MRS uses ECSs of the following types in different application scenarios.

AB.C.D

Example: m3.8xlarge.8

In the preceding flavor:

A specifies the ECS type. For example, s indicates a general-purpose ECS, c a computing ECS, and m a memory-optimized ECS.
B specifies the type ID. For example, the 1 in s1 indicates a general-purpose first-generation ECS, and the 2 in s2 indicates a general-purpose second-generation ECS.
C specifies a flavor size and can be any of the following options: medium, large, and xlarge.
D specifies the ratio of memory to vCPUs expressed in a digit. For example, value 4 indicates that the ratio of memory to vCPUs is 4.
