, you can open the corresponding IP address in your browser. You should be greeted with a “Hello World” message from your web server.
Cloud-init images can also be bootstrapped using cloud-config directives. The cloud-init website outlines all supported modules and gives examples of basic directives.
The following script is an example of how to create a swap partition with second block storage, using a YAML script:
The following script is an example of how to resize your file system according to the chosen size of the block storage. It will also create a user with an SSH key, using a cloud-config YAML script:
The cloud-init output log file (/var/log/cloud-init-output.log) captures console output. Depending on the default configuration for logging, a second log file exists under /var/log/cloud-init.log. **** This provides a comprehensive record based on user data.
Cloud API provides enhanced convenience if you want to automate the provisioning and configuration of cloud instances. Cloud-init is configured on the volume resource in Cloud API V6 (or later). Please find the link to the documentation below:
Name: userData
Type: string
Description: The cloud-init configuration for the volume as base64 encoded string. The property is immutable and is only allowed to be set on a new volume creation. It is mandatory to provide either public image
or imageAlias
that has cloud-init compatibility in conjunction with this property.
For a long time, the duopoly of virtual private servers (VPS) and dedicated cloud servers dominated virtualized computing environments.
Enter Cubes — virtual private service instances — the next generation of IaaS. Developed by IONOS Cloud, Cubes are ideal for specific workloads that do not require high compute performance from all resources at all times — development and testing environments, website hosting, simple web applications, and so on.
While based on shared resources, the Cubes can rival physical servers through a platform design that can redistribute available performance capacities among individual instances. At the same time, reduced operational complexity and highly optimized resource utilization translate into lower operating costs.
Cubes instances can be used together with all enterprise-grade features, resources, and services, offered by IONOS Cloud.
Affordable, quickly available, and with everything you need — have your Cubes up and running in minutes in the IONOS Cloud.
You can enable IPv6 on Cubes when you create them or after you create them.
You can set up IPv6 to improve the network connectivity for your virtualized environment. By setting up IPv6 for your Cubes, you can ensure that they are accessible to IPv6-enabled networks and clients.
Prerequisites: Prior to enabling IPv6, make sure you have the appropriate privileges. New VDC can be created by the contract owners, admins, or users with create VDC privilege. The number of bits in the fixed address is the prefix length. For Data Center IPv6 CIDR, the prefix length is /56.
To enable IPv6 for Cubes, connect the server to an IPv6-enabled LAN. Select the Network option on the right pane and fill in the following fields:
Name: It is recommended to enter a unique name for this Network Interface Controller (NIC).
MAC: This field is automatically populated.
LAN: Select an IPv6 enabled Local Area Network (LAN).
Firewall: Specify whether you want to enable or disable the firewall. For enabling the firewall, choose Ingress to create flow logs for incoming traffic, Egress for outgoing traffic, or Bidirectional to create flow logs for all traffic.
Flow Log: Select + to add a new flow log. Enter name, direction, action, target S3 bucket, and select + Flow Log to complete the configuration of the flow log. It becomes applied once you provision your changes.
IPv4 Configuration: This field is automatically populated. If Dynamic Host Configuration Protocol (DHCP) is enabled, the Internet Protocol version 4 (IPv4) address is dynamic, meaning it can change while the Dedicated Core Server is operational or in the case of a restart. Add additional public IP addresses in Add IP. It is an optional field.
IPv6 Configuration: You can populate a NIC IPv6 CIDR block with prefix length /80 or allow it to be automatically assigned from the VDCs allocated range, as seen in the screenshot below. In order to use "floating" or virtual IPs, you can assign additional IPs to a NIC by selecting them from the drop-down list in Add IP.
Note:
IPv6 CIDR assigned to LANs(/64) and NICs(/80 and /128) must be unique.
You can create a maximum of 256 IPv6-enabled LANs per VDC.

Base64
If user-data is base64-encoded, cloud-init determines if it can understand the decoded data as one of the supported types. If it understands the decoded data, it decodes the data and handles it appropriately. If not, it returns the base64 data intact.
User-Data Script
Begins with #!
or Content-Type: text/x-shellscript
.
The script is run by /etc/init.d/cloud-init-user-scripts during the first boot cycle. This occurs late in the boot process (after the initial configuration actions are performed).
Include File
Begins with #include
or Content-Type: text/x-include-url
.
The file contains a list of URLs, one per line. Each of the URLs is read, and their content is passed through this same set of rules. The content read from the URL can be MIME-multi-part or plaintext.
Cloud Config data
Begins with #cloud-config
or Content-Type: text/cloud-config
.
For a commented example of supported configuration formats, see the examples.
Upstart Job
Begins with #upstart-job
or Content-Type: text/upstart-job
.
This content is stored in a file in /etc/init
, and upstart consumes the content as per other upstart jobs.
Cloud Boothook
Begins with #cloud-boothook
or Content-Type: text/cloud-boothook
.
This content is boothook
data. It is stored in a file under /var/lib/cloud
and then runs immediately.
This is the earliest hook
available. There is no mechanism provided for running it only one time. The boothook must take care of this itself. It is provided with the instance ID in the environment variable INSTANCE_ID.
Use this variable to provide a once-per-instance set of boothook data

Assigning different Availability Zones ensures that servers or storage devices reside on separate physical resources at IONOS.
For example, a server or a storage device assigned to Availability Zone 1 resides on a different resource than a server or storage device assigned to Availability Zone 2.
You have the following Availability Zone options:
Zone 1
Zone 2
A - Auto (default; our system automatically assigns an Availability Zone upon provisioning)
After uploading, you can define the properties of your images before applying them to new storage volumes. The settings must be supported by the image, otherwise, they will not work as expected. After provisioning, you can change the settings directly on the storage device, which will require a restart of the server.
For IONOS images, the supported properties are already preset. Without restarting the Dedicated Core Server, its resources can be scaled as follows:
Upscaling: CPU, RAM, NICs, storage volumes
Downscaling: NICs, storage volumes
Scaling up is the increase or speed up of a component to handle a larger load. The goal is to increase the number of resources that support an application to achieve or maintain accurate performance. Scaling down means reducing system resources, irrespective of whether you have used the scaling-up approach. Without restarting the Dedicated Core Server, only upscaling is possible.
CPU Types: Dedicated Core Server configurations are subject to the following limitations, by CPU type:
AMD CPU
Intel® CPU
A single Intel® physical core with Hyper-Threading Technology is exposed to the operating system of your Dedicated Core Server as two distinct "logical cores", which process separate threads.
RAM Sizes: Because the working memory (RAM) size cannot be processed during the initial configuration, newly provisioned servers with more than 8 GB of RAM may not start successfully when created from IONOS Windows images.
Live Vertical Scaling: Linux supports the entire scope of IONOS Live Vertical Scaling, whereas Windows is limited to CPU scaling. Furthermore, it is not possible to use LVS to reduce storage size after provisioning.
Assigning different Availability Zones ensures that vCPU Servers or storage devices reside on separate physical resources at IONOS. This helps ensure high availability and fault tolerance for your applications, as well as providing low-latency connections to your target audience.
For example, a vCPU Server or a storage device assigned to Availability Zone 1 resides on a different resource than a vCPU Server or storage device assigned to Availability Zone 2.
You have the following Availability Zone options:
Zone 1
Zone 2
A - Auto (default; our system automatically assigns an Availability Zone upon provisioning)
After uploading, you can define the properties of your images before applying them to new storage volumes. The settings must be supported by the image, otherwise, they will not work as expected. After provisioning, you can change the settings directly on the storage device, which will require a restart of the vCPU Server.
For IONOS images, the supported properties are already preset. Without restarting the vCPU Server, its resources can be scaled as follows:

Scaling up is the increase or speed up of a component to handle a larger load. The goal is to increase the number of resources that support an application to achieve or maintain accurate performance. Scaling down means reducing system resources, whether or not you have used the scaling-up approach. Without restarting the vCPU Server, only Upscaling is possible.
vCPU Server provides the following features:
Flexible Resource Allocation provides you with presets, which are recommended vCPU-to-RAM configurations for your virtual machines. Furthermore, this option empowers you to add or remove compute resources flexibly to meet your specific needs.
The Robust Compute Engine platform supports the vCPU servers, ensuring seamless integration. Additionally, the features offered by the Compute Engine platform remain accessible for utilization with vCPU servers
Virtualization Technology enables efficient and secure isolation between different VMs, ensuring the performance of one VM does not impact the others.
Reliable Performance and computing capabilities make it suitable for a wide range of applications. The underlying infrastructure is optimized to provide reliable CPU performance, ensuring your applications run smoothly.
Easy Management via the intuitive Data Center Designer. You can easily create, modify, and delete vCPU Servers, monitor their usage, and adjust the resources according to your needs.
vCPU Server provides the following benefits:
Cost-Effective: vCPU Server helps reduce costs when compared to major hyperscalers with similar resource configurations. This makes it an ideal choice for small to medium-sized businesses or individuals with budget constraints.
Scalability:** With the IONOS vCPU Server, you have the flexibility to scale your computing resources up or down based on your requirements. This ensures that you can meet the demands of your applications without overprovisioning or paying for unused resources.
Reliability and Availability: IONOS's cloud infrastructure ensures high availability and reliability. By distributing resources across multiple physical servers, IONOS minimizes the impact of hardware failures, providing a stable and resilient environment for your applications.
Easy Setup: Setting up the IONOS vCPU Server is straightforward. The IONOS DCD and Cloud API offer controls for provisioning and configuring vCPU Servers, allowing you to get up and running quickly.
This section lists the limitations of vCPU Servers:
CPU Family of a vCPU Server cannot be chosen at the time of creation and cannot be changed later. vCPU Server configurations are subject to the following:
RAM Sizes: Because the working memory (RAM) size cannot be processed during the initial configuration, a newly provisioned vCPU Server with more than 8 GB of RAM may not start successfully when created from the IONOS Windows images.
Live Vertical Scaling: Linux supports the entire scope of IONOS Live Vertical Scaling, whereas Windows is limited to CPU scaling. Furthermore, it is not possible to use LVS to reduce storage size after provisioning.
Prerequisites: Prior to setting up a virtual machine, please make sure you have the appropriate privileges. Only contract owners, administrators, or users with the Create Data Center privilege can set up a . Other user types have read-only access and can't provision changes.

You can pass the user data in various formats to the IONOS cloud-init at launch time. Typically, this happens as a template, a parameter in the CLI, etc. This method is highly compatible across platforms and fully secure.
Limitations: Cloud-init is available on all public Linux images supplied by IONOS Cloud. If you wish to use your own Linux image, please make sure that it is cloud-init supported first. Otherwise, there is no guarantee that the package will function as intended. Windows images are currently out of scope; adding them may be considered at a later stage.
Provisioning: Cloud-init can only be set at initial provisioning. It cannot be applied to instances that have already been provisioned. Settings cannot be changed once provisioned.
Laptops: When using a laptop, scroll down the properties panel of the block storage volume that you want to create and configure, as additional fields are not immediately visible on a small screen. Clout-Init may only become visible when an supported image has been selected.
The following table demonstrates the use of cloud-config and user-data scripts. However, the cloud-init package supports a variety of formats.
Log in to the DCD with your username and password.
In the Workspace, create a new virtual instance and attach any storage device to it.
Select the storage device and from the Inspector pane associate an Image with it.
To associate a private image, select Own Images from the drop-down list.
To associate a public image, select IONOS Images from the drop-down list. Once you choose an image, additional fields will appear in the Inspector pane.
Enter a Password. It is required for Remote Console access. You may change it later.
(Optional) Upload a new SSH key or use an existing file. SSH Keys can also be injected as user data utilizing cloud-init.
(Optional) Add a specific key to the Ad-hoc SSH Key field.
Select No configuration for Cloud-Init user data and the Cloud-Init User Data window appears.
To complete setup, return to the Inspector pane and click Provision Changes.
Using shell scripts is an easy way to bootstrap a server. The code creates, installs, and configures our CentOS web server in the following example. It also rewrites the default index.html file.
Note: Allow enough time for the instance to launch and run the commands in your script, and later verify if your script has completed the tasks you intended.
The following script is an example of how to create a swap partition with second block storage using a YAML script:
The following script is an example of how to resize your file system according to the chosen size of the block storage. It will also create a user with an SSH key using a cloud-config YAML script:
The cloud-init output log file (/var/log/cloud-init-output.log
) captures console output. Depending on the default configuration for logging, a second log file exists within /var/log/cloud-init.log
. This provides a comprehensive record based on the user data.
The cloud API offers increased convenience if you want to automate the provisioning and configuration of cloud instances. Enter the following details:

The Remote Console is used to connect to a server when, for example, no SSH is available. You must have the root or administrator password for this type of log-in to the server.
Prerequisites: Make sure you have the appropriate permissions. Only contract owners, administrators, or users with access rights to the data center can connect to a server. Other user types have read-only access and can't provision changes.
Start the Remote Console from the server.
Open the data center containing the required server.
In the Workspace, select the server.
In the Inspector, choose Remote Console or select Remote Console from the context menu of the server.
Start the Remote Console from the Start Center (contract owners and administrators only).
Open the Start Center: Menu Bar > Data Center Designer > Open Start Center
Open the Details of the required data center. A list of servers in this data center is displayed.
Select the server and click Open Remote Console.
Remote Console version matching your browser opens; you can now log on to the server with root or administrator password.
Use the Send Key Combo button on the top right of the Remote Console window to send shortcut key combinations (such as CTRL+ALT+DEL).
Launch this Remote Console window again with one click by bookmarking its URL address in your browser.
For security reasons, once your session is over, always close the browser used to connect to VM with this bookmark.
When creating storages based on IONOS Linux images, you can insert SSH keys into your VM. This lets you access your VM safely and allows for secure communication. SSH keys that you intend to use more often can be saved in the DCD's SSH Key Manager.
Note: IONOS Windows images do not support SSH key injection.
Default SSH keys: SSH keys that you intend to use often and mark them as such in the SSH Key Manager. Default SSH keys are preselected when you configure storage devices. You can specify which SSH keys are actually to be used before provisioning and deselecting the preselected standard keys in favor of another SSH key.
Ad-hoc SSH keys: SSH keys that you only use once and don't intend to save in the SSH Key Manager for later re-use.
SSH keys can be generated and used on macOS or Linux if both OpenSSH and the ssh-keygen command-line tools are installed. OpenSSH is a collection of tools for establishing SSH connections to remote servers, while ssh-keygen is a utility for generating SSH keys.
Manually generate SSH keys when working with OpenSSH via the Terminal application by following the steps below.
1. Enter the following command below into the Terminal window and press ENTER.
The key generation process is initiated by the command above. When you run this command, the ssh-keygen utility prompts you for a location to save the key.
2. Accept the default location by pressing the ENTER key, or enter the path to the file where you want to save the key /home/username/.ssh/id_rsa
.
If you have previously generated a key pair, you may see the following prompt below. If you choose to overwrite the key, you will no longer authenticate with the previous key that was generated.
3. Enter the passphrase that will be used to encrypt the private key file on the disk. You can also press ENTER to accept the default (no passphrase). However, we recommend that you use a passphrase.
4. Enter your passphrase once more.
After you confirm the passphrase, the public and private keys are generated and saved in the specified location. Thus, the confirmation will look like this:
The public key is saved to the file id_rsa.pub
which will be the key you upload to your DCD account. Your private key is saved to the id_rsa
file in the .ssh
directory and is used to verify that the public key you use belongs to the same DCD account.
You can copy the public key to your clipboard by running the following command:
In the SSH Key Manager of the DCD, you can save and manage up to 100 public SSH keys for the setup of SSH accesses. This saves you from having to repeatedly copy and paste the public part of an SSH key from an external source.
1. To open the SSH Key Manager, go to Menu > MANAGER resources > SSH Key Manager.
2. In the SSH Key Manager, select + Add Key.
3. Enter a Name and click Add.
4. Copy and paste the public key to the SSH key field. Alternatively, you may upload it via Select key file. Please ensure the SSH keys you enter are valid. The DCD does not validate syntax or format.
5. (Optional) Activate the Default checkbox to have the SSH key automatically pre-selected when SSH access is configured.
6. Click Save to store the key.
The SSH key is stored in the SSH Key Manager and can be used for the configuration of SSH accesses.
To delete an existing SSH key, select the SSH key from the list and click Delete Key.
The SSH key is removed from the SSH Key Manager.
You can connect to your virtual instance via OpenSSH. Still, you will need the terminal application, which varies depending on your operating system. For:
Linux: Search Terminal or press CTRL+ALT+T
macOS: Search Terminal
Windows: Search Bash. If you don’t have Bash installed, use PuTTY instead.
The steps below will show you how to connect to your VM.
1. Open the Terminal application and enter the SSH connection command below. After the @
, add the IP address of your VM instance. Then press ENTER.
Note: When you log in for the first time, the server isn't recognized on your local machine, so you'll be asked if you're sure you want to keep connecting. You can type yes and then press ENTER.
2. Authentication is the next step in the connection process. If you've added the SSH keys, you'll be able to connect to the VM immediately or after entering your key pair's passphrase.
If you haven't already added SSH keys, you'll be asked for your password:
3. Once you’ve entered the password, press ENTER.
If the SSH key is configured correctly, this will log you into VM.

