This topic describes the available instance types of ApsaraDB for MongoDB replica set instances.
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.
Some instance types were upgraded on May 14, 2024. If the maximum number of connections to your instance is different from that described in this topic, you can restart the instance. For more information, see [Notice] Increase in the maximum connections to instances of specific specifications.
Instances that use cloud disks
The following database engine versions are supported:
MongoDB 8.0
MongoDB 7.0
MongoDB 6.0
MongoDB 5.0
MongoDB 4.4
Note
For more information about the maximum IOPS and throughput of different disk types, see ESSDs and ESSD AutoPL disks.
