// Amazon ElastiCache is a web service that makes it easier to set up, operate,
// and scale a distributed cache in the cloud.
//
// With ElastiCache, customers gain all of the benefits of a high-performance,
// in-memory cache with far less of the administrative burden of launching and
// managing a distributed cache. The service makes setup, scaling, and cluster
// failure handling much simpler than in a self-managed cache deployment.
//
// In addition, through integration with Amazon CloudWatch, customers get enhanced
// visibility into the key performance statistics associated with their cache
// and can receive alarms if a part of their cache runs hot.
//The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