This is solely for informational purposes and does not require anything from you. IONOS has renamed Virtual Server(s) to Dedicated Core Server(s). This change does not impact the functionality of the product in any manner. As a result, the documentation portal now reflects the product name changes. For more information, see Product Renaming FAQs.
The user who creates the Dedicated Core server has full root or administrator access rights. A server, once provisioned, retains all its settings (resources, drive allocation, password, etc.), even after a restart at the operating system level. The server will only be removed from your Virtual Data Center once you delete a server in the DCD. For more information, see Dedicated Core Servers.
Prerequisites: Make sure you have the appropriate privileges. Only contract administrators, owners, or users with the Create Data Center privilege can set up a VDC. Other user types have read-only access and can't provision changes.
1. Drag the Dedicated Core server element from the Palette onto the Workspace.
The created Dedicated Core server is automatically highlighted in turquoise. The Inspector pane allows you to configure the properties of this individual server instance.
2. In the Inspector pane on the right, configure your server in the Settings tab.
Name: Choose a name unique to this VDC.
Availability Zone: The zone where you wish to physically host the server. Choosing A - Auto selects a zone automatically. This setting can be changed after provisioning.
CPU Architecture: Choose between AMD or Intel cores. You can later change the CPU type for a Dedicated Core server that is already running, though you will have to restart it first.
Cores: Specify the number of CPU cores. You may change these after provisioning. Note that there are configuration limits.
RAM: Specify RAM size; you may choose any size between 0.25 GB to 240 GB in steps of 0.25 GB. This setting can be increased after provisioning.
SSH Keys: Select premade SSH Key. You must first have a key stored in the SSH Key Manager. Learn how to create and add SSH Keys.
Ad-hoc Key: Copy and paste the public part of your SSH key into this field.
Drag a storage element (HDD or SSD) from the Palette onto a Dedicated Core server in the Workspace to connect them together. The highlighted VM will expand with a storage section.
Click the Unnamed HDD Storage to highlight the storage section. Now you can see new options in the Inspector pane on the right.
Storage type cannot be changed after provisioning.
Enter a name that is unique within your VDC.
Select a zone in which you want the storage device to be maintained. When you select A (Auto), our system assigns the optimal Zone. The Availability Zone cannot be changed after provisioning.
Specify the required storage capacity. You can increase the size after provisioning, even while the vCPU Server is running, as long as its operating system supports it. It is not possible to reduce the storage size after provisioning.
You can select one of IONOS images or snapshots, or use your own. Only images and snapshots that you have access to are available for selection. Since provisioning does not require you to specify an image, you can also create empty storage volumes.
Authentication
Set the root or administrator password for your Dedicated Core server according to the guidelines. This is recommended for both operating system types.
Select an SSH key stored in the SSH Key Manager.
Copy and paste the public part of your SSH key into this field.
Select the storage volume from which the Dedicated Core server is to boot by clicking on BOOT or Make Boot Device.
Provision your changes. The storage device is now provisioned and configured according to your settings.
Alternative Mode
When adding a storage element using the Inspector pane, select the appropriate check box in the Add Storage dialog box. If you wish to boot from the network, set this on the Dedicated Core server: Dedicated Core server in the Workspace > Inspector pane > Storage.
It is recommended to always use VirtIO to benefit from the full performance of InfiniBand. IDE is intended for troubleshooting if, for instance, the operating system has no VirtIO drivers installed. In this case, Windows usually displays a "blue screen" when booting.
After provisioning, the Live Vertical Scaling properties of the selected image are displayed. You can make changes to these properties later, which will require a reboot. You can set the properties of your uploaded images before you apply them to storage volumes in the Image Manager.
(Optional) Add and configure further storage elements.
(Optional) Make further changes to your data center.
Provision your changes. The storage device is now provisioned and configured according to your settings.
To assign an image and specify a boot device, you need to add and configure a storage element.
Click on CD-ROM to add a CD-ROM drive so that you can use ISO images to install and configure an operating system from scratch.
Set up a network by connecting the Dedicated Core server to other elements, such as an internet access element or other servers through their NICs.
Provision your changes.
The Dedicated Core server is available according to your settings.
We maintain dedicated resources available for each customer. You do not share your physical CPUs with other IONOS clients. For this reason, the servers switched off at the operating system level, still incur costs.
You should use the DCD to shut down virtual machines so that resources are completely deallocated, and no costs are incurred. Dedicated Core servers deallocated this way remain in your infrastructure while the resources are released and can then be redistributed.
This can only be done in the DCD. Shutting down a VM at the operating system level alone does not deallocate the resources or suspend the billing. Regardless of how the VM is shut down, it can only be restarted using the DCD.
A reset forces the Dedicated Core server to shut down and reboot but may result in data loss.
Stopping a VM will:
Suspend billing
Cut power to your VM
De-allocate any dynamically assigned IP address
1. Choose a Dedicated Core server. From the Settings tab in the Inspector pane, select Power > Stop.
2. In the dialog box that appears, confirm your action by selecting the appropriate checkbox and clicking Apply STOP.

4. Provision your changes. Confirm the action by entering your password.
Result: The Dedicated Core server shuts down and reboots.
1. In the Workspace, select the required Dedicated Core server and use the Inspector pane on the right.
If you want to change multiple VMs, select the data center and change the properties in the Settings tab.
In this tab, you will find an overview of all assets belonging to the selected VDC. You can change cores, RAM, server status, and storage size without having to manually update each VM in the Workspace.
2. Modify storage:
(Optional) Create a snapshot of the system for recovery in the event of problems.
3. In the Workspace, select the required Dedicated Core server and increase the CPU size.
4. Provision your changes. You must set the new size at the operating system level of your VM.
Result: The size of the CPU is adjusted in the DCD.
When you no longer need a particular Dedicated Core server, with or without the associated storage devices, in your cloud infrastructure, you can remove it with a single mouse click or via the keyboard.
To ensure that no processes are interrupted and no data is lost, we recommend you turn off the Dedicated Core server before you delete it.
1. Select the Dedicated Core server in the Workspace.
2. Right-click and open the context menu of the element. Select Delete.
2. You may also select the element icon and press the DEL key.
3. In the dialog box that appears, choose whether you also want to delete storage devices that belong to the server.
4. Provision your changes.
Result: The Dedicated Core server and its storage devices are deleted.
When you delete a Dedicated Core server and its storage devices, or the entire data center, their backups are not deleted automatically. When you delete a Backup Unit, the associated backups are also deleted.
When you no longer need the backups of deleted VMs, delete them manually from the Backup Unit Manager to avoid unnecessary costs.
A user with full root or administrator access rights can create a vCPU Server. A vCPU Server, once provisioned, retains all its settings, such as resources, drive allocation, password, etc., even after a restart at the operating system level. A vCPU Server is deleted from your Virtual Data Center (VDC) only when you delete it from the DCD. For more information, see vCPU Servers.
vCPU Servers offer flexible configurations for RAM and CPUs. You can create a vCPU Server via the DCD or the API.
Prerequisite: Make sure you have the appropriate privileges. Only contract administrators, owners, and users with the Create Data Center privilege can set up a VDC. Other user types have read-only access and cannot provision changes.
To create a new vCPU Server via the DCD, follow these steps:
1. Drag the vCPU Server element from the Palette onto the Workspace.
The created vCPU Server is automatically highlighted in turquoise. The Inspector pane allows you to configure the properties of this individual vCPU instance.
2. In the Inspector pane on the right, configure your vCPU Server in the Settings tab.
Name: Choose a name unique to this VDC.
Availability Zone: The zone where you wish to physically host the vCPU. Choosing A - Auto selects a zone automatically. This setting can be changed after provisioning.
Preset: Select an appropriate configuration from the drop-down list. The values S, M, L, XL, and XXL contain predefined vCPU-to-RAM ratios. You can always override the values to suit your needs and the Preset automatically changes to Custom when you edit the predefined ratio indicating that you are no longer using the predefined ratio.
vCPUs: Specify the number of vCPUs. You may change these after provisioning. The capabilities are limited to your customer contract limits. For more information about the contract resource limits in DCD, see Resource Overview.

An SSH key is composed of two files. The first is the private key, which should never be shared. The other is a public key that enables you to access your provisioned Cubes. When you generate the keys, you will use ssh-keygen to store them in a secure location so that you can connect to your instances without encountering the login prompt.
Manually generate SSH keys when working with OpenSSH via the Terminal application by following the steps below.
Enter the following command below into the Terminal window and press ENTER.
The key generation process is initiated by the command above. When you run this command, the ssh-keygen utility prompts you for a location to save the key.

Enter the passphrase that will be used to encrypt the private key file on the disk. You can also press ENTER to accept the default (no passphrase). However, we recommend that you use a passphrase.
Enter your passphrase once more.
After you confirm the passphrase, the public and private keys are generated and saved in the specified location. Thus, the confirmation will look like this:
You can copy the public key to your clipboard by running the following command:
Default keys
Ad-hoc SSH Keys.
Ad-hoc SSH keys, on the other hand, are SSH keys that you only use once and do not intend to save in the SSH Key Manager for future use.
The DCD's SSH Key Manager allows you to save and manage up to 100 public SSH keys for SSH access setup. This saves you from having to copy and paste the public part of an SSH key from an external source multiple times.
Log in to your DCD account after copying the SSH key to the clipboard (Link).
1. Open the SSH Key Manager: Menu > Management > SSH Keys
2. Select the + Add Key in the top left corner.
3. Paste the SSH key from the clipboard into the SSH Key field. If you have saved your SSH Key in a file, you can upload it by selecting the Choose file button in the Select Key file field.
Make sure the SSH keys you enter are valid. The DCD does not validate the syntax or format of the keys.
Optional: Select the Default checkbox to have the SSH key pre-selected when configuring SSH access.
4. Click Save to save the key. The SSH key has now been saved in the SSH Key Manager and is visible in the SSH Key Manager's table of keys.
You can connect to your Cubes instance via OpenSSH. Still, you will need the terminal application, which varies depending on your operating system. For:
Linux: Search Terminal or press CTRL+ALT+T
macOS: Search Terminal
Windows: Search Bash. If you don’t have Bash installed, use PuTTY instead.
The steps below will show you how to connect to your Cubes.
When you log in for the first time, the server isn't recognized on your local machine, so you'll be asked if you're sure you want to keep connecting. You can type yes and then press ENTER.
Authentication is the next step in the connection process. If you've added the SSH keys, you'll be able to connect to the Cubes immediately or after entering your key pair's passphrase.
If you haven't already added SSH keys, you'll be asked for your password:
Nothing is displayed in the terminal when you enter your password, making it easier to paste in the initial password. Pasting into text-based terminals is different from other desktop applications. It is also different from one window manager to another:
For Linux Gnome Terminal, use CTRL+SHIFT+V.
For macOS, use the SHIFT-CMD-V or a middle mouse button.
For Bash on Windows, right-click on the window bar, choose Edit, then Paste. You can also right-click to paste if you enable QuickEdit mode.
Once you’ve entered the password, press ENTER.
Dedicated Core Server configurations are subject to the following limits, according to the CPU type:
AMD CPU: Up to 62 cores and 230 GB RAM
Intel® CPU: Up to 51 Intel® cores and 230 GB RAM
Info: A single Intel® physical core with Hyper-Threading Technology is exposed to the operating system of your Dedicated Core Servers as two distinct “logical cores”, which process separate threads.
Warning: Because the size of the working memory (RAM) cannot be processed during the initial configuration, newly provisioned servers with more than 8 GB of RAM may not start successfully when created from IONOS Windows images.
We recommend initially setting the RAM size to 8 GB; RAM size can then be scaled as needed after the initial provisioning and configuration.
Minimum: 1 GB
Maximum: 4 TB
Minimum: 1 GB
Maximum: 4 TB
Note: You can scale up the HDD and SSD storage volumes as needed.
IONOS data centers are divided into separate areas called Availability Zones.
You can enhance reliability and set up high-availability scenarios by deploying redundant Dedicated Core Servers and storage devices across multiple Availability Zones.
Select the server in the DCD Workspace

Live Vertical Scaling (LVS) technology permits you to scale the number of CPU cores and amount of RAM while the server is running, without having to restart it. Please note that Windows only allows scaling the number of CPU cores, but not the amount of RAM. For scaling to more than eight CPU cores, Windows requires a reboot.
Dedicated Core servers can be restarted at the operating system level (using the reboot command, for instance). You can also use the DCD reset function, which functions similarly to a physical server's reset button.
You should use the DCD to shut down your server completely. Your VM will then be marked as "shut down" in the DCD. Shutting down a VM at the operating system level alone does not deallocate its resources or suspend the billing.
You can delete a Dedicated Core server from the DCD Workspace by right-clicking on it and selecting Delete Server from the list, or by selecting the server and pressing the Del
key on your keyboard.

For IONOS-provided images, you can set the passwords before provisioning.
Newly provisioned servers with more than 8 GB of RAM may not start successfully when created from IONOS Windows images, because the RAM size cannot be processed during the initial configuration.
An error is displayed according to the server version; for example, Windows Server 2012 R2 displays the following message:
"Windows could not finish configuring the system. To attempt to resume configuration, restart the computer."
We recommend initially setting the RAM size to 8 GB, and rescaling it as needed after the initial provisioning and configuration is complete.
The choice of CPU architecture primarily depends on your workload and performance requirements. Intel® processors are oftentimes more powerful than AMD processors. Intel® processors are designed for compute-intensive applications and workloads where the benefits of hyperthreading and multitasking can be fully exploited. Intel® cores cost twice as much as AMD cores. Therefore, it is recommended that you measure and compare the actual performance of both CPU architectures against your workload. You can change the CPU type in the DCD or use the API, and see for yourself whether Intel® processors deliver significant performance gains or more economical AMD cores still meet your requirements.
IONOS is the only cloud computing provider with the unique "Core Technology Choice" feature that can flexibly change the processor architecture per virtual instance.

The device monitors VM/OS crashes. PVPanic is a simulated device, through which a guest panic event is sent to the hypervisor, and a QMP event is generated.
No, the PVPanic device is plug-and-play. However, installing drivers may require a restart.
This is no cause for concern. First of all, you do not need to reboot the VM. However, you will need to reinstall the appropriate drivers (which are provided by IONOS Cloud).
There are no issues found when enabling pvpanic. However, users cannot choose whether or not to enable the device; it is always available for use.
Something else to consider - PVPanic does not offer bidirectional communication between the VM and the hypervisor. Instead, the communication only goes from the VM towards the hypervisor.
There are no special requirements or limitations to any components of a virtualized server. Therefore, PVPanic is completely compatible with AMD and Intel processors.
The PVPanic device is implemented as an ISA device (using IOPORT).
Check the kernel config CONFIG_PVPANIC
parameter.
For example:
m = PVPanic device is available as module y = PVPanic device is native available in the kernel n = PVPanic device is not available
When the device is not available (CONFIG_PVPANIC=n
), use another kernel or image.
For your virtual machines running Microsoft Windows, we provide an ISO image that includes all the relevant drivers for your instance. Just log into DCD, open your chosen virtual data center, add a CD-ROM drive and insert the driver ISO as shown below (this can also be done via CloudAPI).
Note: A reboot is mandatory to add the CD drive.
Once provisioning is complete, you can log into your OS by adding drivers for the unknown device through the Device Manager. Just enter devmgmt.msc
in the Windows search bar, console, or PowerShell to open it.
Since this is a Plug & Play driver, there is no need to reboot the machine.
You can enable IPv6 on Dedicated Core servers and vCPU Servers when you create them or after you create them.
You can set up IPv6 to improve the network connectivity for your virtualized environment. By setting up IPv6 for your Dedicated Core servers and vCPU Servers, you can ensure that they are accessible to IPv6-enabled networks and clients.
Prerequisites: Prior to enabling IPv6, make sure you have the appropriate privileges. New VDC can be created by the contract owners, admins, or users with create VDC privilege. The number of bits in the fixed address is the prefix length. For Data Center IPv6 CIDR, the prefix length is /56.

Steal time in a refers to instances when the hypervisor, responsible for managing VMs and hardware, temporarily reallocates a portion of CPU cycles from dedicated cores to perform essential tasks like storage replication and firewall enforcement. While VMs may perceive this as "stolen processing time," it typically has a low impact on performance, especially with Dedicated Core servers. The IONOS Cloud platform prioritizes efficient resource management to ensure your VMs run smoothly.

