ECS Specifications Used by MRS
==============================
MRS uses ECSs of the following types in different application scenarios.
- General computing (S1)
- General computing (S3)
- General computing (C2)
- General computing-plus (C3)
- General computing-plus (C4)
- General computing-plus (C6)
- Disk-intensive (D1)
- Disk-intensive (D2)
- High-performance computing (H1)
- Memory-optimized (M3)
- Memory-optimized (M4)
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.
