Amazon Web Service- ElastiCache

 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.

For example, if you are running an online business, customers continuously asking for the information of a particular product. Instead of front-end going and always asking information for a product, you can cache the data using Elasticache.