IONOS VM Auto Scaling is a cloud computing feature that modifies the number of Virtual Machine (VM) instances in your Virtual Data Center (VDC) automatically based on changes in demand (or the load on your VM).
Note: VM Auto Scaling is currently in the Early Access (EA) phase. We recommend keeping usage and testing to non-production critical applications. For more information, please contact your sales representative or customer support. EA rollout has its limitations. For more information, see limitations.
VM Auto Scaling automatically adds new VM instances when the load increases and reduces the number of instances when the load decreases. This automatic behavior constantly monitors the load and regularly scales the number of VM instances based on the policy threshold. The functionality ensures that the number of replicas in the group remains within the defined limitations.
To configure the feature, create a VM Auto Scaling Group with the following settings:
A group-wide scaling policy based on metrics.
Server replica configuration to automatically add or remove VMs based on demand.
VM Auto Scaling generates or deletes replicas based on the scaling policy, as needed by your application. The metric-based scaling policy tracks the CPU usage or the incoming and outgoing network packets, based on the configuration. When the existing VM instances hit the given threshold, it automatically initiates scaling, either scale in or scale out. Scaling in and scaling out is also called horizontal scaling because it adds additional VMs of the same size but does not increase the size of individual VMs by adding new cores or storage.
Additionally, you can replicate the configuration, such as the CPU architecture, number of cores, network, and group volumes.
VM Auto Scaling interfaces with other IONOS Cloud services, such as the Application Load Balancer (ALB), to maximize resource utilization, improve application scalability, and high-availability of multiple application servers due to server redundancy. You can specify how VM Auto Scaling replicas should be included in the ALB. When enabled, your application automatically scales based on requests from various sources. For example, if you pair VM Auto Scaling with an ALB and your application includes a web service, VM Auto Scaling ensures that your application has enough VM instances to process all requests.
VM Auto Scaling is cost-efficient and improves resource utilization. You pay only for the resources needed to run your application without any additional costs.
You can access and configure VM Auto Scaling via the Data Center Designer (DCD), Cloud API, and the SDK. To start using VM Auto Scaling, see Overview.
Get an overview of VM Auto Scaling.
Get started with VM Auto Scaling via the API.
Get started with VM Auto Scaling via the DCD.
To get answers to the most commonly encountered questions about VM Auto Scaling in DCD, see VM Auto Scaling FAQs.
VM Auto Scaling allows you to automatically scale the number of VM instances horizontally based on the configured policy. This functionality ensures that you have enough VM instances to handle the application loads. It improves efficiency by ensuring that adequate instances are available during peak workloads and saves money by limiting the number of instances available during low workload periods.
This section covers the components of VM Auto Scaling, its features, benefits, and limitations.
The following components are an integral part of VM Auto Scaling:
Auto Scaling group: A collection of VM instances that the VM Auto Scaling manages. VM Auto Scaling automatically adds or removes instances from the group based on the metrics defined for the consumption of resources in the scaling policy.
Scaling policy: Defines how VM Auto Scaling Group scales an instance group based on various parameters such as CPU usage, incoming or outgoing requests, or load balancing utilization. Users can define custom scaling policies and set the desired scaling parameters for the instance group.
VM replica configuration: Defines the properties of the new VM replicas created during the scaling process. The configuration includes the parameters such as CPU type, number of cores, RAM size, network, and volumes.
VM Auto Scaling Manager: Create a VM Auto Scaling Group, define scaling policies, and replicate settings for creating VM instances.
VM Auto Scaling provides the following features:
Automatic Scaling automatically adds or removes VM instances based on the need. It analyzes the resource consumption continuously and scales up the allotted resources when necessary to ensure that the application is always responsive and performing optimally.
Customizable scaling policies allow users to define custom scaling policies based on various parameters, such as CPU usage or network utilization and set the desired scaling parameters for the Auto Scaling group.
Multiple granular scaling policies allow you to specify the number of instance creations when the scaling threshold is reached. Users may choose a policy that best suits their workload requirements.
Integration with other IONOS Cloud services, such as the ALB, enables users to optimize resource utilization and improve application scalability.
VM Auto Scaling provides the following benefits:
Improved resource utilization enables you to allocate resources as needed, thus, improving resource utilization and cost efficiency.
Improved application performance ensures the application is always responsive and performing optimally, thus providing a better user experience.
Improved scalability allows you to scale the application easily and quickly, supporting business growth and increasing revenue.
Reduced operational overhead automates the scaling process, reducing the operational overhead of managing and maintaining VM instances.
This section lists the limitations of VM Auto Scaling:
It is best suited for a gradual increase in demand. The feature uses cooldown timers to scale resources gradually rather than abruptly. As a result, if you anticipate a sudden rise in traffic, we recommend manually adding VMs ahead of time. For example, you could add new VMs before traffic spikes after a TV commercial.
Updating the replica configuration does not affect the existing replicas; however, the changes are only visible when you create new replicas.
To improve the efficiency of the VM Auto Scaling service, we recommend limiting the maximum number of VMs in an Auto Scaling Group to 100 or less. Note that the minimum replica count is one.
Scale in or scale out jobs with a large number of VMs may encounter performance issues. Hence, we recommend limiting the creation or deletion of VMs to at most five, regardless of whether the Amount Type is absolute or percentage.
The capabilities are limited to your customer contract limits. For more information about the contract resource limits in DCD, see .
You can configure VM Auto Scaling via . This feature combines granular configurable options wherein you can create a group and define when the feature must scale in or scale out based on demand. You must also specify the minimum (for scale out) and the maximum (for scale in) number of replicas a group can contain for the replicas to stay within the given threshold.
Configure replicas after configuring thresholds and policies, where you define the settings, network, and storage volumes for the replicas created by the feature. After you define the network, you may add an to the group.

Log in to DCD with your username and password.
Go to Menu > Management > VM Auto Scaling.
Click Servers to view one of these:
click Console to open the remote console to access your VM.
clicking Focus Server opens the VDC and preselects the server automatically.
Configure storage size, networks, and storage volumes for the VM instances. You can also associate an with the group.
Deletion of a VM Auto Scaling Group results in the deletion of all the VMs associated with the respective group.
To delete a group, follow these steps:
Log in to DCD with your username and password.
Go to Menu > Management > VM Auto Scaling.
Click Delete to delete the selected group.
Select the checkbox to confirm deletion.
Enter your Password to proceed with the deletion process.
Select the Skip password verification for the next 60 minutes checkbox if you want to avoid specifiying your password for any operation during the next 60 minutes.
Click OK.
Result: The application deletes the selected VM Auto Scaling Group and the associated VMs, if any.
After successfully configuring your VM Auto Scaling Groups, you can modify scaling thresholds and scaling policies, update replica configuration or associate an ALB via the VM Auto Scaling Manager.
To modify the values, follow these steps:
Log in to DCD with your username and password.
Go to Menu > Management > VM Auto Scaling.
Click on the respective group to modify its values.
You can modify the following:
click Configuration to update the name of the group, modify scaling thresholds and policies.
Note: You cannot modify a DCD after it is associated with the group.
click Replica Configuration to update storage settings, NICs and associated ALBs, or storage volumes.
click Servers to view the servers that are associated with the group.
click Jobs to view the list of tasks.
Click Save to save the changes.
Result: The corresponding VM Auto Scaling Group is successfully modified.
VM Auto Scaling Groups are a collection of virtual servers that automatically scale the number of VM replicas based on the metrics.
Note:
This process is limited to contract owners, administrators, and users with access rights to the data center hosting the VM Auto Scaling Group.
Configuration of a VM Auto Scaling Group triggers the creation of two monitoring alarms for scale in and scale out operations according to the policy settings.
Prerequisites:
When provisioning a VM Auto Scaling Group, ensure that the necessary resources are available and that they are within the configured resource limits of your contract. To check the contract resource limits in DCD, see Resource Overview.
IONOS recommends that you enable CloudInit or use existing images.
Follow these steps to configure a VM Auto Scaling , and define thresholds and scaling policies:
1. Log in to DCD with your username and password.
2. Go to Menu > Management > VM Auto Scaling.
3. Click Create to create a group and define replicas. The Create VM Auto Scaling Group window displays the Configuration and the Replica Configuration tabs.
4. Define the following in the Configuration tab:
5. Configure replicas. For more information, see Configure replicas.
Important: The application applies a default replica setup if you do not configure replicas. Hence, we recommend that you configure replicas before you click Create. It is also mandatory, as the ALB uses the IP addresses of the NICs linked to the VM instances. Provisioning the replica defaults does not configure a network, thus, the associated ALB is left without NICs or IP addresses.
6. Click Create to save the configuration.
Result: Your VM Auto Scaling Group is successfully configured. You can now manage it via the VM Auto Scaling Manager.
You can specify a name for your VM Auto Scaling Group and the minimum number and the maximum number of VM instances it can contain during scaling. The minimum number ensures that you never run out of VM instances and the group always has at least one VM instance. The feature cannot provide more than the maximum number of VM instances during a scale out operation.
To create a VM Auto Scaling Group, go to the Configuration tab in the Create VM Auto Scaling Group window and specify the following:
Name: Enter a name for the VM Auto Scaling Group.
Data Center: Select a data center from the drop-down list. You can either select an existing Virtual Data Center (VDC) or create a new one if required. The application lists all the VDCs in your DCD. The group is valid only within the selected VDC to which it belongs.
Minimum Count: Enter the minimum number of VMs the group must scale to. The minimum replica count is one. VM Auto Scaling uses this as a reference value to stop deleting VM instances for a group. This is necessary to ensure that scaling does not reduce the VM instances beyond the specified count.
Maximum Count: Enter the maximum number of VMs the group must scale to. VM Auto Scaling uses this as a reference value to stop adding new VM instances for a group. This is necessary to ensure that scaling does not increase beyond the specified count. To improve the efficiency of the VM Auto Scaling service, we recommend limiting the maximum number of VMs in an Auto Scaling Group to 100 or less.
A Policy defines the rules to trigger VM Auto Scaling to analyze the resource utilization rate at regular intervals. You can only define one metric policy per group that triggers the scaling process.
To define policies, go to the Configuration tab in the Create VM Auto Scaling Group window and specify the following:
Metric: Select a metric from the drop-down list whose performance must be monitored. The pre-defined values are based on the CPU utilization average or network bytes for incoming and outgoing bytes or packets.
Scale In Threshold: Enter a value to specify when VM Auto Scaling must trigger the scale in operation. The value specified here indicates the percentage of the CPU utilization rate or the network packets or network bytes, based on which the scale in action is triggered for the metric. For example, if you specify the CPU utilization rate as 30, VM Auto Scaling automatically begins scaling inwards and deletes the additional VM instances when the CPU utilization rate is 30%.
Scale Out Threshold: Enter a value to specify when VM Auto Scaling must trigger the scale out operation. The value specified here indicates the percentage of the CPU utilization rate or the network packets or bytes based on which the scale-out action is triggered for the metric. For example, if you specify the value as 70, the application automatically begins scaling outwards and adds additional VM instances when the CPU utilization rate reaches 70%.
Note: Ensure that the Scale In Threshold and the Scale Out Threshold field values differ by 40%. For example, if you set the Scale In Threshold to 15%, Scale Out Threshold cannot contain a value lesser than 55%.
Range: Enter a time range in hours, minutes, or seconds. Example: 1h, 3m, 120s. It is the period during which VM Auto Scaling measures the percentage of chosen metric utilization at regular intervals and automatically scales in or scales out based on the demand. If specifying in seconds, ensure that the value is not less than 120 seconds.
Unit: Select a unit from the drop-down list. You can specify whether the scaling process should be initiated every hour, minute, or second for other predefined metrics. This is automatically set to Total for an instance CPU utilization average metric.
Scale in defines the action triggered during a scale in operation. Based on the values defined, the feature automatically deletes the specified number of VM instances after the cooldown period.
To define scale in policies, go to the Configuration tab in the Create VM Auto Scaling Group window and specify the following:
Amount Type: Select a value from the drop-down list to define the number of replicas that must be deleted. You can choose either Percentage or Absolute.
Amount: Enter the number of VM instances to be deleted during a scale in operation. The minimum value is one. Scale in jobs with a large number of VMs may encounter performance issues. Hence, we recommend limiting the deletion of VMs to at most five, regardless of whether the Amount Type is absolute or percentage.
Cooldown Period: Enter the cooldown period to indicate the interval between each auto scaling action in the group. The cooldown period can be measured in minutes, seconds, or hours. For example, when the value is set to 5m, the scale in action is activated every 5 minutes. VM Auto Scaling automatically deletes the given number of VM instances when the resource consumption is lower.
Note:
Only one scaling action remains in progress for a VM Auto Scaling Group. The metric is reevaluated after the current scaling action completes.
The minimum value is two minutes, and the maximum value is 24 hours.
If specifying in seconds, ensure the minimum value is not less than 120 seconds.
The application considers the default value of five when a period is not specified.
Termination Policy: Select a value from the drop-down list to choose whether the oldest or the most recent replica must be deleted first. Choosing the Oldest replica first delegates the scaling process to delete the oldest replicas. Otherwise, choose the Youngest replica first to begin scaling by deleting the most recent replica.
Delete attached volumes: Select a value from the drop-down list to indicate if the attached volumes must be deleted. Choose Don’t delete to retain the attached volumes; otherwise, choose Delete.
Scale out defines the action triggered during a scale out operation. The feature automatically adds the specified number of VM instances after the cooldown period based on the demand.
To define scaling out policies, go to the Configuration tab in the Create VM Auto Scaling Group window and specify the following:
Amount Type: Select a value from the drop-down list to define the number of replicas added when the metric utilization exceeds the specified amount. You can choose either Percentage or Absolute.
Amount: Enter a number to indicate the number of VM instances that must be added. The minimum value is one. Scale out jobs with a large number of VMs may encounter performance issues. Hence, we recommend limiting the addition of VMs to at most five, regardless of whether the Amount Type is absolute or percentage.
Cooldown Period: Enter the cooldown period to indicate the interval between each auto scaling process in the group. The cooldown period can be measured in minutes, seconds, or hours. For example, when the value is set to 5m, the scale out process is activated every 5 minutes. VM Auto Scaling automatically adds the given number of VM instances when the resource consumption is higher. The notes mentioned in scale in policies are also applicable to scale out policies.
Managed Kubernetes provides a platform to automate the deployment, scaling, and management of containerized applications. With IONOS Cloud Managed Kubernetes, you can quickly set up Kubernetes clusters and manage Node Pools.
It offers a wide range of features for containerized applications without having to handle the underlying infrastructure details. It is a convenient solution for users who want to leverage the power of Kubernetes without dealing with the operational challenges of managing the cluster themselves.
In the Replica Configuration tab, you can configure the size, networks, and storage volumes for the VM instances that VM Auto Scaling creates. You may also use the CloudInit mechanism to configure VM instances.
You can configure the following on the Replica Configuration tab:
Note:
During the EA phase, it is possible to delete replicas manually. Manual deletion of replicas does not remove the IP address of the replica from the Targets list (Management > Target Groups > select a Target Group and click Targets); ensure that you remove them manually from the Targets list before you delete the associated replica.
To configure VM replica settings, follow these steps:
Go to the Replica Configuration tab in the Create VM Auto Scaling Group window and configure the Settings, Network, and Volumes tabs.
Click Clone Settings and Volumes from the drop-down list to clone the CPU Architecture, Cores, and RAM automatically from your VMs in the VDC. You can also use the slider to configure them manually.
Name: Enter a name for the NIC.
DHCP: Select the checkbox to provision IP addresses for your VM instances.
LAN: Enter the LAN ID to be used for accessing the VM instances on the network.
Firewall active: Select the checkbox to activate the firewall. By default, an active firewall without defined rules blocks all incoming network traffic except for the rules that explicitly allow specific protocols, IP addresses, and ports.
Firewall Type: Select Ingress, Egress, or Bidirectional to choose firewall rules for the type of queries that will be allowed on the NIC. By default, Ingress is used if you do not specify a value.
Firewall Rules: Click Manage Rules to allow managing requests from external networks. When configured, all firewall rules defined for the specified NIC are listed.
Flow Logs: Select a flow log from the drop-down list to log all network packets. The list of all flow logs for the specified NIC is displayed. You can instantly create a new flow log, if necessary.
Note: During the EA phase, Flow Logs are not supported. If you apply a configuration, the creation of VM Auto Scaling Groups will fail.
VM Auto Scaling creates VM instances based on the specified storage volumes during scaling.
Name: Enter a name for the storage volume.
Boot device: Select a value from the drop-down list to use the corresponding volume as a boot volume. You can select one of these values:
Choose Auto to allow VDC to delegate the provisioning engine to select the boot volume automatically.
Choose Primary to set the configured volume as a boot volume.
Choose None if you do not want to configure a boot volume.
Note: You can either set one volume to Primary or set all volumes to Auto.
Bus: Select a driver from the drop-down list. The predefined values are VIRTIO and IDE.
Storage Type: Select either HDD, SSD Premium or SSD Standard from the drop-down list to configure the type of storage. IONOS provides three different types of disks and you can choose to attach either of these to the VM Auto Scaling Group.
Size in GB: Specify the size of the selected storage type.
Image: Select either an Image or an Image Alias from the drop-down list to associate it with a VM Auto Scaling Group. A Password is mandatory to configure either of these. You can also associate the following with the storage volume:
SSH keys: Select the checkbox to use the SSH keys to validate the request and create an encrypted connection for communication.
Cloud-Init User Data: Click No configuration to specify the user data (Cloud-Init) for this replica volume.
Backup Unit: Select a backup unit from the drop-down list, if already configured. Otherwise, you can create one instantly. Backups of VM instances are stored in the associated backup unit regularly.
Important: The VM Auto Scaling feature creates replicas based on the configuration. Changes to the existing configuration will only apply to new replicas but not the instances that are already running. Hence, we recommend that you configure Settings, Network, and Volumes before clicking Create to avoid any discrepancies later.
Click Create to configure your VM Auto Scaling Group.
Result: Your VM Auto Scaling Group is successfully configured and can be managed via the VM Auto Scaling Manager.
When you associate an ALB with a replica configuration, the ALB can use all of the VM replicas created by the VM Auto Scaling feature, which means your application can scale and receive requests from different queries based on the configured ALB.
To associate an ALB with a replica configuration, go to the Replica Configuration tab in the Create VM Auto Scaling Group window and specify the following:
Target Group: Select a value from the drop-down list. You can also click Create new Target Group from the drop-down list to instantly create a new target group. When you specify a target group, the scaling process associates replicas with the target groups. The ALB checks these target groups to verify the available IP addresses to process requests.
Note: You cannot delete a target group if it is associated with the replica of the VM AutoScaling group and in use. We recommend deleting the AutoScaling group first before deleting the target group.
Port: Select a value from the drop-down list to decide the port on which the queries must be redirected. It is recommended to set the port to TCP port 80. This port is used by the ALB to distribute traffic to individual replicas.
Weight: The traffic is distributed proportionally to the target weight, which is the ratio of the total weight of all targets. A target with a higher weight receives a larger share of traffic. The valid range is from 1 to 256. We recommend using values in the middle range to leave room for later adjustments.

