ApsaraDB for MongoDB:Standalone instances

Last Updated:Aug 15, 2023

ApsaraDB for MongoDB standalone instances are highly cost-effective and suitable for scenarios that do not require the storage of crucial business data. For example, you can use standalone instances in scenarios such as development, testing, learning, and training.


Standalone instances take a long time to recover from failures and have no Service Level Agreement (SLA) guarantees.



  • A standalone instance provides only one node that is used to read and write data.
  • Standalone instances allow you to enjoy the O&M support and kernel optimization of ApsaraDB MongoDB at lower prices. You can select appropriate instance specifications for different business scenarios to reduce costs. For more information, see Instance types.


  • Q: Do standalone instances provide high availability?

    A: No, standalone instances do not provide high availability. A standalone instance has only one node, and a failure may cause a service interruption for around 30 minutes for the instance at worst. We recommend that you use replica set or sharded cluster instances in production environments.

  • Q: Do standalone instances support incremental data migration, incremental data synchronization, and point-in-time data restoration to a new instance?

    A: No, these features are not supported by standalone instances. By default, standalone instances do not support oplogs. As such, these features cannot be supported by standalone instances.
