Amazon ElastiCache is an Amazon Web Services (AWS) service that provides a high-performance, scalable, and cost-effective caching solution for distributing an in-memory data store or cache environment in the cloud. It retrieves data from high-throughput and low-latency, in-memory data stores. This functionality makes it a popular choice for real-time use cases such as caching, session stores, gaming, geo-spatial services, real-time analytics, and queuing. ElastiCache offers Redis and Memcached data stores, both of which provide sub-millisecond response times.