In IONOS Managed Kubernetes, a Private Node Pool is a dedicated set of nodes within a Kubernetes cluster that is isolated for the exclusive use of a specific user, application, or organization. Private node pools of a cluster are deployed in a private network behind a NAT Gateway to enable connectivity from the nodes to the public internet but not vice-versa.
You can create Kubernetes clusters for Private Node Pools using the Configuration Management Tools or directly using the IONOS Cloud API. By using IONOS Kubernetes clusters for Private Node Pools, you can ensure the network traffic between your nodes and Kubernetes service stays on your private network only.
The key features related to Private Node Pools include:
Customized Configurations: The ability to customize networking configurations and define subnets provides flexibility to align the infrastructure with user-specific requirements.
Isolation of Resources: Private Node Pools provide isolation of resources that improves the performance and reduces the risk of interference from external entities. The isolation of resources within a dedicated, private network environment.
Security: The additional layer of security added by Private Node Pools ensures that nodes are only accessible within a private network. This helps in protecting sensitive data and applications from external threats.
Scalability: The Private Node Pools are designed to be flexible and scalable based on your needs. This ensures that the resources are utilized efficiently, and you can adapt to varying levels of demand.
VM Auto Scaling is a managed service designed to launch or terminate VM instances horizontally to ensure you have the appropriate number of instances available to handle the load on your application.
You can optimize cost by reducing the number of VMs needed to run in parallel while ensuring your setup does not run into resource limitations.
One of your scaling policies was met. For example, when CPU utilization exceeds the defined threshold, you may check the Auto Scaling logs to see why a scaling action was triggered.
It is a defined group of VMs created from the same image template by the VM Auto Scaling feature.
When you delete the VM instances, all the underlying VMs will be deleted.
The Jobs tab contains information about the scaling operations that the feature initiates. You can view a list of actions triggered by the feature, its status, and when the process started.
If not explicitly configured differently, VM Auto Scaling deletes the oldest VM in your Auto Scaling group first when a scale in action is triggered. Thus changes will be propagated naturally through your group of VMs.
When your VM Auto Scaling Group qualifies for a scale in action according to the metrics you set, the oldest running VM in your group will be stopped. You repeat this process until all VMs are updated.
Currently, VM Auto Scaling only supports horizontal scaling. This means that the feature creates more VMs to support your workload based on the replica configuration of the appropriate group.
Note: The VM Auto Scaling feature does not handle VMs that are not part of a VM Auto Scaling Group. You will need to manually update them.
Although the feature now allows horizontal scaling, you can manually modify the replica configuration of a group. For example, you can increase the resources associated with your VMs, such as CPU cores or the size of the RAM. This notion is identical to vertical scaling (scaling up). After you save the configuration, the replicas created as part of the subsequent scale-out process contain the updated configuration. As mentioned earlier, for this change to propagate to all your VMs, the scaling in policy must be explicitly configured to delete the oldest replicas.
You can choose if the volumes must be retained when a VM is scaled in. Remember that choosing to retain the volumes during scale in process accumulates data over time.
You can combine VM Auto Scaling with an ALB to spread the load evenly across your VMs. You may also use CloudInit to configure your VMs during bootup based on the workload.
A Cross Connect is a feasible alternative to connect replicas on two different subnets. Hence, groups with replicas connected to these subnets will be connected via Cross Connect. Moreover, ensure that you make the necessary configurations as you would for VMs to communicate with one another. The approach is similar to physically connecting two subnets using a network cable.
Yes, the replicas (or VM instances) created as part of the scaling process function in the same way as the IONOS Cloud VMs configured in the VDC. For example, you can configure it with an ALB, Network Load Balancer, NAT Gateway, Managed Kubernetes clusters, and MongoDB clusters.
Managed Kubernetes facilitates the fully automated setup of Kubernetes clusters. Using Managed Kubernetes, several clusters can be quickly and easily deployed. For example, you can use it on the go to set up staging environments and then delete them if required. Managed Kubernetes simplifies and supports the automation of Continuous Integration and Continuous Delivery/Continuous Deployment (CI/CD) pipelines that help in testing and deployment.
IONOS Managed Kubernetes offers the following:
Automatic updates and security fixes.
Version and upgrade provisioning.
Highly available and geo-redundant control plane.
Full cluster administrator level access to Kubernetes API.
Both Public and Private Node Pools support the same Kubernetes versions.
Note:
You can explore the available releases for Kubernetes. For more information, see Release History.
You can visit the changelog to explore the information related to your Kubernetes version. For more information, see Changelog.
The architecture of Managed Kubernetes includes the following main components that collectively provide a streamlined and efficient environment for deploying, managing, and scaling containerized applications.
Control Plane: The control plane runs several key components, including the API server, scheduler, and controller manager. It is responsible for managing the cluster and its components, coordinates the scheduling and deployment of applications, monitors the health of the cluster, and enforces desired state management.
Cluster: A cluster is a group of computing resources that are connected and managed as a single entity. It is the foundation of the Kubernetes platform and provides the environment for deploying, running, and managing containerized applications. Clusters can span multiple node pools that may be provisioned in different virtual data centers and across locations. For example, you can create a cluster consisting of multiple node pools where each pool is in a different location and achieve geo-redundancy. Each cluster consists of a control plane and a set of worker nodes.
Node: A single (physical or virtual) machine in a cluster is part of the larger Kubernetes ecosystem. Each node is responsible for running containers, which are the encapsulated application units in Kubernetes. These nodes work together to manage and run containerized applications.
Node Pool: A node pool is a group of nodes within a cluster with the same configuration. Nodes are the compute resources where applications run. All Kubernetes worker nodes are organized in node pools. All nodes within a node pool are identical in setup. The nodes of a pool are provisioned into virtual data centers at a location of your choice, and you can freely specify the properties of all the nodes at once before creation.
kubectl
: The command-line tool for interacting with Kubernetes clusters that serves as a powerful and versatile interface for managing and deploying applications on Kubernetes. With kubectl
, you can perform various operations such as creating, updating, and deleting resources in a Kubernetes cluster.
Kubeconfig
: The kubeconfig
file is a configuration file used by the Kubernetes command-line tool (kubectl
) to authenticate and access a Kubernetes cluster. It contains information about the cluster, user credentials, and other settings.
etcd: etcd is a distributed key-value store that is used as the primary data store for Kubernetes. It is responsible for storing the configuration data that represents the state of the cluster. This includes information about nodes in the cluster, configurations, and the current status of various resources.
The illustration shows the key components of the Managed Kubernetes.
Kubernetes is organized in clusters and node pools. The node pools are created in the context of a cluster. The servers belonging to the node pool are provisioned into the Virtual Data Center (VDC). All servers within a node pool are identical in their configuration.
Nodes, also known as worker nodes, are the servers in your data center that are managed by Kubernetes and constitute your node pools. All Resources managed by Kubernetes in your data centers will be displayed by the DCD as read-only.
You can see, inspect, and position the managed resources as per your requirements. However, the specifications of the resources are locked for manual interactions to avoid undesirable results. To modify the managed resources, use the Kubernetes Manager. You can manage the following resource types based on your deployed pods and configurations:
Servers
The Inspector for Managed Resources allows easy navigation between the data centers, clusters, and node pools in the Kubernetes Manager. Here, you can:
Switch to the Kubernetes Manager and show the respective node pool.
Download the kubeconfig
to access the cluster.
List all nodes in the data center belonging to the same node pool.
All operations related to the infrastructure of clusters can be performed using the Kubernetes Manager, including cluster and node creation and scaling of node pools. The status of a cluster is indicated by different statuses.

Some applications require a Kubernetes service of type LoadBalancer
, which preserves the source IP address of incoming packets. Example: Ingress controllers. You can manually integrate a Network Load Balancer (NLB) by exposing and attaching a public IP address to a viable Kubernetes node. This node serves as a load balancer using kube-proxy.
Note:
This works fine with services that use externalTrafficPolicy: Cluster
, but in this case, the client's source IP address is lost.
The public IP address that is used as the Load Balancer IP address also needs to be bound to those nodes on which the ingress controller is running.
To preserve the client source IP address, Kubernetes services with externalTrafficPolicy: Local
need to be used. This configuration ensures that packets reaching a node are only forwarded to Pods that run on the same node, preserving the client source IP address. Therefore, the load balancer IP address of the service needs to be attached to the same node running the ingress controller pod.
This can be achieved with different strategies. One approach is to use a DaemonSet to ensure that a pod is running on each node. However, this approach is feasible only in some cases, and if a cluster has a lot of nodes, then using DaemonSet could lead to a waste of resources.
For an efficient setup, you can schedule Pods to be run only on nodes of a specific node pool using nodeSelector. The node pool needs to have labels that can be used in the node selector. To ensure that the service's load balancer IP is also attached to one of these nodes, annotate the service with cloud.ionos.com/node-selector: key=value
, where the key and value are the labels of the node pool.
The following example shows how to install the ingress-nginx helm chart as a DaemonSet with node selector and to configure the controller service with the required annotation.
Create a node pool with a label nodepool=ingress
:
Create a values.yaml
file for later use in the helm command with the following content:
Install ingress-nginx via helm using the following command:
It is desirable to extend CoreDNS with additional configuration to make changes that survive control plane maintenance. It is possible to create a ConfigMap in the kube-system
namespace. The ConfigMap must be named coredns-additional-conf
and contain a data entry with the key extra.conf
. The value of the entry must be a string containing the additional configuration.
The following example shows how to add a custom DNS entry for example.abc

The release schedule outlines the timeline for Kubernetes versions, updates, availability, and the deployment of new features within the Managed Kubernetes environment. It also provides an estimated release and End of Life (EOL) schedule.
The Managed Kubernetes release schedule provides the following information:
Kubernetes Version: This refers to a specific release of the Kubernetes, which includes updates, enhancements, and bug fixes.
Kubernetes Release Date: The date when a specific version of the Kubernetes software is released, making it available for users to download and deploy.
Availability Date: This is an estimate of the version release of the new feature that becomes accessible or ready for use.
Kubernetes End of Life (EOL): The date when a specific version or release of Kubernetes reaches the end of its official support and maintenance period, after which it no longer receives updates, security patches, or bug fixes from the Kubernetes community or its maintainers. These versions may still be available in the Managed Kubernetes product but will soon be removed from the available versions.
End of Life (EOL): The point in time when the Managed Kubernetes product reaches the end of its official support period, after which it will no longer receive updates, patches, or technical assistance.
The horizontal scaling of ingress network traffic over multiple Kubernetes nodes involves adjusting the number of running instances of your application to handle varying levels of load. This helps preserve the original client IP address forwarded by the Kubernetes ingress controller in the X-Forwarded-For HTTP header.
The following example contains a complete configuration file, including parameters and values to customize the installation:
The illustration shows the high-level architecture built using IONOS Managed Kubernetes.
The current implementation of the service of type LoadBalancer does not deploy a true load balancer in front of the Kubernetes cluster. Instead, it allocates a static IP address and assigns it to one of the Kubernetes nodes as an additional IP address. This node is, therefore, acting as an ingress node and takes over the role of a load balancer. If the pod of the service is not running on the ingress node, kube-proxy will NAT the traffic to the correct node.
Problem: The NAT operation will replace the original client IP address with an internal node IP address.
Any individual Kubernetes node provides a throughput of up to 2 Gbit/s on the public interface. Scaling beyond that can be achieved by scaling the number of nodes horizontally. Additionally, the service LB IP address must also be distributed horizontally across those nodes. This type of architecture relies on Domain Name System (DNS) load balancing, as all LB IP addresses are added to the DNS record. During name resolution, the client will decide which IP address to connect to.
When using an ingress controller inside a Kubernetes cluster, web services will usually not be exposed as type LoadBalancer, but as type NodePort instead. The ingress controller is the component that will accept client traffic and distribute it inside the cluster. Therefore, usually only the ingress controller service is exposed as type LoadBalancer.
To scale traffic across multiple nodes, multiple LB IP addresses are required, which are then distributed across the available ingress nodes. This can be achieved by creating as many (dummy) services as nodes and IP addresses are required. It is best practice to reserve these IP addresses outside of Kubernetes in the IP Manager so that they are not unassigned when the service is deleted.
Let’s assume that our web service demands a throughput of close to 5 Gbit/s. Distributing this across 2 Gbit/s interfaces would require 3 nodes. Each of these nodes requires its own LB IP address, so in addition to the ingress controller service, one needs to deploy 2 additional (dummy) services.
To spread each IP address to a dedicated node, use a node label to assign the LB IP address to: node-role.kubernetes.io/ingress=<service_name>
Note: You can always set labels and annotations via the DCD, API, Terraform, or other DevOps tools.
To pin a LB IP address to a dedicated node, follow these steps:
Reserve an IP address in the IP Manager.
Create a node pool of only one node.
Apply the following label to the node:
node-role.kubernetes.io/ingress=<service_name>
Add the following node selector annotation to the service:
annotations.cloud.ionos.com/node-selector: node-role.kubernetes.io/ingress=<service_name>
In the case of our example, reserve 3 IP addresses in the IP Manager. Add these 3 IP addresses to the DNS A-record of your fully qualified domain name. Then, create 3 node pools, each containing only one node, and apply a different ingress node-role label to each node pool. We will call these 3 nodes as ingress nodes.
The first service will be the ingress NGINX controller service. Add the above-mentioned service annotation to it:
controller.service.annotations.cloud.ionos.com/node-selector: node-role.kubernetes.io/ingress=<service_name>
Also, add the static IP address (provided by the IP Manager) to the configuration:
controller.service.loadBalancerIP: <LB_IP_address>
Similarly, 2 additional (dummy) services of type LoadBalancer must be added to spread traffic across 3 nodes. These 2 services must point to the same ingress-nginx deployment, therefore the same ports and selectors of the standard ingress-nginx service are used.
Note:
Make sure to add your specific LB IP address to the manifest.
Notice the service is using the service specific node selector label as annotation.
This spreads 3 IP addresses across 3 different nodes.
To avoid packets being forwarded using Network Address Translation (NAT) to different nodes (thereby lowering performance and losing the original client IP address), each node containing the LB IP address must also run an ingress controller pod. (This could be implemented by using a daemonSet, but this would waste resources on nodes that are not actually acting as ingress nodes.) First of all, as many replicas of the ingress controller as ingress nodes must be created (in our case 3): controller.replicaCount: 3
Then, the Pods must be deployed only on those ingress nodes. This is accomplished by using another node label. For example, node-role.kubernetes.io/ingress-node=nginx
. The name and value can be set to any desired string. All 3 nodes must have the same label associated. The ingress controller must now be configured to use this nodeSelector:
controller.nodeSelector.node-role.kubernetes.io/ingress-node: nginx
This limits the nodes on which the Ingress Controller Pods are placed.
For the Ingress Controller Pods to spread across all nodes equally (one pod on each node), a pod antiAffinity must be configured:
To force Kubernetes to forward traffic only to Pods running on the local node, the externalTrafficPolicy needs to be set to local. This will also guarantee the preservation of the original client IP address. This needs to be configured for the Ingress-NGINX service (controller.service.externalTrafficPolicy: Local) and for the 2 dummy services (see full-service example above).
The actual helm command via which the Ingress-NGINX Controller is deployed is as follows:
helm install ingress-nginx ingress-nginx --repo https://kubernetes.github.io/ingress-nginx --namespace ingress-nginx --create-namespace -f values.yaml
To verify the setup, ensure that:
DNS load balancing works correctly.
Fully Qualified Domain Name (FQDN) DNS lookup yields three IP addresses.
The Whoami web application can be deployed using the following manifests:
Note: Ensure that both Whoami Pods are running, the service is created, and the Ingress returns an external IP address and a hostname.
A curl with the below-mentioned flags to the hostname will show which Load Balancer IP address is used. You need to use the same curl command multiple times to verify connection to all 3 LB IP addresses is possible.
The response from the whoami application will also return the client IP address in the X-Forwarded-For HTTP header. Verify that it is your local public IP address.
The will be installed via using a separate configuration file.
You can optimize the compute resources, such as CPU and RAM, along with storage volumes in Kubernetes through strategic usage of zones.To enhance the performance of your Kubernetes environment, consider implementing a strategic approach for resource allocation. You can intelligently distribute workloads across different zones to improve performance and enhance fault tolerance and resilience.
Define a storage class named ionos-enterprise-ssd-zone-1
, which specifies the provisioning of SSD-type storage with ext4
file system format, located in availability zone ZONE_2
. Configure the volumeBindingMode
and allowVolumeExpansion
fields.
Note: Supported values for fstype
are ext2
, ext3
or ext4
.
This implementation provides a robust and reliable Kubernetes infrastructure for your applications.
You can use the Load Balancer to provide a stable and reliable IP address for your Kubernetes cluster. It will expose your application, such as Nginx deployment, to the internet. This IP address should remain stable as long as the service exists.
Define type
as LoadBalancer
to create a service of type Load Balancer. When this service is created, most cloud providers will automatically provision a Load Balancer with a stable external IP address. Configure the ports
that the service will listen on and forward the traffic to. Define the selector
field to set the Pods to which the traffic will be forwarded.
Note:
Ensure that your Cloud provider supports the automatic creation of external Load Balancers for Kubernetes services.
You need at least two remaining free CRIPs for regular maintenance.
You need to replace the Nginx
related labels and selectors with those relevant to your application.

