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 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.

allow network ingress.

API will apply any modified cache parameter groups to the
cache cluster. The reboot action takes place as soon as
possible, and results in a momentary outage to the cache
