Defined in:
gems/aws-sdk-elasticache/lib/aws-sdk-elasticache/types.rb

Overview

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

Valid node types are as follows:

  • 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: cache.c1.xlarge

  • Memory optimized:

    • Current generation: cache.r3.large, cache.r3.xlarge, cache.r3.2xlarge, cache.r3.4xlarge, cache.r3.8xlarge

    • Previous generation: cache.m2.xlarge, cache.m2.2xlarge, cache.m2.4xlarge

Notes:

  • All T2 instances are created in an Amazon Virtual Private Cloud (Amazon VPC).

  • Redis backup/restore is not supported for Redis (cluster mode disabled) T1 and T2 instances. Backup/restore is supported on Redis (cluster mode enabled) T2 instances.

  • Redis Append-only files (AOF) functionality is not supported for T1 or T2 instances.

For a complete listing of node types and specifications, see Amazon ElastiCache Product Features and Details and either Cache Node Type-Specific Parameters for Memcached or Cache Node Type-Specific Parameters for Redis.