All Managed Kubernetes resources, such as clusters and node pools, are subject to an automated weekly maintenance process. All changes to a cluster or node pools that may cause service interruption, such as upgrades, are executed during maintenance. During the maintenance window, you may encounter uncontrolled disconnections and an inability to connect to the cluster.
The upgrade process during maintenance respects the selected Kubernetes version of the cluster. The upgrade process does not upgrade to another Kubernetes major, minor, or patch version unless the current cluster or node pool version reaches its end of life. In such instances, the cluster or node pool will be updated to the next minor version that is active.
The maintenance window consists of two parts. The first part specifies the day of the week, while the second part specifies the expected time. The following example shows a maintenance window configuration:
For more information, see Create a Cluster.
During cluster maintenance, control plane components are upgraded to the newest version available.
During the maintenance of a particular node pool, all nodes of this pool will be replaced by new nodes. Nodes are replaced one after the other, starting with the oldest node. During the node replacement, first, a new node is created and added to the cluster. Then, the old node is drained and removed from the cluster. Node pool upgrade considers the four-hour maintenance window. The upgrade process will be continued in the next node pool maintenance if it fails to upgrade all nodes of the node pool within the four-hour maintenance window.
The maintenance process first tries to drain a node gracefully, considering the given PDBs for one hour. If this fails, the node is drained, ignoring pod disruption budgets.
Prerequisite: You need administrative privileges to create and assign user privileges by using the Cloud API.
To set user privileges using the Cloud API for creating clusters, follow these steps:
Authenticate to the Cloud API using your API credentials.
Create a user using the POST /cloudapi/v6/um/users
endpoint.
Set the following required parameters for the user: user's name
, email address
, and password
.
Create a group using the POST /cloudapi/v6/um/groups
endpoint.
Set createK8sCluster privilege to true
.
Assign the user to the created group using POST /cloudapi/v6/um/groups/{groupId}/users
endpoint and provide the user ID in the header.
Result: The Create Kubernetes Clusters privilege is granted to the user.
All Kubernetes API instructions can be found in the main Cloud API specification file.
To access the Kubernetes API, which the cluster provides, you can download the kubeconfig
file and use it with tools such as kubectl
.
GET
https://api.ionos.com/cloudapi/v6/k8s/{k8sClusterId}/kubeconfig
Retrieve a configuration file for the specified Kubernetes cluster, in YAML or JSON format as defined in the Accept header; the default Accept header is application/yaml.
You can add user groups and assign permissions for Public and Private Node Pools with the Kubernetes Manager in DCD.
In the clusters for Public Node Pools, nodes only have external IP addresses, which means that the nodes and pods are exposed to the internet.
To set up the security settings, follow these steps:
In the DCD, go to Menu > Containers > Managed Kubernetes.
In Kubernetes Manager, select a cluster.
Go to the Security tab and click Visible to Groups.
To enable access, select the Edit or Share checkbox for a group.
Note: To disable access, select the group for which you want to disable access. Clear either the Edit or Share checkboxes. You can also directly click Remove Group.
Result: The cluster for Public Node Pools now has the newly assigned permissions.
In the clusters for Private Node Pools, nodes only have internal IP addresses, which means that the nodes and pods are isolated from the internet. Internal IP addresses for nodes come from the primary IP address range of the subnet you choose for the cluster.
To set up the security settings, follow these steps:
In the DCD, go to Menu > Containers > Managed Kubernetes.
In Kubernetes Manager, select a cluster.
Go to the Security tab and click Visible to Groups.
To enable access, select the Edit or Share checkbox for a group.
Note: To disable access, select the group you want to disable the access for. Clear either the Edit or Share checkboxes. You can also directly click Remove Group.
Result: The cluster for Private Node Pools now has the newly assigned permissions.
A node pool upgrade generally happens automatically during weekly maintenance. You can also trigger it manually. For example, when upgrading to a higher version of Kubernetes. In any case, the node pool upgrade will result in rebuilding all nodes belonging to the node pool.
During the upgrade, an old node in a node pool is replaced by a new node. This may be necessary for several reasons:
Software updates: Since the nodes are considered immutable, IONOS Cloud does not install software updates on the running nodes but replaces them with new ones.
Configuration changes: Some configuration changes require replacing all included nodes.
Considerations: Multiple node pools of the same cluster can be upgraded at the same time. A node pool upgrade locks the affected node pool, and you cannot make any changes until the upgrade is complete. During a node pool upgrade, all of its nodes are replaced one by one, starting with the oldest one. Depending on the number of nodes and your workload, the upgrade can take several hours.
If the upgrade is initiated as a part of weekly maintenance, some nodes may not be replaced to avoid exceeding the maintenance window.
Make sure that you have not exceeded your contract quota for servers; otherwise, you will not be able to provision a new node to replace an existing one.
The rebuilding process consists of the following steps:
Provision a new node to replace the old one and wait for it to register in the control plane.
Exclude the old nodes from scheduling to avoid deploying additional pods to it.
Drain all existing workload from the old node.
At first, the IONOS Cloud tries to drain the node gracefully.
If the process takes more than 1 hour, all remaining pods are deleted.
Delete the old node from the node pool.
You need to consider the following node drain updates and their impact on the maintenance procedure:
Under the current platform setup, a node drain considers PDBs. If a concrete eviction of a pod violates an existing PDB, the drain would fail. If the drain of a node fails, the attempt to delete this node will also fail.
The problems with unprepared workloads or misconfigured PDBs can lead to failing drains, node deletions, and resulting failure in node pool maintenance. To prevent this issue, the node drain will split into two stages. In the first stage, the system will continue to try to gracefully evict the pods from the node. If this fails, the second stage will forcefully drain the node by deleting all remaining pods. This deletion will bypass checking PDBs. This prevents nodes from failing during the drain.
As a result of the two-stage procedure, the process will stop failing due to unprepared workloads or misconfigured PDBs. However, this change may cause interruptions to workloads that are not prepared for maintenance. During maintenance, nodes are replaced one by one. For each node in a node pool, a new node is created. After that, the old node is drained and then deleted.
At times, a pod is not able to return to its READY state after being evicted from a node during maintenance. In such cases, a PDB was in place for a pod's workload. This leads to failed maintenance, and the rest of the workload is left untouched. With the force drain behavior, the maintenance process will proceed, and all parts of the workload will be evicted and potentially end up in a non-READY state. This might lead to an interruption of the workload. To prevent this, make sure that your workload pods are prepared for eviction at any time.
Following are a few limitations that you can encounter while using both Public and Private Node Pools:
The maximum number of pods supported per node is 110. It is a Kubernetes default value.
The recommended maximum number of nodes per node pool is 20.
The maximum number of nodes in a node pool is 100.
A total of 500 node pools per cluster is supported.
The recommended maximum number of node pools per cluster are 50.
The maximum number of supported nodes per cluster is 5000.
Following are a few limitations that you can encounter while using Private Node Pools:
Kubernetes services of type LoadBalancer are currently not supported.
The static node Internet Protocol (IP) addresses are not supported.
Managed Kubernetes facilitates the fully automated setup of Kubernetes clusters. Managed Kubernetes also simplifies and carefully supports the automation of Continuous Integration and Continuous Delivery/Continuous Deployment (CI/CD) pipelines for testing and deployment.
IONOS Managed Kubernetes solution offers automatic updates, security fixes, versioning, upgrade provisioning, high availability, geo-redundant control plane, and full cluster administrator level access to Kubernetes API.
Everything related to Managed Kubernetes can be controlled in the DCD via the dedicated Kubernetes Manager. The Manager provides a complete overview of your provisioned Kubernetes clusters and node pools, including their statuses. The Manager allows you to create and manage clusters, create and manage node pools, and download the kubeconfig
file.
The control plane manages the worker nodes and the pods in the cluster. In production environments, the control plane usually runs across multiple computers. A cluster usually runs multiple nodes, providing fault tolerance and high availability.
Managed Kubernetes supports regional control planes that provide a distributed and highly-available management infrastructure within a chosen region. It also offers a hidden control plane for both Public and Private Node Pools. Control plane components like kube-apiserver
, kube-scheduler
, and kube-controller-manager
are not visible to the users and cannot be modified directly.
The kube-apiserver can only be interacted with by using its REST API.
Managed Kubernetes does not currently offer an option to choose a different CNI plugin, nor does it support customers that do so on their own.
CNI affects the whole cluster network, so if changes are made to Calico or a different plugin is installed, it can cause cluster-wide issues and failed resources.
Mount options in the PersistentVolume
specification can also be set using the StorageClass.
This may be desired when a dynamically provisioned volume is left over or if an external volume should be exposed to Kubernetes workload.
Warning: Do not import your Managed Kubernetes node's root volumes. They are fully managed outside the Kubernetes cluster, and importing them will cause conflicts that may lead to service disruptions and data loss.
Dynamically provisioned PVs are created by the CSI driver, which populates the resource ownership annotations and information gathered from the IONOS Cloud API. For statically managed PVs, this data must be provided by the user. For statically managed PVs this data must be provided by the user.
The following fields should be modified according to the volume that is imported:
spec.capacity.storage
: Should contain the size of the volume with suffix G (Gigabyte).
spec.nodeAffinity.required.nodeSelectorTerms.matchExpressions.values
: Must contain the Virtual Data Center ID from the Volume path.
Creating this PV will allow it to be used in Pod by referencing it in a PVC's spec.volumeName
.
A cluster autoscaler is a tool that automatically adjusts the size of the Kubernetes cluster when one of the following conditions is true:
There are pods that failed to run in the cluster due to insufficient resources.
There are nodes in the cluster that have been underutilized for an extended period of time, and their pods can be placed on other existing nodes.
The cluster autoscaler increases the node pool if pods cannot be scheduled due to a lack of resources. In addition, adding a node (from the node pool that needs to be increased) should provide a remedy for the situation. If there are no node pools that provide enough nodes to schedule a pod, the autoscaler will not enlarge.
The cluster autoscaler reduces the node pool if a node is not fully utilized for an extended period of time. A node is underutilized when it has a light load, and all of its pods can be moved to other nodes.
Yes, only node pools with active autoscaling are managed by the autoscaler.
No, the autoscaler cannot increase the number of nodes in the node pool above the maximum specified by the user or decrease it below the specified minimum. In addition, the quota for a specific contract cannot be exceeded using the autoscaler. The autoscaler cannot reduce the number of nodes in the node pool to 0.
All components installed in the cluster are updated. This includes the K8s control plane itself, CSI, CCM, Calico, and CoreDNS . With cluster maintenance, several components that are visible to customers are updated and reset to our values. For example, changes to CoreDNS are not permanent and will be removed at the next maintenance. It is currently not possible to set your own DNS records in the CoreDNS configuration, but this will be possible later.
Managed components that are regularly updated:
The maintenance time window is limited to four hours for Public and Private Node Pools. If all of the nodes are not rebuilt within this time, the remaining nodes will be replaced at the next scheduled maintenance. To avoid taking more time for your updates, it is recommended to create node pools with no more than 20 nodes.
If old nodes are replaced with new ones during maintenance, the new nodes will subsequently have different or new public IP addresses. You can pre-specify a list of public IP addresses from which entries for new nodes are taken. In such a way, the list of possible host addresses is limited and predictable. For example, to activate them differently through a whitelist.
The Kubernetes cluster control plane and the corresponding node pools can have different versions of Kubernetes. Node pools can use older versions than the control plane, but not vice versa. The difference between the minor versions must not be more than 1.
There is a distinction between patch version updates and minor version updates. You must initiate all version updates. Once initiated, the version updates are performed immediately. However, forced updates will also occur if the version used by you is so old that we can no longer support it. Typically, affected users receive a support notification two weeks before a forced update.
The Kubernetes API is secured with Transport Layer Security (TLS). Traffic between the nodes and the control plane is secured by mutual TLS, which means that both sides check whether they are talking to the expected remote station.
If clusters or node pools are created or modified, the operation may fail, and the cluster or node pool will go into a Failed status. In this case, our team is already informed because we monitor it. However, sometimes it can also be difficult for us to rectify the error since the reason can be a conflict with the client's requirements. For example, if a LAN is specified that does not exist at all or no longer exists, a service update becomes impossible.
The IONOS Kubernetes currently does not support the usage of your own CAs or your own TLS certificates in the Kubernetes cluster.
You can reserve Public Node Pools in multiple locations in the same cluster. This allows simple geo-redundancy to be configured and implemented. The control plane is geo-reserved (within Germany). There are several replicas running in different locations.
If a node is unavailable, like too many pods are running on it without resource limits, it can be replaced. To do this, you can use the following API endpoint:
A Private Node Pool ensures that the nodes are not connected directly to the internet; hence, the inter-node network traffic stays inside the private network. However, the control plane is still exposed to the internet and can be protected by restricting IP access.
Clusters and node pools turn yellow when a user or an automated maintenance process initiates an action on the resources. This locks the clusters and node pool resources from being updated until the process is finished, and they do not respond during this time.
Kubernetes clusters only support public networks only if they are VMs but not LAN networks.
Yes, if your node pool is configured to have a network interface in the same network as the VMs that you want to access, then you can add nodes.
Public Node Pools within a Kubernetes cluster are configured by defining a public dedicated node pool. Networking settings are specified to include public IP addresses for external access.
Private Node Pools within a Kubernetes cluster are configured by ensuring that each node in a pool has a distinct private network, while nodes within the same pool share a common private network.
It is crucial to set up these node pools with a network interface aligned with the network of the intended VMs when adding nodes to Kubernetes clusters.
No, the private NAT Gateway is not intended to be used for arbitrary nodes.
The Public Node Pools support the LoadBalancer service type. However, the Private Node Pools currently do not support the LoadBalancer service type.

Managed Kubernetes clusters for Private Node Pools are bound to one region. When you create a node pool, you need to provide a data center, which has to be in the same location as defined in the cluster. You can create Private Node Pools only in a see that shares the region with the managed Kubernetes cluster.
Kube-controller-manager manages controllers that provide functionalities such as deployments, services, etc. For more information, see .
The API server is a component of the Kubernetes control plane that exposes the Kubernetes API. The API server is the front end for the Kubernetes control plane. Kube-apiserver is designed to scale horizontally. It scales by deploying more instances. You can run several instances of kube-apiserver and balance traffic between those instances. For more information, see .
Kube-scheduler distributes pods to nodes. Pods must be created with resource limits so that nodes are not over-commissioned. For more information, see .
The hidden control plane is deployed on Virtual Machines (VMs) running in a geo-redundant cluster in the area of Frankfurt am Main, Germany. For more information, see and .
The Managed Kubernetes clusters have a Calico CNI plugin. Its primary function is to automatically assign IP addresses, set up network interfaces, and establish connectivity between the pods. Calico also allows the use of network policies in the Kubernetes cluster. For more information, see and .
The driver runs as a deployment in the control plane to manage volumes for Persistent Volume Claims (PVCs) in the IONOS Cloud and to attach them to nodes.
The soft mount option is required when creating PersistentVolume
with a source in Kubernetes. It can be set in the mount options list in the PersistentVolume
specification (spec.mountOptions
) or using the annotation key volume.beta.kubernetes.io/mount-options
. This value is expected to contain a comma-separated list of mount options. If none of them contains the soft mount option, the creation of the PersistentVolume
will fail.
The use of the annotation is still supported but will be deprecated in the future. For more information, see .
IONOS Cloud volumes are represented as resources in Kubernetes. The PV determines what happens to the volume when the PV is deleted. The Retain
reclaim policy skips deletion of the volume and is meant for manual reclamation of resources. In the case of dynamically provisioned volumes, the CSI driver manages the PV; the user cannot delete the volume even after the PV is deleted.
The PV has that ensure that Cloud resources are deleted. The finalizers are removed by the system after Cloud resources are cleaned up, so removing them prematurely is likely to leave resources behind.

If the node is in a NotReady state, and there is not enough RAM or the node runs out of the RAM space, an infinite loop occurs in which an attempt is made to free the RAM. This means the node cannot be used, and the executables must be reloaded from the disk. The node is busy with disk Input/Output (I/O). In such a situation, we recommend doing resource management to prevent such scenarios. For more information, see .
A is required to enable outbound traffic between the cluster nodes and the control plane. For example, to be able to retrieve container images.

The IONOS Cloud Container Registry is a universal repository manager with a recommended service for storing and managing custom container images and other artifacts in IONOS Cloud. Deploying and pulling images can be done using the Docker CLI or added directly to a Kubernetes deployment.
The IONOS Cloud Container Registry provides users with a dedicated registry or multiple registries based on their contracts, allowing them to host their own Docker images without the need for an external provider (such as Docker Hub).
A container registry is created to store and share custom images in the same regions where you deploy them. Container Registry is a high-performance platform for storing custom image containers. It can be used as part of CI/CD workflows for container workloads.
You can order and manage the Container Registry through the API. The API will allow integration into the Data Center Designer (DCD).
The IONOS Cloud Container Registry allows you to manage compatible registries by offering the following:
An authenticated registry where OCI-compliant artifacts (including Docker container images) can be stored and retrieved.
Access via the Public Internet and secure by requiring authentication to view, push, or pull images. The Container Registry is maintained by IONOS Cloud on your behalf, which means that our experts will apply non-stop patches to the underlying infrastructure and Container Registry software.
All images stored in the container registry are encrypted at rest.
Each container registry can have many repositories.
The IONOS Cloud Container Registry specifications are as follows:
Our platform is responsible for providing the operations required to facilitate the distribution of images.
The container registry is accessible from the public internet and maximally available (High availability setup) for pushing and pulling artifacts.
The service is managed, including any components on which it is built.
It also supports authentication tokens for use by robot accounts to be able to integrate into an automated CI/CD pipeline. You can create a one-time token to allow the CI/CD pipeline to push a new image.
It is possible to use the same credentials to access all registries and repositories in the same IONOS Cloud account that the user has access to.
All data in the registry will be encrypted at rest.
The IONOS Cloud Container Registry is available in the FRA region.
The IONOS Container Registry offers the following benefits:
create a registry access token with limited or unlimited permissions
create a temporary registry access token with limited or unlimited permissions
support for docker tools
login to registry
push an image
pull an image
delete an image
Note: The network traffic is not charged.
There are the following few limitations when working with IONOS Container Registry APIs:
You cannot choose your encryption keys (Trust-No-One) when encrypting data at rest; the Container Registry platform manages the keys.
It is not possible to grant repository access permissions to push, pull, or delete from a specific repository.
Any unauthenticated user will not be able to access the registry contents.
Prerequisites: Make sure you have the appropriate permissions. Only contract administrators, owners, and users with the Manage Registry permission can create a Container Registry.
1. In the DCD, go to Menu > Containers > Container Registry.
2. In the Container Registry Manager, click Add a Registry to start creating a new container registry.
3. Provide an appropriate Name.
Note:
It is not possible to change the registry name later.
The registry name:
must be globally unique across all customers.
must contain only alphanumeric characters and dashes.
must be between 3 and 63 characters in length.
must begin with an character between a-z.
must end with an alphanumeric character.
4. Choose the Location where you want your container registry to be run and the artifacts to be stored from the drop-down list.
Note: It is not possible to change the Location later.
5. Turn on the Vulnerability Scanning toggle so that your Container Registry is created with the vulnerability scanning enabled.
Note: We recommend that you create your Container Registry with Vulnerability Scanning enabled.
Vulnerability Scanning gives you the benefit of all artifacts being scanned for CVEs when pushed into a Container Registry and every time CVE databases are updated with newly identified CVEs. It is possible to add Vulnerability Scanning to a Container Registry. Once Vulnerability Scanning is enabled, it cannot be disabled later.
6. Click Add Registry. Your Container Registry and storage will be created.
Result: Your Container Registry is ready to use when its status is updated to Running.
Specification | Status |
---|
The container registry supports the , which allows it to be integrated into an automated CI/CD pipeline.
You can use the registry with compliant tools, e.g. .
For more information, see .
Docker Registry | Yes |
Built-in CI/CD | The container registry supports the Docker Registry HTTP v2 API, allowing it to be integrated into an automated CI/CD pipeline. |
Built-in OSS Vulnerability Scan | No |
Each Container Registry can provide a detailed detailed analysis of Common Vulnerabilities and Exposures (CVEs) that may be exploitable in your artifacts. For more information, see Enable Vulnerability Scanning.
Vulnerability scan results provide detailed information about the security of your artifacts at different levels. The following sections provide more information.
When new vulnerabilities are identified, you may want to search your entire Container Registry to see if any of the artifacts are vulnerable. To do this, you will need the Common Vulnerabilities and Exposures (CVE) number. Every published vulnerability or security issue is assigned a unique CVE number.
1. In the DCD, go to Menu > Containers > Container Registry.
2. In the Container Registry Manager, select the Container Registry that you want to search, and click on the Vulnerability Search section.
3. Enter the full CVE number of the vulnerability you want to search for.
Result: A list of artifacts known to be vulnerable to the CVE are displayed.
To ensure that your artifacts, and the software supply chain they rely on, remain secure, you will need to review the results of the vulnerability scan periodically. The first step in this review process will be to see which repositories contain vulnerabilities.
1. In the DCD, go to Menu > Containers > Container Registry.
2. In the Container Registry Manager, select the Container Registry that you want to review.
Result: You will see a list of repositories in the registry. The VULNERABILITIES column shows you the highest severity vulnerability in the last artifact pushed to the repository.
Note: Depending on the content of your registry, there may be too many repositories to list on a single page. Remember to use the per page to set the number of repositories displayed per page and to navigate between pages using < and >.
You can review which artifacts in a specific repository are exposed to vulnerabilities. This approach will show you which artifacts have known fixes, as well as when that artifact was last pushed (that is, when updates have been made) and when they were last pulled, this often aligns with software being deployed to an environment.
1. In the DCD, go to Menu > Containers > Container Registry.
2. In the Container Registry Manager, select the Container Registry that you want to review.
3. Select the repository that you want to review.
Result: You can now see all artifacts in the repository listed by artifact and displaying the following:
the tag used when pushing the artifact to the repository.
the VULNERABILITIES column shows you the highest severity vulnerability in the artifact at the time of the LAST SCAN.
the LAST PUSH date and time.
the LAST PULL date and time.
Note: Depending on the content of your repository, there may be too many artifacts to list on a single page. Remember to use per page to set the number of artifacts displayed per page and to navigate between pages using < and >.
1. In the DCD, go to Menu > Containers > Container Registry.
2. In the Container Registry Manager, select the Container Registry that you want to review.
3. Select the repository that you want to review.
4. Select the artifact you want to view.
Result: You can now see a list of all known CVEs that the artifact is vulnerable to.
You can filter the list by SEVERITY.
You can filter the list to only show those vulnerabilities that are reported as FIXABLE.
When you have found a specific CVE, either by viewing vulnerability scan results for a specific artifact or by finding artifacts that are vulnerable to a specific CVE, you can see more details about the CVE by clicking on the CVE identification number. This will provide additional information about the vulnerability and may include references to third-party sites where additional information can be found.
Each Container Registry has an option to configure the Garbage Collection schedule. By default, Garbage Collection is disabled because each customer should choose a schedule based on their needs.
Note: The container registry is read-only during the Garbage Collection to perform a complete analysis without changing the repositories.
Garbage Collection frees up storage space for layer data that are no longer referenced. It optimizes the volume of storage needed for each Container Registry and is necessary if all your artifacts use the same base operating system. Each layer can be referenced by more than one artifact. Hence, Garbage Collection ensures that other artifacts do not reference the layers before deletion.
The duration of the Garbage Collection will increase based on the volume of deleted repositories or tags and the total number of repositories and tags to be checked.
Note: Container Registries cannot immediately reduce storage usage when deleting artifacts or repositories.
Garbage Collection ensures the registry maintains data integrity while periodically cleaning up unused storage to optimize resource utilization.
1. In the DCD, go to Menu > Containers > Container Registry.
2. In the Container Registry Manager, select the Container Registry you want to configure.
3. Click > on the right of the Garbage Collection schedule in the Properties section.
4. Select the Day(s) and Time(UTC) to run the Garbage Collection on a weekly basis and click Update Schedule.
Note: You can configure it via the API for more granular and customized control over the Garbage Collection schedule.
Tokens manage access to your Container Registry effectively and efficiently. Tokens serve as secure authentication methods, eliminating the need for personal credentials to be used during Continuous Integration and Continuous Deployment (CI/CD) processes. Personal credential management can become cumbersome and impractical as your services and deployments expand. Tokens provide a scalable solution for access control.
In order to minimize the permissions given to each token, you can also use:
Scopes to limit token access as narrowly as possible to specific resources and the actions it is permitted to perform on those resources to enhance security during artifact deployment. Each token can link to an individual or service, simplifying the audit process and strengthening the ability to monitor registry activity.
Expiration dates to ensure that the permissions of tokens can be automatically revoked after a period of time.
Distinct tokens for each environment to ensure access appropriately aligns with each environment's requirements and your security policies.
1. In the DCD, go to Menu > Containers > Container Registry.
2. In the Container Registry Manager, select the Container Registry that you want to configure.
3. Click Add Token in the Tokens tab to create a new Token
4. Provide the following details:
Name: Enter a Name for the token. It is a user-visible name making it simple to recognize the token.
Notes:
It is not possible to change the token name later.
The registry name:
must contain only alphanumeric characters and dashes.
must be between 3 and 63 characters in length.
must begin with an character between a-z.
must end with an alphanumeric character.
Status: Turn on the toggle button to enable the status. The token can be disabled later.
Expiry Date: Select Expire on (minimum 1 hour) to enter an expiry date. Otherwise, select No expiry.
Note: The Expiry Date must be at least one hour in the future. When the Expiry Date is reached, the token is deleted, it is not disabled.

IONOS's Database as a Service (DBaaS) consists of fully managed databases, with high availability, performance, and reliability hosted in IONOS Cloud and integrated with other IONOS Cloud services.
We currently offer the following database engines:
IONOS DBaaS lets you quickly set up and manage MongoDB database clusters. Using IONOS DBaaS, you can manage MongoDB clusters, along with their scaling, security and creating snapshots for backups. The feature offers the following editions of MongoDB to meet your enterprise-level deployments: Playground, Business, and Enterprise. For more information, see Overview.
IONOS DBaaS gives you access to the capabilities of the PostgreSQL database engine. Using IONOS DBaaS, you can manage PostgreSQL cluster operations, database scaling, patch your database, create backups, and security.
With the help of IONOS DBaaS, you may use the functionalities of the MariaDB database engine to scale database resources in the cloud flexibly, improve security, patch the database, and provide redundancy and backups.
In the DCD > Databases, the database resources allocated as per your user contract are displayed in the Resource Allocation. The resources refer to the Postgres Clusters, MongoDB Clusters, MariaDB Clusters, CPUs, Cores, RAM, and Storage databases quota:
16 CPU Cores
32 GB RAM
1500 GB Disk Space
10 database clusters
5 nodes within a cluster
Note: A single instance of your database cluster cannot exceed 16 cores and 32GB RAM.
You can view the number of resources that are available and can be used, as well as the number of resources already consumed. Based on the resources available here, you can allocate resources during the creation of a database cluster. For resource allocation, contact IONOS Cloud Support.
IONOS Cloud Container Registry is a managed service that provides users with a dedicated Docker registry or multiple registries as part of their contract. This enables them to host their own Docker images without the need for an external provider (such as Docker Hub).
IONOS Container Registry is totally private and requires authentication to access it. It resides in the same infrastructure as your other IONOS Cloud infrastructure. Any unauthenticated user will not be able to access the registry contents. IONOS Container Registry software is always up-to-date and resilient. You don't need to use mK8s capacity to run and then manage your Container Registry.
Following are a few limitations for the IONOS Container Registry:
You cannot choose your encryption keys (Trust-No-One) when encrypting data at rest; the Container Registry platform manages the keys.
An unauthenticated user will not be able to access the registry contents.
To have a registry, you need authentication and authorization, and the registry's contents must not be accessible to unauthenticated users.
All container registries are available on the public internet but cannot be accessed without a token with the correct rights.
Vulnerability scanning is an add-on feature for your container registry that analyzes known software in your container images against known security vulnerabilities (or CVEs) that may put your infrastructure, applications or data at risk.
CVE stands for Common Vulnerability and Exposure Report, which lists disclosed information regarding security vulnerabilities in publicly released software.
We review multiple sources of information for any given CVE. These sources may independently score the risk differently. Hence, we constantly expose the highest score reported by the sources.
The Common Vulnerability Scoring System (CVSS) is used for calculating the severity of a CVE based on many factors (base, temporal and environmental).
CVSS assessment produces a number between 0-10. With 10 being the most severe rating. A CVSS qualitative rating systems helps simplify CVE severity classification, as follows:
0.0 None
0.1 - 3.9 Low
4.0 - 6.9 Medium
7.0 - 8.9 High
9.0 - 10.0 Critical
The threat landscape is ever-changing, and we cannot guarantee that all vulnerabilities are detected.
New CVEs are published constantly, existing CVEs may be revised over time, either increasing or decreasing in severity.
The threat landscape is ever-changing. New vulnerabilities are identified in software constantly, but only when they are publicly published can they be detected in your images.
Vendors and security researchers may choose not to announce certain vulnerabilities and exploits when they are first identified. This is usually the case if the vulnerability is particularly easy to exploit and is of high consequence. This gives software vendors time to analyze and fix or mitigate the issue.
Sometimes, a CVE may show up in your reports as being fixable. It means that the affected software is vulnerable only in specific versions of a package; the vendor may have released an updated version that fixes the vulnerability, or there may be other mitigations that the software vendor suggests to limit or negate the vulnerability.
At certain times, there may be no fix or mitigation available. In these situations, analysis of the risk and awareness can assist with managing information security risks your business is exposed to.
The vulnerability scanning service monitors for changes in published CVE reports. Images held in your registry that have been pushed or pulled recently (in the past 30 days) are rescanned as new information on vulnerabilities becomes available.
This also means that your vulnerability reports will be updated to reflect criticality changes if a vulnerability is reclassified. For example, if a particular vulnerability is downgraded in severity from Critical to High, your reports will be updated to reflect this.
Not all containers and their packages can be scanned successfully. If your image shows a Last Scan time and Unknown vulnerability status, the scanning engines may be unable to process the image. We monitor for these situations and regularly review the scanning techniques to ensure these are kept to a minimum.
In some cases, an image may display an Unknown vulnerability status and lack a Last Scan time. This can occur when the repository name is less than two characters long or exceeds 255 characters. While it's technically allowed to name a repository with just a single character, such names don't fulfil the requirements of the scanning engine. To address this issue, push your image again using a repository name that falls within the range of 2 to 255 characters in length.
It is also possible that the scanning of your container may still need to be completed. If your vulnerability report for an image does not show the Last Scan time, check again later when the scanning is complete.
Typically, scanning an image takes only a few seconds, but this depends on many factors, such as the size of the image, the number of layers, and the number and types of packages installed.
Yes, vulnerability scanning is non-blocking, and your image may be pulled at any time.
Maintaining good container hygiene practices helps to reduce your exposure.
Ensure that your container build process updates OS system packages for your container.
Regularly rebuild and redeploy your container images
Reduce your surface area—Analyze your images and include only the software and libraries required for your application to function.
Change your base image—In some cases, switching to a different base image may help. Example: Alpine.
Consider distroless/scratch images for your bases.
Review your supply chain when using third-party dependencies.
Lots of software installation guides recommend using curl-pipe-bash
.
Example: curl https://source-reposotory.tld/install.sh | bash
We recommend that you avoid this method. You may review the install.sh
script at the first build, but if a malicious actor can modify that script later, your container build could be compromised.
No, container vulnerability scanning is a read-only operation. The content of your image remains unchanged.
With IONOS Cloud , you can quickly set up and manage the MariaDB database engine. You can use the database engine's features, such as the flexible cloud-based scaling of the database resources, patching the database, creating backups and redundancy, and enhancing security with IONOS DBaaS.

