ApsaraDB for MongoDB:Standalone instance types

Last Updated:Jul 23, 2024

This topic describes the available instance types of ApsaraDB for MongoDB standalone instances.

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 capacity may be less than the memory capacity that is supported by the instance type.
