Overview

Represents an individual cache node within a cluster. Each cache node runs its own instance of the cluster's protocol-compliant caching software - either Memcached or Redis.

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:

      M6g node types (available only for Redis engine version 5.0.6 onward and for Memcached engine version 1.5.16 onward).

      cache.m6g.large, cache.m6g.xlarge, cache.m6g.2xlarge, cache.m6g.4xlarge, cache.m6g.8xlarge, cache.m6g.12xlarge, cache.m6g.16xlarge

      For region availability, see Supported Node Types

      M5 node types: cache.m5.large, cache.m5.xlarge, cache.m5.2xlarge, cache.m5.4xlarge, cache.m5.12xlarge, cache.m5.24xlarge

      M4 node types: cache.m4.large, cache.m4.xlarge, cache.m4.2xlarge, cache.m4.4xlarge, cache.m4.10xlarge

      T3 node types: cache.t3.micro, cache.t3.small, cache.t3.medium

      T2 node types: cache.t2.micro, cache.t2.small, cache.t2.medium

    • Previous generation: (not recommended)

      T1 node types: cache.t1.micro

      M1 node types: cache.m1.small, cache.m1.medium, cache.m1.large, cache.m1.xlarge

      M3 node types: cache.m3.medium, cache.m3.large, cache.m3.xlarge, cache.m3.2xlarge

  • Compute optimized:

    • Previous generation: (not recommended)

      C1 node types: cache.c1.xlarge

  • Memory optimized:

    • Current generation:

      R6g node types (available only for Redis engine version 5.0.6 onward and for Memcached engine version 1.5.16 onward).

      cache.r6g.large, cache.r6g.xlarge, cache.r6g.2xlarge, cache.r6g.4xlarge, cache.r6g.8xlarge, cache.r6g.12xlarge, cache.r6g.16xlarge

      For region availability, see Supported Node Types

      R5 node types: cache.r5.large, cache.r5.xlarge, cache.r5.2xlarge, cache.r5.4xlarge, cache.r5.12xlarge, cache.r5.24xlarge

      R4 node types: cache.r4.large, cache.r4.xlarge, cache.r4.2xlarge, cache.r4.4xlarge, cache.r4.8xlarge, cache.r4.16xlarge

    • Previous generation: (not recommended)

      M2 node types: cache.m2.xlarge, cache.m2.2xlarge, cache.m2.4xlarge

      R3 node types: cache.r3.large, cache.r3.xlarge, cache.r3.2xlarge, cache.r3.4xlarge, cache.r3.8xlarge

Additional node type info

  • All current generation instance types are created in Amazon VPC by default.

  • Redis append-only files (AOF) are not supported for T1 or T2 instances.

  • Redis Multi-AZ with automatic failover is not supported on T1 instances.

  • Redis configuration variables appendonly and appendfsync are not supported on Redis version 2.8.22 and later.
