Set Up a MongoDB Cluster

You can add a MongoDB cluster on any of the following editions: Playground, Business, or Enterprise.

Create a Cluster

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.

To create a MongoDB cluster, follow these steps:

1. In the DCD, go to Menu > Databases > MongoDB.

Info: The Resource allocation section displays the resources allotted to your contract and the number of used and unused resources if you have already created MongoDB clusters.

2. In the MongoDB cluster overview window, click Create cluster to create a new MongoDB cluster.

3. Specify the following in the Properties section:

• Provide an appropriate Cluster Name.

• From the drop-down list, choose a Location where your data for the database cluster can be stored. You can select an available data center within the cluster's data directory to create your cluster.

• Select the appropriate MongoDB Version. The IONOS Database Manager supports MongoDB versions 6.0 and 7.0.

4. Choose an Edition.

Playground

In the Playground edition, the following standard resources are available:

• RAM Size (GB): 2.

• vCPU: 1.

• Storage Size: 50 GB.

Note: You can create one playground instance for free and test MongoDB. For every additional instance that you create apart from the first instance, the charges are applicable accordingly.

Enterprise

5. Configure your cluster in the Cluster configuration section.

Playground

• Database type: It is set to Replica Set, by default. This database type maintains replicas of data sets and offers redundancy and high data availability.

Note: The Sharded Cluster database type is not available for selection in the Playground edition.

• Instances: By default, one instance is offered for free in this edition to host a logical database manager environment to catalog your databases.

Enterprise

6. Upon selecting Enterprise edition, you can choose from the following in the Resources section.

Info: The Resources selection is applicable only for Enterprise edition. For Playground, and Business edition, continue with step 7.

• Number of CPUs (per instance): You can choose between 1 and 31 CPU cores using the slider or choose from the available shortcut values.

• RAM Size (per instance): Values of up to 230 GB RAM sizes are possible. Select the RAM size using the slider or choose from the available shortcut values.

• Storage Type: The SSD Premium, SSD Standard, or HDD storage options are available.

• Storage Size: Set the storage size value to at least 100 GB in case of SSD Standard and Premium storage types for optimal performance of the database cluster. You can configure the storage size to a maximum of 4 TB.

Selecting resources

7. In the Network configuration section, set up the following:

Prerequisite: Make sure you have a data center configured with a dedicated private LAN available. To do so, Create a Data Center, Configure the data center and Configure a private LAN.

1. Datacenter: Select a data center from the drop-down list.

2. Datacenter LAN: Select a LAN for the chosen data center. The drop-down list shows all the available private LANs.

3. IP/Subnet: Enter the private IP or subnet address in the correct format by using the available Private IPs. For Business and Enterprise editions, specify one private IP/Subnet address detail for every instance based on the chosen number of Instances.

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 that NIC in that LAN or retrieve the subnet assigned to the LAN using the ipv4CidrBlock property of the API call Retrieve LANs/mark>. 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, then you need to discover the IP address on your own.

8. In the Maintenance period (optional) section, set the following:

• Day: From the drop-down list, choose the preferred day on which the maintenance of the cluster must take place.

• Start Time (UTC): Set the time (in UTC) for the maintenance of the MongoDB cluster. Use the pre-defined format (hh:mm:ss) or you can use the clock. The maintenance occurs in a 4-hour-long window.

9. Click Save to provision the creation of the MongoDB cluster.

Note: The Estimated price will be displayed based on the input. The estimated cost is exclusive, where certain variables like traffic and backup are not considered.

Result: The MongoDB cluster with the chosen edition is created.
