ApsaraDB for MongoDB:Create a standalone instance

Last Updated:Mar 18, 2024

ApsaraDB for MongoDB provides cost-effective standalone instances to support business scenarios that involve non-core data storage, such as development, testing, learning, and training. This topic describes how to create a standalone instance.

Prerequisites

An Alibaba Cloud account is created. For more information, see Sign up with Alibaba Cloud.

Usage notes

  • Standalone instances take a long time to recover from failures and cannot be covered by a Service Level Agreement (SLA).

  • If your application is deployed on an Elastic Compute Service (ECS) instance, make sure that your ApsaraDB for MongoDB instance and ECS instance meet the following requirements to ensure network connectivity: For more information about how to view the information of ECS instances, see View instance information.

    • Your ApsaraDB for MongoDB instance and ECS instance are deployed in the same region.

    • Your ApsaraDB for MongoDB instance and ECS instance use the same network type.

      Note
      • The same zone is recommended because the same zone reduces network latency.

      • VPC is recommended because VPC provides higher security.

      • If the network type is VPC, you must ensure that they use the same VPC ID.

      • If you want to use VPC, but the network type of the ECS instance is classic network, you can change the network type of the ECS instance to VPC. For more information, see Migrate ECS instances from the classic network to a VPC.

Limits

  • Standalone instances can be deployed only in specific regions and zones. For more information about the supported regions and zones, see Available regions and zones.

  • Standalone instances can run only MongoDB 3.4 or 4.0.

    Important Instances that run MongoDB 3.4 have been unavailable as of January 1, 2023. For more information, see [Notice] End of sale for MongoDB 3.4 instances as of January 1, 2023.
  • Standalone instances do not support incremental data migration, incremental data synchronization, or point-in-time data restoration by creating an instance.

Billing rules

An Alibaba Cloud account is created. For more information, see Sign up with Alibaba Cloud.

  • Subscription: If you purchase a subscription instance, you must pay an upfront fee for the instance.

  • Pay-as-you-go: A pay-as-you-go instance is charged per hour based on the configuration of the instance. Fees are automatically deducted from your Alibaba Cloud account.

Note

For more information, see Billable items.

Procedure

After you perform the following steps, ApsaraDB for MongoDB automatically creates one or more standalone instances. No manual operations are required.

  1. Log on to the ApsaraDB for MongoDB console .

  2. In the left-side navigation pane, click Replica Set Instances.

  3. On the Replica Set Instances page, click Create Instance.

  4. On the page that appears, set Product Type to Replica Set (Subscription) or Replica Set (Pay-as-you-go).

  5. Configure the parameters described in the following table.

    Parameter

    Description

    Region

    The region in which you want to deploy the standalone instance. For more information about the regions in which you can create standalone instances, see the "Limits" section in the Create a standalone instance topic.

    Note
    • After you create the standalone instance, you cannot change the region of the instance. Proceed with caution.

    • If your application is deployed on an Elastic Compute Service (ECS) instance, we recommend that you deploy the standalone instance in the region where the ECS instance resides. If the standalone instance and the ECS instance reside in different regions, your application cannot communicate with the standalone instance over an internal network.

    Zone

    The zone in which you want to deploy the standalone instance. For more information about the zones in which you can create standalone instances, see the "Limits" section in the Create a standalone instance topic.

    Note

    If your application is deployed on an ECS instance, we recommend that you deploy the standalone instance in the zone where the ECS instance resides to reduce network latency.

    Engine Version

    The MongoDB version of the standalone instance.

    Active-standby Nodes

    The number of active-standby nodes in the standalone instance. Select Standalone.

    Read-only Nodes

    Storage Type

    Set the value to ESSD PL1.

    Network Type

    The type of network in which you want to deploy the standalone instance. Set the value to VPC.

    Note
    • A virtual private cloud (VPC) is an isolated network that provides higher security and higher performance than the classic network.

    • If your application is deployed on an ECS instance, you must make sure that the ECS instance is deployed in a VPC. This ensures network connectivity between your application and the standalone instance.

    VPC

    The ID of the VPC in which you want to deploy the standalone instance. If no VPCs are available, you can create a VPC in the VPC console. For more information, see Create and manage a VPC.

    vSwitch

    The ID of the vSwitch to which the standalone instance is connected. If no vSwitches are available, you can create a vSwitch in the VPC console. For more information, see Create and manage a vSwitch.

    Category

    The category of the standalone instance. You can set this parameter only to General-purpose for the standalone instance.
