Elastic Compute Service:Retired ECS instance types

Last Updated:Oct 31, 2024

This topic describes all retired instance types on the China site (aliyun.com). However, the sn1, sn2, n1, n2, and e3 instance types are still available for purchase on the International site (alibabacloud.com).

Instance type changes

If you are using a retired instance type, we recommend that you change the instance type to another instance type that is available for purchase. For information about the supported changes between instance types, see Instance families that support instance type changes.

Series I instance families

Series I instance families include t1, s1, s2, s3, m1, m2, c1, and c2. All these instance families are legacy shared instance families. They are categorized based on the number of cores such as 1, 2, 4, 8, or 16 cores.

Features:

  • Use Intel Xeon E5-2420 processors with clock speeds of no less than 1.9 GHz.

  • Use the latest DDR3 memory.

  • Are instance families in which instances can be I/O optimized or non-I/O optimized.

I/O optimized instance types support standard SSDs and ultra disks. The following table describes the instance types and their specifications.