Single-node cluster: A single-node cluster only has one "primary node". This node accepts customer connections and performs read and write operations. It is a single point of truth and a single point of failure.
Multi-node cluster: A multi-node cluster contains one "primary node" and one or more "secondary nodes" replicating data from the primary node. The secondary nodes always attempt to keep up-to-date with the primary, but they may lag due to the asynchronous replication. If the current primary node fails, a secondary node elevates to the primary node. The old primary node is automatically fixed and turned secondary.
You can scale the existing database clusters using "horizontal" and "vertical" scaling.
Horizontal scaling is defined as configuring the number of nodes that run in parallel. You can increase or decrease the number of nodes in a cluster.
Scaling up the number of nodes does not cause a disruption. However, decreasing may cause a switchover, if the current primary node is removed.
Note: This method of scaling is used to provide high availability. It will not increase the database performance.
Vertical scaling refers to configuring the size of the individual nodes to process more data and queries. You can change the number of cores and the memory size to have the configuration you need.
During scaling, the existing nodes in a cluster are modified after being turned off. In the event of scaling up or down, the downtime is minimal when there are multiple nodes, as the secondary nodes are modified first, followed by the resources. After the modification is complete, the primary node is switched automatically over to a secondary node and the connection is established.
For a single-node cluster, you may expect downtime before the Virtual Machine (VM) restarts because the node is modified in place.
Warning: The connection to the database will be terminated if it is connected to an application. Additionally, all ongoing queries will be aborted causing disruption. Hence, we recommend that you perform scaling outside of peak hours.
You can also increase the size of storage. However, it is not possible to reduce the size of the storage, nor can you change the type of storage. Increasing the size is done on the fly and causes no disruption.
The synchronization_mode
determines how transactions are replicated between multiple nodes before a transaction is confirmed to the client. IONOS DBaaS supports only the asynchronous (default) replication mode for MariaDB, wherein the first transaction commit is always on the master, followed by replication to the standby node(s).
Asynchronous replication sends a transaction confirmation back to the user immediately after the transaction is written to disk on the primary node without waiting for the standby. Replication takes place in the background. The cluster can lose some committed (not yet replicated) transactions during a failover to a secondary node in an asynchronous mode. The performance penalty of asynchronous replication depends on the workload.
MariaDB uses an asynchronous replication mechanism. The primary node's binary log needs to be enabled to save data and make structural changes in the binary log. For more information, refer to the MariaDB Documentation.
Warning: You may lose your data if the server crashes while your data is pending replication.
Please note that the synchronization mode can impact DBaaS in several ways:
Aspect | Asynchronous |
---|---|
Primary failure
A healthy standby will be promoted if the primary node becomes unavailable.
Standby failure
No effect on primary. Standby catches up once it is back online.
Consistency model
Strongly consistent except for lost data.
Data loss during failover
Non-replicated data is lost.
Data loss during primary storage failure
Non-replicated data is lost. Because replication is asynchronous, it is possible that the secondary primary has not yet received all events in the case that the active primary crashes.
Latency
Limited by the performance of the primary node.
ACID Compliance: MariaDB ensures data integrity and reliability through the support of Atomicity, Consistency, Isolation, and Durability (ACID) properties.
Triggers and Stored Procedures: MariaDB allows the creation of database triggers to automatically perform actions based on specified events and stored procedures for executing sets of SQL statements.
User Management and Security: Database access can be restricted to authorized users only. Role-based access control, robust encryption support, and user management tools ensure secure access and data protection.
Indexes and Storage Engines: MariaDB supports various types of indexes to enhance query performance. In addition, it supports storage engines such as InnoDB, MyISAM, and Aria, thus offering flexibility and performance optimization for different use cases.
Query Optimizer and Performance Tuning: MariaDB's query optimizer and performance tuning capabilities help improve database efficiency and query execution speed.
Full-Text Search: Integrated full-text search support enables efficient and flexible text searching within large volumes of data.
Data Compression: Data compression techniques reduce storage requirements and improve query performance.
Columns Support:
Virtual (Computed) Columns enable column definitions based on expressions, thus enhancing data retrieval capabilities.
Dynamic Columns capability allows storing different column sets for each row, thus enabling flexible schema design.
Transactional Support: Comprehensive transaction support, allowing complex operations with rollback capabilities for data integrity.
SQL Support: Full support for standard SQL and JSON functionalities, facilitating seamless integration with existing applications and tools.
Upgrades: IONOS DBaaS supports user-defined maintenance windows with minimal service disruption. The database may be unreachable for a few seconds when necessary for restarts or switching to another replica. Single-node clusters temporarily gain a second node when it is necessary to replace the old one. Hence, maintenance downtime is the same for multi-node and single-node clusters.
Backups: Base backups are carried out daily, with Point-in-Time recovery for one week, ensuring data integrity and quick recovery in case of data loss.
Database Monitoring and Reporting: MariaDB provides tools for performance monitoring, query analysis, and reporting to help optimize database usage and identify potential issues.
Easy Configuration: Configure your MariaDB instance in compliance with IONOS DBaaS's specifications. You can quickly create databases and tables, define user roles, and assign permissions similar to a physical database using SQL commands, IONOS's graphical interface, or API commands.
Scalable: Because of MariaDB's horizontal scalability, new nodes, storage, memory, and cores may be added to match the growing demand for greater processing power for data.
High availability: Automatic node failure handling for multi-node and single-node clusters.
Security: The communication between clients and databases is secured using TLS for secure data transmission if your MariaDB database is set up to use it.
Programmatic Resource Management: Easy deployment and management in cloud environments through APIs, SDKs, and configuration management tools.
Resources: It is offered on Enterprise VM, with a dedicated CPU, storage, and RAM. Currently, SSD is the only supported storage option for MariaDB.
Network: DBaaS supports private LANs only.
JSON and GIS Support: Effectively storing and querying spatial data and JSON documents is possible with native support for Geographic Information System (GIS) and JSON functions.
IONOS DBaaS for MariaDB is fully integrated into the Data Center Designer and has a dedicated API. You may also launch it via automation tools like Ansible and Terraform.
MariaDB is a reliable, scalable, and secure Relational Database Management System (RDBMS). IONOS DBaaS assures the configured database is automatically provisioned, thus saving time and ensuring your business runs smoothly without disruption. DBaaS gives you access to the capabilities of the MariaDB database engine, ensuring you can use the same code, applications, and tools you already use in your existing databases with DBaaS.
You can order a cluster of multiple redundant nodes with automatic failover for high availability. For more information, see High Availability and Scaling.
The IONOS DBaaS for MariaDB automatically creates and stores backups of your MariaDB content regularly, which is capable of a point-in-time restore. Backups happen automatically to reduce your workload further and ensure that you can swiftly resume operations in the event of a failure.
It is mandatory to specify a periodic maintenance time window for regular maintenance. During the maintenance time window, you may encounter a short, occasional downtime, typically caused by restarting the MariaDB or switching to another replica.
The illustration shows how MariaDB can be created and managed using IONOS DBaaS.
As shown in the illustration, you can order and manage a MariaDB database cluster using the DCD or the corresponding API. Simultaneously, you can choose the LAN, the VDC, and the IP address on which the MariaDB should be available. The IONOS Cloud DBaaS Backend provisions the MariaDB cluster according to your request. The primary instance of the MariaDB cluster will be available on your LAN within the VDC and on the chosen IP address after provisioning.
IONOS Cloud supports "MariaDB Long-Term Support (LTS) versions" (example: 10.6, 10.11), starting from MariaDB 10.6.
The IONOS Cloud DBaaS takes care of minor version upgrades during maintenance windows, for example, from 10.11.6 to 10.11.7. For more information, see Upgrade and Maintenance.
DBaaS for MariaDB is offered in all IONOS Cloud locations. You can use DBaaS instances running MariaDB in the IONOS Cloud infrastructure. For more information about the regional API endpoints, see Endpoint.
A MariaDB cluster comes with an x509 certificate for Transport Layer Security (TLS). You can enforce this transport encryption with the client option --ssl-verify-server-cert
.
The requested disk space stores all the data that MariaDB is working with, including database logs and binary log files. Each MariaDB instance contains storage of the configured size. IONOS manages and stores the applications and operating system independently from the configured storage.
MariaDB rejects further write requests if the disk exceeds the storage limit. Ensure that you order enough storage to keep the MariaDB cluster operational. You can monitor the storage utilization in the DCD.
You can also verify if the tables are oversized. For more information, refer to the . Bloated tables can consume space, so we recommend diagnosing the cause and reclaiming the free space. For more information, see .
Database log files and binary log files are stored on the same disk as the database. DBaaS deletes older log files automatically with the expire_logs_days
in a typical operation mode. The older files are deleted after a retention period of seven days. For more information, refer to the .
For administrative reasons, automatic switchovers happen in a controlled, planned manner during the scheduled maintenance. However, data is preserved during a switchover.
During a switchover, the IP address of the primary server is moved to the promoted replica server. Meanwhile, the client is signaled about the switchover by closing the TCP connection on the server. The client automatically closes the connection and reconnects to the database.
IONOS DBaaS MariaDB has an automatic failover enabled by default. A failover can occur when the primary node fails. As a result, one of the replicas is chosen and promoted to be the new primary node. When the old primary node returns, it is added as a replica to the cluster.
Note: You may lose the data if it is not replicated but only committed to the primary node.
MariaDB supports both automatic and manual backups. Automatic backups are created in either of the following instances:
During the creation of a cluster.
Upon upgrading the current version of MariaDB to a higher version.
When a Point-In-Time-Recovery operation is conducted.
Note: IONOS maintains backups for the last seven days so that you can recover them for up to a week.
IONOS, by default, performs automatic backups, which are full backups that run regularly at a specific hour based on the value set in the DBaaS component.
IONOS facilitates the "logical" backup option using mariadb-dump
. Alternatively, you can also use the mariadb-dump
client to back data to a different location. For more information, refer to the MariaDB Documentation.
IONOS Cloud does not allow superuser access to MariaDB services. However, most DBA-type actions are still available through other methods.
All back-end tasks necessary to keep your database operating at peak efficiency are handled by our platform. You can perform the following:
Database installation via the DCD or the DBaaS API.
Pre-set database configuration and configuration management options.
Automated backups for seven days.
Regular patches and upgrades during maintenance.
Disaster recovery via automated backup.
Service monitoring both for the database and the underlying infrastructure.
Tasks related to the optimal health of the database remain your responsibility. These include:
Optimization
Organizing data
Creating of indexes
Updating statistics
Consultation of access plans to optimize queries
Learn how to set up a MariaDB cluster.
Learn how to view the list of MariaDB clusters.
Learn how to delete a MariaDB cluster.
Before setting up a database, ensure that you are working within a provisioned Virtual Data Center (VDC) that contains at least one VM from which to access the database. The VM you create is counted against the quota allocated in your contract.
Database Manager is available only for contract administrators, owners, and users with Access and manage DBaaS privileges. You can set the privilege via the DCD group privileges. For more information, see Manage User Access.
To create a MariaDB cluster, follow these steps:
Log in to the DCD with your username and password.
Go to Menu > Databases > MariaDB.
Info: The MariaDB cluster overview section displays the resources allotted to your contract and the number of used and unused resources.
Click Create cluster to create a new MariaDB cluster.
Enter the following details in the Create cluster window:
Result: The Estimated costs will be displayed based on the input. It is exclusive and certain variables like traffic and backup are not considered.
Click Save to create the MariaDB cluster.
Result: Your MariaDB Cluster is now created.
To define cluster properties, specify the following:
Cluster Name: Enter an appropriate name for your MariaDB cluster.
Cluster Version: Select a version of MariaDB from the drop-down list. IONOS only supports Long-Term Support (LTS) versions, starting from MariaDB 10.6.
Instances: Enter the number of MariaDB nodes you want in the cluster. One MariaDB node always manages the data of exactly one database cluster. You can also use the arrows to increase or decrease the number of nodes. Replication is possible only when you define more than one node.
Note: Here, you will have a primary node and one or more standby nodes that run a copy of the active database, so you have n-1 standby nodes in the cluster.
Location: Select a location of your preference from the drop-down list.
Replication Type: The replication type is asynchronous by default for MariaDB. You will see this option only upon selecting more than one node (instance). In an asynchronous mode, the primary MariaDB node does not wait for a replica to indicate that the data has been written. The cluster can lose some committed transactions to ensure availability.
CPU Type: The CPU type is set to Dedicated Core, by default.
To select the number of resources that you want to associate with the MariaDB cluster, specify the following:
Number of CPUs (per instance): Increase or decrease the number of CPUs using the slider.
RAM Size (per instance): Increase or decrease the size of the RAM using the slider to suit your needs.
Storage Type: Currently, IONOS supports only SSD Premium, which is selected by default.
Storage Size: Enter the storage size, in Gigabytes (GB), either manually or use the arrows to increase or decrease the storage size accordingly based on your needs.
You can also click How to get the IP section on the right side to know how to retrieve an IP address.
Datacenter: Select a data center from the drop-down list to associate it with the MariaDB cluster. The available data centers in the drop-down list vary according to the chosen Location. For more information, see Define cluster properties.
Datacenter LAN: Select a LAN from the drop-down list for the data center.
Private IP: Enter the private IP or subnet using the available Private IPs.
Note: To know your private IP address/Subnet, you need to:
Create a single server connected to an empty private LAN and check the IP assigned to the respective NIC in the selected LAN. The DHCP in that LAN always uses a /24 subnet, so you must reuse the first 3 octets to reach your database.
To prevent a collision with the DHCP IP range, it is recommended to use IP addresses ending between x.x.x.3/24 and x.x.x.10/24 (which are never assigned by DHCP).
If you have disabled DHCP on your private LAN, you must discover the IP address on your own.
Your chosen start time (UTC) plus four hours is the maintenance time.
Day: Select a day from the drop-down list to set a day for maintenance.
Note: We recommend choosing the day and time appropriately because the maintenance occurs in a 4-hour-long window.
The credentials of any user who has previously been created in the backup will be overwritten.
Username: Enter a username to provide access to the MariaDB cluster for the respective user.
Password: Enter a password for the respective user.
Start Time UTC: Enter a time using the pre-defined format (hh:mm:ss) to schedule the maintenance task. You can also click the icon to set a time.
IONOS DBaaS MariaDB is a flexible database engine that is a perfect fit for facilitating enterprise-level analytics and solutions to drive online web applications for both individual use and business purposes. Due to its open-source nature, improved performance and MySQL compatibility, it is liked by developers and companies alike.
The price and overhead of managing voluminous data for businesses and individuals rise as the data increases.
MariaDB can be recommended for various instances where extensive data is stored and analyzed. Its high-availability environment ensures minimized downtime and continuous availability of data. Here are some scenarios where it can be implemented:
Web Applications: MariaDB is highly scalable, provides fast and reliable data retrieval, and can support sudden spikes in traffic. Hence, it can be used for web applications as a backend database, because it can handle the data storage needs of a dynamic website or web application.
Healthcare Systems: It is ideally suited for the secure and scalable storage and management of healthcare information, medical records, and patient data.
E-commerce Organizations: With its ability to manage user accounts, transactional data, and product catalogs, it is an ideal match for E-commerce platforms. Its ACID compliance ensures integrity and data consistency.
After creation, you can view the list of MariaDB clusters and delete them if they are no longer required.
To view a list of the clusters, follow these steps:
Log in to the DCD with your username and password.
Go to Menu > Databases > MariaDB.
Result: A list of all MariaDB clusters is displayed. You will see the following details:
NAME: Displays the name of the cluster.
STATE: Displays the state of the respective MariaDB cluster.
BUSY: When the cluster is in the creation mode or it is being updated.
AVAILABLE: When the cluster is available and healthy.
DESTROYING: When the cluster is being deleted.
FAILED: An error occurred.

INSTANCES: Displays the number of nodes.
VERSION: The version is set to 10.6 by default.
Details: Select Details: to view the details of the respective cluster.
Delete: Select Delete to delete the corresponding cluster. In the dialog box that appears, select Delete to confirm deletion. For more information, see Delete a MariaDB Cluster.
OPTIONS: Select to perform the following:
IONOS Cloud updates and patches your database cluster to achieve high standards of functionality and security. This includes minor patches for MariaDB and patches for the underlying operating system. Generally, these updates are unnoticeable and do not interrupt your operation. However, occasionally, IONOS restarts your MariaDB instance to allow the changes to take effect.
Prepare for a downtime during the version upgrade.
Ensure the database cluster has enough available storage. While the upgrade is space-efficient (because it does not copy the data directory), some temporary data is written to the disk.
Note: Updates to a new minor version are always backward compatible. Such updates occur during the maintenance window with no additional actions from the user.
Currently, MariaDB only supports minor upgrades. IONOS replaces the mariadb
executable binaries with those from a newer version, followed by the execution of the mariadb-upgrade
command.
The process replicates data from the old version to the new version and the database switches to the new version. For more information about the upgrade process, refer to the MariaDB Documentation.
All changes that may cause service interruption (like upgrades) are executed within the maintenance window, which is a weekly four-hour window. During the maintenance window, you may experience uncontrolled disconnections and an inability to connect to the database cluster. Such disconnections are destructive for any ongoing transactions and we recommend you reconnect. For more information about how to configure maintenance windows for MariaDB, see Set Up a MariaDB Cluster.
IONOS DBaaS stores the generated logs on the same disk as the database. Log files are rotated according to their size to conserve the disk space. Log messages are subject to a 30-day retention policy and are regularly checked to ensure they do not consume up to 175 MB of disk space.
Logs are generated for the following:
Connections established during a session creation
Disconnections when the session terminates
Lock wait time
DDL statements
Statements that run for at least 500 ms
Statements that result in an error
For more information, refer to the MariaDB Documentation.
Note: Currently, IONOS does not allow updating the log generation configuration.
MariaDB uses binary logs for continuous archiving and replication.
The binary logs record every change to the database. MariaDB deletes older log files automatically with the expire_logs_days
in a typical operation mode. It means that binary log files, regular database log files such as audit logs, error logs, and client logs are deleted. For more information, refer to the MariaDB Documentation.
Ensure that the client library is up-to-date and supports the mysql_native_password
authentication. For more information, refer to the MariaDB Documentation. The following links on the MariaDB website can help you with:
Authentication. For more information about resetting the database password, see Reset your Database Password.
All client connections are encrypted using TLS. To secure communications with the MariaDB Server using TLS, you need a private key and an X509 certificate for the server. Server certificates are issued by Let's Encrypt. For more information about certificates, refer to the MariaDB Documentation.
Certificates are issued for the DNS name of the cluster which is assigned automatically during creation and will look similar to ma-98tcp98ofe.qa.mariadb.fr-par.ionos.com
. It is available via the IONOS API as the dnsName
property of the cluster
resource.
Here is how to verify the certificate using MariaDB with ssl
option:
A regional endpoint is necessary to interact with the MariaDB REST API endpoints. For more information, see the API specification file.
IONOS supports the following endpoints for various locations:

After creating a database, you can access it via the corresponding LAN using the same username and password specified during creation.
This is the only opportunity to set the username and password via the API. The API does not provide a way to change the credentials yet. However, you can change them later using raw SQL.
The data center must be provided as a UUID. The easiest way to retrieve the UUID is through the Cloud API.
Note: The sample UUID is 498ae72f-411f-11eb-9d07-046c59cc737e
.
Your values will differ from those in the sample code. It may contain different IDs, timestamps etc.
You may have noticed that the metadata.state
is BUSY
and that the database is not yet reachable. This is because the cloud will create a completely new cluster and needs to provision new nodes for all the requested replicas. This process runs asynchronously in the background and might take up to 30 minutes.

After creation, remember to validate the status of your MariaDB cluster. For more information, see Verify the Status of a MariaDB Cluster.
To delete a MariaDB cluster, follow these steps:
Log in to the DCD with your username and password.
Go to Menu > Databases > MariaDB. A list of all MariaDB clusters is displayed.
Select Delete in the dialog box to confirm deletion.
Alternatively, you can also click the respective row to choose a MariaDB cluster that must be deleted and on the Details page, select x Delete cluster.
Result: The STATE of the respective MariaDB cluster is set to DESTROYING before it is completely deleted.
Click in the OPTIONS column and select Delete.
You can retrieve a list of MariaDB clusters and also specify the maximum number of elements to be returned by specifying an integer for limit
and defining the pagination using offset
.
Additionally, you can also use a response filter (filter.name
) to list only the MariaDB clusters that contain the specified name.
202 Successful operation
You may ensure the success of creating a MariaDB cluster by adhering to the network requirements and resource concerns outlined on this page. Furthermore, details regarding database backup are also available.
To set up a database inside an existing data center, you should have at least one server in a private LAN. You need to choose an IP address, under which the database leader should be made available.
There is currently no IP address management for databases. If you use your subnet, you may use any IP address in that corresponding subnet. You must choose the IP address of the subnet that IONOS assigns you if your servers use DHCP. The IP address of the subnet can be found in your NIC configuration.
CPU, RAM, storage, and number of database clusters are counted against quotas. For more information, see .
Database performance depends on the storage type. Currently, IONOS supports only storage type, by default.
The are stored alongside the database. The amount of files can grow and shrink depending on your workload. For a reasonable performance, we recommend that you set the SSD's storage size to at least 100 GB.
All database clusters are backed up automatically. For more information, see .
The database will be deployed in about five minutes after the creation of your first MariaDB cluster. For more information about creating a MariaDB cluster, see Create a MariaDB Cluster.
You can manually verify whether the create request is successful because the notification mechanism is not yet available. However, you can poll the API to see when the state
switches to AVAILABLE
. You can use the following command:
You can connect to your MariaDB cluster soon after its creation. For example, you can connect using the ssh
command as follows and the credentials that you set in the POST
request:
You can use the following command to set the environment:
Alternatively, you can use the following commands to connect to the database:
You can create additional users, roles, databases, and other objects via the SQL. These operations are highly dependent on your database architecture.
The PUBLIC
role is a special role in which all database users inherit the permissions. This is also important if you want to have a user without write permissions, since by default PUBLIC
is only allowed to write to the public
schema.
For more information about managing databases, refer to the MariaDB Documentation.
The CREATE USER
statement can be used to create one or more user accounts in the MariaDB database. Only users with the global CREATE USER
privilege or the INSERT
privilege for the MySQL database can create users. For more information, refer to the MariaDB Documentation.
Result: You now have a ready-to-use MariaDB cluster.

