ApsaraDB for MongoDB:Replica set instance types

Last Updated:Mar 18, 2024

This topic describes the available instance types of replica set instances in ApsaraDB for MongoDB.

Note

The supported memory capacity includes the memory that is occupied by the management services in ApsaraDB for MongoDB, the database service, and the underlying operating system (such as the BIOS, the kernel of the operating system, and the hypervisor). Therefore, the available memory may be less than the memory capacity that is supported by the instance type.

Instances that use cloud disks

The following database engine versions are supported:

  • MongoDB 7.0

  • MongoDB 6.0

  • MongoDB 5.0

  • MongoDB 4.4
