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

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
andappendfsync
are not supported on Redis version 2.8.22 and later.
