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: M7g node types: `cache.m7g.large`, `cache.m7g.xlarge`, `cache.m7g.2xlarge`, `cache.m7g.4xlarge`, `cache.m7g.8xlarge`, `cache.m7g.12xlarge`, `cache.m7g.16xlarge`For region availability, see [Supported Node Types](https://docs.aws.amazon.com/AmazonElastiCache/latest/dg/CacheNodes.SupportedTypes.html#CacheNodes.SupportedTypesByRegion)M6g node types (available only for Redis OSS 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` 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` T4g node types (available only for Redis OSS engine version 5.0.6 onward and Memcached engine version 1.5.16 onward): `cache.t4g.micro`, `cache.t4g.small`, `cache.t4g.medium` 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.
