/**
 * Amazon ElastiCache is a web service that makes it easier to set up, operate, and scale a
 * distributed cache in the cloud.
 *  
 * With Amazon 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 set-up, 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.