This topic describes connecting to MariaDB from your managed Kubernetes cluster.
Ensure that the following are available before connecting to the database:
A datacenter with the following id
: xyz-my-datacenter
.
A private LAN with id 3
using the network 10.1.1.0/24
.
A database connected to LAN 3
with the following IP address: 10.1.1.5/24
.
A Kubernetes cluster with the following id
: xyz-my-cluster
.
In this example, we use DHCP to assign IP addresses to node pools. Therefore, the database must be in the same subnet as the DHCP server.
To enable connectivity, follow these steps:
Connect node pools to the private LAN, which is connected to the database:
Note: It may take a while for the node pool to be ready.
Create a pod to test the connectivity. Schedule the pod exclusively for the node pools connected to the additional LAN if you have several node pools.
Alternatively, you can also use the following commands:
Create the pod: kubectl apply -f pod.yaml
Attach the pod and test connectivity:
Result: The database starts accepting connections.
You can retrieve a MariaDB cluster using its UUID. It is found in the response body when a MariaDB cluster is created or when you retrieve a list of MariaDB clusters using GET

A user's identity in MariaDB is determined by their username and host combination. If you have numerous users from different source hosts, you will need to reset the password for each user. To reset your database password, connect to the MariaDB cluster and run either of the following commands using the user whose password should be changed:
SET PASSWORD = PASSWORD('<new password>');
SET PASSWORD = '<passwordhash>';
Tables can become bloated during regular operation, meaning they consume more disk space than is required. The causes can be deletions or updating large amounts of data, resulting in the following:
The disk of the MariaDB cluster runs out of space.
MariaDB tables might be bloated.
To overcome the fragmentation of the tables, they have to be rewritten. This causes data to be stored in a physically optimal way. MariaDB stores the information about bloat in the data_free
column of information_schema.tables
.
Diagnose the problem by finding bloated tables. You can use the following query:
Warning: In particular, if there are numerous databases or tables in the instance, frequent querying from information_schema.tables
is expensive and, hence, should be avoided. Querying invokes heavy filesystem operations and can lead to substantial performance impacts during the execution of the query.
Note: When the table statistics are not up to date, the table size computation in information_schema.tables
may not work as expected, and the queries may display incorrect values for a particular table. You can use ANALYZE TABLE <tablename>
instead to sort the problem and refresh the table statistics.
When you use InnoDB Full-Text Search, it creates additional files, consuming added space on the filesystem, but does not show up in the information_schema.tables
. You can determine the size by querying information_schema.innodb_sys_tablespaces
.
Reclaim free space. You can follow the steps for InnoDB and MyISAM accordingly:
InnoDB To rewrite a InnoDB table, execute ALTER TABLE <table_name> ENGINE INNODB
or ALTER TABLE <table_name> FORCE
.
Warning: During the rewrite, the tables are blocked for writing access. To minimize the downtime, you can execute ALTER
with ALGORITHM=COPY, LOCK=NONE
.
For easy generation of all ALTER TABLE
statements, we recommend using the following SQL statement:
SELECT CONCAT('ALTER TABLE `', TABLE_SCHEMA, '.', TABLE_NAME, '` ENGINE InnoDB;') FROM information_schema.tables WHERE `TABLE_TYPE` = 'BASE TABLE' AND `ENGINE` = 'InnoDB'
MyISAM You can use the OPTIMIZE TABLE
command to rewrite a MyISAM table and reclaim all disk space from data_free
. Example: OPTIMIZE TABLE <table_name>;
While the OPTIMIZE TABLE
command is designed for the MyISAM storage engine to reorganize and optimize data files, it also supports InnoDB for compatibility reasons. Internally, when the command is executed but notices that the table uses InnoDB and not MyISAM, the command executes ALTER TABLE <table_name> FORCE
instead of manually optimizing the table.

The MongoDB Playground, MongoDB Business, and MongoDB Enterprise editions offer the following key capabilities:
Availability: Single instance database cluster with a small cube template availability.
Security: Communication between instances and between the client and the database cluster is protected with Transport Layer Security (TLS) using Let's Encrypt.
Resources: Cluster instances are dedicated Servers, with a dedicated CPU, storage, and RAM.
Backup: Backups are disabled for this edition. You need to upgrade to MongoDB Business or MongoDB Enterprise to avail database backup capabilities.
High availability: Multi-instance database clusters across different physical hosts with automatic data replication and failure handling.
Security: Communication between instances and between the client and the database cluster is protected with Transport Layer Security (TLS) using Let's Encrypt.
Management: Efficient monitoring and management are essential for maintaining the health and performance of MongoDB deployments. IONOS MongoDB Business Edition includes powerful monitoring and management tools to simplify these tasks. The MongoDB management enables centralized monitoring, proactive alerts, and automated backups, allowing businesses to efficiently monitor their clusters and safeguard their data.
Resources: Cluster instances are dedicated Servers, with a dedicated CPU, storage, and RAM. All data is stored on high-performance directly attached NVMe devices and encrypted at rest.
Backup: Daily snapshots are kept for up to seven days.
Restore: Databases can be restored from snapshots.
Shards: Supports horizontal scalability through MongoDB sharding, which allows for data to be distributed across multiple servers. For an example of how to create a sharded cluster, see Create a Sharded Database Cluster.
Resources: Cluster instances are Virtual Servers with a boot and a data volume attached. The data volume is encrypted at rest.
BI Connector: The MongoDB Connector for BI allows you to query MongoDB data with SQL using tools such as Tableau, Power BI, and Excel. For an example of how to create a cluster with a BI Connector, see Enable the BI Connector.
Network: Clusters can only be accessed via private LANs.
High availability: Multi-instance clusters across different physical hosts with automatic data replication and failure handling.
Security: Communication between instances and between the client and the cluster is protected with Transport Layer Security (TLS) using Let's Encrypt.
Backup: Daily snapshots are kept for up to seven days.
Restore: Databases can be restored from a specific snapshot given by its ID or restored from a point in time given by a timestamp.
Offsite Backup: Backup data is stored in a location other than the deployed database cluster.
Enterprise Support: With MongoDB Enterprise, you gain access to professional support from the MongoDB team ensuring that you receive timely assistance and expert guidance when needed. IONOS offers enterprise-grade Service Level Agreements (SLAs), guaranteeing rapid response times and 24/7 support to address any critical issues that may arise.
Note: IONOS Cloud does not allow full access to the MongoDB cluster. For example, due to security reasons, you cannot use all roles and need to create users via the IONOS API.
DBaaS services offered by IONOS Cloud:
Our platform is responsible for all back-end operations required to maintain your database in optimal operational health. The following services are offered:
Database management via the DCD or the DBaaS API.
Configuring default values, for example for data replication and security-related settings.
Automated backups for 7 days.
Regular patches and upgrades during the maintenance.
Disaster recovery via automated backup.
Service monitoring: both for the database and the underlying infrastructure.
Customer database administration duties:
Tasks related to the optimal health of the database remain the responsibility of the user. These include:
choosing adequate sizing,
data organization,
creation of indexes,
updating statistics, and
consultation of access plans to optimize queries.
Cluster: The whole MongoDB cluster is currently equal to the replica set.
Instance: A single server or replica set member inside a MongoDB cluster.
Maintenance window is a weekly four-hour window. All changes that may cause service interruption (like upgrades) will be executed within the maintenance windows. During maintenance window, an uncontrolled disconnections and inability to connect to cluster can happen. Such disconnections are destructive for any ongoing transactions and also clients should reconnect.
Maintenance window consists of two parts. The first part specifies the day of the week, while the second part specifies the expected time. Here is an example of a maintenance window configuration:
For more information, see Create a Cluster.
To guarantee partition tolerance, only odd numbers of cluster members are allowed. For the playground edition you can only have 1 replica. All other editions allow the use of 3 replicas. Soon we will allow more than 3 replicas per cluster.
The secondary instances are automatically highly available and replicate your data between instances. One instance is the primary, which accepts write transactions, and the others are secondary, which can optionally be used for read operations.
The instances in an IONOS MongoDB cluster are members of the same replica set, so all secondary instances replicate the data from the primary instance.
By default the write concern before acknowledging a write operations is set to "majority"
with j: true
. The term "majority"
means the write operation must be propagated to the majority of instances. In a three-instance cluster, for example, at least two instances must have the operation before the primary acknowledges it. The j
option also requires that the change has already been persisted to the on-disk journal of these instances.
If data is not replicated to the majority, it may be lost in the event of a primary instance failure and subsequent rollback.
You can change the write concern for single operations, for example due to performance reasons. For more information, see Write Acknowledgement.
You can determine which instance to use for read operations by setting the read preference on the client side, if your client supports it. For more information, see Read Preference.
If you read from the primary instance, you always get the most up-to-date data. You can spread the load by reading from secondary sources, but you might get stale data. However, you can get consistency guarantees using a Read Concern.
From the DCD, you can create and manage MongoDB Clusters. In the DCD, go to Menu > Databases > Postgres & MongoDB. You can view the resource allocation details for your user account that shows details of CPU Cores, RAM (in GB), and Storage data. In the MongoDB, you can create database clusters in the following editions: Playground, Business, and Enterprise. Each of these editions offer varied resource allocation templates and advanced features that you could choose from that suits your enterprise needs. For information on creating a MongoDB cluster via the DCD, see Set up a MongoDB Cluster.
Note: The Database Manager is available for contract administrators, owners, and users with Access and manage DBaaS privileges only. You can set the privilege via the DCD group privileges. For more information, see Assigning Privileges to Groups.
MongoDB Backups: A cluster can have multiple snapshots. A snapshot is a copy of the data in the cluster at a certain time and is added during the following cases:
When a cluster is created, known as initial sync which usually happens in less than 24 hours.
After a restore.
Every 24 hours, a base snapshot is taken, and every Sunday, a full snapshot is taken.
Snapshots are retained for the last seven days; hence, recovery is possible for up to a week from the current date. You can restore from any snapshot as long as it was created with the same or older MongoDB patch version.
Snapshots are stored in an IONOS S3 Object Storage bucket in the same region as your database. Databases in regions where IONOS S3 Object Storage is not available is backed up to eu-central-2
.
Warning: If you destroy a MongoDB cluster, all of its snapshots are also deleted.
MongoDB Enterprise edition supports Offsite Backups, this allows backup data being stored in a location other than the deployed database cluster.
Available locations are de
, eu-south-2
, eu-central-2
.
Info: The location can only be set during cluster creation. Changes to the backup location of a provisioned cluster will result in unexpected behaviour.
Recovery is achieved via the restore jobs. A restore job is responsible to create and catalog a cluster restoration process. A valid snapshot reference is required for a restore job to recover the database. The API exposes available snapshots of a cluster.
There must be no other active restore job for the cluster to create a new one.
Warning: When restoring a database, it is advised to avoid connections to it until its restore job is complete and the cluster reaches AVAILABLE
state.
This feature is available only for enterprise clusters. The restoration of cluster here includes points in time and operations log (oplog) timestamps. A custom snapshot can be created for the exact oplog timestamp that you choose to restore the database cluster is possible with point in time recovery.
For more information on restoring database from backup by using the Cloud API, see Restore a Database.
Note: Currently, DBaaS - MongoDB does not support scaling existing clusters.
The WiredTiger cache uses only a part of the RAM; the remainder is available for other system services and MongoDB calculations. The size of the RAM used for caching is calculated as 50% of (RAM size - 1 GB)
with a minimum of 256 MB. For example, a 1 GB RAM instance uses 256 MB, a 2 GB RAM instance uses 512 MB, a 4 GB instance uses 1.5 GB, and so on.
You get the best performance if your working set fits into the cache, but it is not required. The working set is the size of all indexes plus the size of all frequently accessed documents.
To view the size of all databases' indexes and documents, you can use a similar script as described in the MongoDB Atlas documentation. You must estimate what percentage of all documents are accessed at the same time based on your knowledge of the workload.
Additionally, each connection can use up to 1 MB of RAM that is not used by WiredTiger.
The disk contains:
OpLogs for the last 24 hours. The size of these depends on your workload. There is no upper limit, so they can grow quite large. But they are removed after 24 hours on their own.
The data itself. Operating systems and applications are kept separately outside the configured storage and are managed by IONOS.
Connection Limits: As each connection requires a separate thread, the number of connections is limited to 51200 connections.
CPU: The total upper limit for CPU cores depends on your quota. A single instance cannot exceed 31 cores.
RAM: The total upper limit for RAM depends on your quota. A single instance cannot exceed 230 GB.
Storage: The upper limit for storage size is 4 TB.
Backups: Storing cluster backups is limited to the last 7 days. Deleting a cluster also immediately removes all backups of it.
IP Ranges: The following IP ranges cannot be used with our MongoDB services:
172.16.0.0/12
192.168.230.0/24
You can add a MongoDB cluster on any of the following editions: Playground, Business, or Enterprise.
Prerequisites: Before setting up a database, make sure you are working within a provisioned VDC that contains at least one virtual machine (VM) from which to access the database. The VM you create is counted against the quota allocated in your contract. For more information on databases quota, see Resource Allocation.
Note: Database Manager is available for contract administrators, owners, and users with Access and manage DBaaS privileges only. You can set the privilege via the DCD group privileges.

In IONOS Managed Kubernetes, a Public Node Pool provides a foundation for hosting applications and services that require external accessibility over the internet. These node pools consist of worker nodes that are exposed to the public network, enabling them to interact with external clients and services.
The key features related to Public Node Pools include:
External Accessibility: Public Node Pools are designed to host workloads that need to be accessed from outside the Kubernetes cluster. This can include web applications, APIs, and other services that require internet connectivity.
Load Balancing: Load balancers are used with IONOS Public Node Pools to distribute incoming traffic across multiple nodes. This helps to achieve high availability, scalability, and efficient resource utilization.
Security: The Implementation of proper network policies, firewall rules, and user groups helps IONOS Public Node Pools mitigate potential risks and help in the protection of sensitive data.
Scaling: The ability to dynamically scale the number of nodes in a Public Node Pool is crucial for handling varying levels of incoming traffic. This scalability ensures optimal performance during peak usage periods.
Public Cloud Integration: Public Node Pools seamlessly integrate with IONOS Cloud services.
Monitoring and Logging: Robust monitoring and logging solutions are essential for tracking the performance and health of applications hosted in Public Node Pools. This includes metrics related to traffic, resource utilization, and potential security incidents.
Software development is constantly evolving, and security is a top priority. The Vulnerability Scanning feature is specifically designed to enhance the security of your containerized applications by proactively identifying potential vulnerabilities present in your artifacts. Scans take place every time an artifact is pushed to the registry and when new vulnerability definitions are published. This allows for quick detection of any security weaknesses in container dependencies and libraries, allowing you to react immediately to prevent exploitation.
Adopting the scanning feature is not just about maintaining security; it is also essential for complying with industry regulations, managing risks effectively, and sustaining the trust of your users. You can integrate the feature into your CI/CD pipeline, providing continuous security assessments to keep your containers safe in a fast-paced development environment.
We prioritize detected vulnerabilities based on severity, enabling you to focus on the most critical issues. Our recommendations for patch management, minimizing the attack surface, and using trusted base artifacts form part of a comprehensive security posture. By adopting the Vulnerability Scanning feature, you are taking a proactive approach to enable your team to safeguard your applications against emerging threats, ensuring the integrity of your software delivery.
Note: While we strive to provide accurate and up-to-date vulnerability information, it's important to note that the scanning results are contingent on the contents of third-party, market-leading vulnerability database(s). IONOS is not responsible for any missing definitions or inaccuracies in the database.
1. To add Vulnerability Scanning to a Container Registry, go to Menu > Containers > Container Registry.
2. In the Container Registry Manager, select the Container Registry you want to enable Vulnerability Scanning for.
3. Navigate to the Properties section and click on Enable in the Vulnerability Scanning area.
4. Confirm the action to enable Vulnerability Scanning.
You can create Kubernetes clusters for Public Node Pools using the or directly using the .

The Cloud API lets you manage Cubes resources programmatically using conventional HTTP requests. All the functionality available in the IONOS Cloud Data Center Designer is also available through the API.
You can use the API to create, destroy, and retrieve information about your Cubes. You can also use the API to suspend or resume your Cubes.
However, not all actions are shared between Dedicated Core Servers and Cubes. Since Cubes come with direct-attached storage, a composite call is required for setup.
Furthermore, when provisioning Cubes, Templates must be used. Templates will not be compatible with Servers that still support full flex configuration.
GET
https://api.ionos.com/docs/cloud/v6/#tag/Templates/cloudapi/v6/templates
This method retrieves a list of configuration templates that are currently available. Instances have a fixed configuration of vCPU, RAM and direct-attached storage size.
GET
https://api.ionos.com/docs/cloud/v6/#tag/Templates/cloudapi/v6/templates?depth=1
Retrieves Template information. Refine your request by adding the optional query parameter
depth
. The response will show a template's ID, number of cores, ram and storage size.
A composite call doesn't only configure a single instance but also defines additional devices. This is required because a Cube must include a direct-attached storage device. An instance cannot be provisioned and then mounted with a direct-attached storage volume. Composite calls are used to execute a series of REST API requests into a single API call. You can use the output of one request as the input for a subsequent request.
The payload of a composite call to configure a Cubes instance is different from that of a POST
request to create an enterprise server. In a single request you can create a new instance, as well as its direct-attached storage device and image (public image, private image, or snapshot). When the request is processed, a Cubes instance is created and the direct-attached storage is mounted automatically.
POST
https://api.ionos.com/cloudapi/v6/datacenter/{datacenterId}/servers
