Caching in a cloud environment is useful for applications to reduce the latency and to save database round trips. Reducing database round trips can significantly reduce the requirements for the database instance. The Spring Framework provides, since version 3.1, a unified Cache abstraction to allow declarative caching in applications analogous to the declarative transactions.
Spring Cloud AWS integrates the Amazon ElastiCache service into the Spring unified caching abstraction providing a cache manager based on the memcached and Redis protocols. The caching support for Spring Cloud AWS provides its own memcached implementation for ElastiCache and uses Spring Data Redis for Redis caches.
