Supported Node Types

The following node types are supported by ElastiCache. Generally speaking, the current generation types provide more memory and computational power at lower cost when compared to their equivalent previous generation counterparts.

  • General purpose:

    • Current generation:

      cache.t2.micro, cache.t2.small, cache.t2.medium, cache.m3.medium, cache.m3.large, cache.m3.xlarge, cache.m3.2xlarge, cache.m4.large, cache.m4.xlarge, cache.m4.2xlarge, cache.m4.4xlarge, cache.m4.10xlarge

    • Previous generation:

      cache.t1.micro, cache.m1.small, cache.m1.medium, cache.m1.large, cache.m1.xlarge

  • Compute optimized:

    • Previous generation: (not recommended)

      cache.c1.xlarge

  • Memory optimized:

    • Current generation:

      cache.r3.large, cache.r3.xlarge, cache.r3.2xlarge, cache.r3.4xlarge, cache.r3.8xlarge

    • Previous generation:
