Amazon ElastiCache is a web service that makes it easy to deploy, operate, and scale an in-memory cache in the cloud. Amazon ElastiCache improves the performance of web applications by allowing you to retrieve information from a fast, managed, in-memory caching system, instead of relying entirely on slower disk-based databases. The service simplifies and offloads the management, monitoring and operation of in-memory cache environments, enabling your engineering resources to focus on developing applications. Using Amazon ElastiCache, you can not only improve load and response times to user actions and queries, but also reduce the cost associated with scaling web applications.

Amazon ElastiCache automates common administrative tasks required to operate a distributed cache environment. Using Amazon ElastiCache, you can add a caching layer to your application architecture in a matter of minutes via a few clicks of the AWS Management Console. Once a cache cluster is provisioned, Amazon ElastiCache automatically detects and replaces failed cache nodes, providing a resilient system that mitigates the risk of overloaded databases, which slow website and application load times. Through integration with Amazon CloudWatch monitoring, Amazon ElastiCache provides enhanced visibility into key performance metrics associated with your cache nodes. Amazon ElastiCache is protocol-compliant with Memcached, a widely adopted memory object caching system, so code, applications, and popular tools that you use today with your existing Memcached environments will work seamlessly with the service. As with all Amazon Web Services, there are no up-front investments required, and you pay only for the resources you use.
