This topic describes available instance types of standalone 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.
