Description

ElastiCache is a fully managed, in-memory data store service that provides high-performance and scalable caching solutions in the cloud. An ElastiCache cluster is a collection of one or more cache nodes that work together to provide high performance and scalable caching of data in-memory. In order to keep the cluster up-to-date with the latest security updates, it is recommended to set a preferred maintenance window, during which those updates are applied automatically.
