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.

1. In the Data Center Designer, click the Databases menu.

2. In the Databases page, click + Add in the MongoDB Clusters section.

3. Provide an appropriate Display Name.

4. 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.

5. Choose the Edition type as Playground. In this edition, you can create one playground instance for free and test MongoDB.

Note: For every additional instance that you create apart from the first instance, the charges are applicable accordingly.

6. Select the Template to use the resources for creating your MongoDB cluster. In the Playground edition, the following standard resources are available:

RAM Size (GB): 2.
vCPU: 1.
Storage Size: 50 GB.

7. Select the Database Type as the Replica Set. 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.

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

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.

9. In the Cluster to Datacenter Connection section, set up the following:

Select a Data Center: Select a data center from the available list. Use the search option to enter a data center that you want to select.
LAN in the selected Datacenter: Select a LAN for the chosen data center.

10. In the Private IP/Subnet, perform the following actions:

Private IP/Subnet: Enter the private IP or subnet address in the correct format by 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 that NIC in that LAN. The DHCP in that LAN is always using a /24 subnet, so you have to reuse the first 3 IP blocks 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.

Click Add to save the private IP/Subnet address details.
Click Add Connection to connect the cluster to the data center.

11. Select the appropriate MongoDB Version. The IONOS Database Manager supports 5.0 and 6.0 MongoDB versions.

12. In the Maintenance Window, set the following:

Maintenance time: 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, adjust the time accordingly.
Maintenance day: From the dropdown menu, choose the preferred day on which the maintenance of the cluster must take place.

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

Result: The MongoDB cluster for the defined values is created in the Playground edition.

1. In the Data Center Designer, click the Databases menu.

2. In the Databases page, click + Add in the MongoDB Clusters section.

3. Provide an appropriate Display Name.

5. Choose the Edition type as Business.

6. Select the Template to use the resources needed for creating your MongoDB cluster. In the Business edition, the resources varying from MongoDB Business XS to MongoDB Business 4XL_S are made available. Each template differs based on the RAM Size (GB), vCPU, and Storage Size.

Note: Depending on the resource limit allocation as per your contract, some of the templates may not be available for selection.

7. Select the Database Type as the Replica Set. This database type maintains replicas of data sets and offers redundancy and high availability of data.

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

8. Choose the Instances to host a logical database manager environment to catalog your databases. By default, one instance and three instances are possible in the Business edition.

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.

9. In the Cluster to Datacenter Connection section, set up the following:

Select a Data Center: Select a data center from the available list. Use the search option to enter a data center that you want to select.
LAN in the selected Datacenter: Select a LAN for your data center.

10. In the Private IP/Subnet, perform the following actions:

Private IP/Subnet: Enter the private IP or subnet address in the correct format by using the available Private IPs. Depending on the number of instances selected in step 8, you need to enter one private IP/Subnet address detail for every instance.

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. The DHCP in that LAN is always using a /24 subnet, so you have to reuse the first 3 IP blocks 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.

Click Add to save the private IP/Subnet address details.
Click Add Connection to connect the cluster to the data center.

11. Select the appropriate MongoDB Version. The IONOS Database Manager supports 5.0 and 6.0 MongoDB versions.

12. In the Maintenance Window, set the following:

Maintenance time: 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, adjust the time accordingly.
Maintenance day: From the dropdown menu, choose the preferred day on which the maintenance of the cluster must take place.

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

Result: The MongoDB cluster for the defined values is created in the Business edition.

1. In the DCD, click the Databases menu.

2. In the Databases page, click + Add in the MongoDB Clusters section.

3. Provide an appropriate Display Name.

5. Choose the Edition type as Enterprise.

6. Choose the following resources for creating each node of your MongoDB cluster. The total billed resources will be these values multiplied by the number of instances and the number of shards (if applicable).

CPU Cores: You can choose between 1 and 31 CPU cores using the slider or choose from the available shortcut values.
RAM Size (GB): 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 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.

7. Select the Database Type from the following:

Replica Set: Maintains replicas of datasets; offers redundancy and high availability of data.
Sharded Cluster: Maintains collection of datasets that are distributed across many shards (servers) and hence offers horizontal scalability. Define the Amount of Shards between two to a maximum of thirty-two shards.

Note: For sharded clusters, an additional three config server instances are created with sizing of two cores, 4 GB of memory, and 40 GB of storage each. These instances are excluded from the billed resources.
