 Amazon Web Service- Elasticache

It is an in-memory cache service with support for Memcached and Redis. Elasticache is a web service used to deploy, operate, and scale an in-memory cache in the cloud. It improves the performance of web applications by allowing you to retrieve information from fast, managed in-memory cache instead of relying entirely on slower disk-based databases.
