ECS Flavor Naming Rules
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.
