ECS Flavor Naming Rules

AB.C.D

For example, s2.medium.4,

Figure 1 ECS flavor naming rules

The format is defined as follows:

  • AB indicates the ECS type and type ID.
    • A specifies the ECS type. For example, s indicates a general-purpose ECS, c a computing ECS, and m a memory-optimized ECS.

      Kunpeng flavor names are started with letter k. For example, kc indicates Kunpeng general computing-plus.

    • B specifies the type ID. For example, the 1 in s1 indicates a general first-generation ECS, and the 2 in s2 indicates a general second-generation ECS. Generally, a larger number indicates a newer-generation ECS, which is more cost-effective. For example, compared with s1 and s2, s6 is a next-generation general computing ECS.
  • C specifies the flavor size (the number of vCPUs), such as small, medium, large, xlarge, 2xlarge, 4xlarge, and 8xlarge.
  • 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.

Network Bandwidth

The intranet bandwidth and PPS of an ECS are determined by ECS flavor.
  • Assured intranet bandwidth: indicates the assured ECS bandwidth.
  • Maximum intranet bandwidth: indicates the maximum ECS bandwidth.
  • Maximum intranet PPS: indicates the maximum ECS capability in transmitting and receiving packets.
