/**
* Interface for accessing Amazon ElastiCache.
*
* Amazon ElastiCache
*
* 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.
