Amazon ElastiCache
Amazon ElastiCache allows you to seamlessly set up, run, and scale popular open-source compatible in-memory data stores in the cloud. Build data-intensive apps or boost the performance of your existing databases by retrieving data from high throughput and low latency in-memory data stores. Amazon ElastiCache is a popular choice for real-time use cases like Caching, Session Stores, Gaming, Geospatial Services, Real-Time Analytics, and Queuing.
Amazon ElastiCache offers fully managed Redis, voted the most loved database by developers in the Stack Overflow 2020 Developer Survey, and Memcached for your most demanding applications that require sub-millisecond response times.
Benefits
Extreme performance
Amazon ElastiCache works as an in-memory data store and cache to support the most demanding applications requiring sub-millisecond response times. By utilizing an end-to-end optimized stack running on customer dedicated nodes, Amazon ElastiCache provides secure, blazing fast performance.

Customers
Learn how The Pokémon Company moved user caching to Amazon ElastiCache, taking advantage of both Redis and Memcached. Redis queues tasks for new users, so they can be prompted to complete post-authentication tasks such as accepting terms and conditions. Memcached helps keep tickets live so that existing users’ sessions are not interrupted when new users join.
