What is Amazon ElastiCache?

Amazon ElastiCache is a fully managed in-memory caching service that supports Redis and Memcached engines. It improves application performance by retrieving data from fast, managed, in-memory caches instead of relying entirely on slower disk-based databases. ElastiCache enables sub-millisecond response times for read-heavy application workloads and compute-intensive workloads. It provides automatic failover, backup and restore, and cross-region replication for Redis. ElastiCache handles time-consuming management tasks like hardware provisioning, software patching, setup, configuration, monitoring, and failure recovery, allowing you to focus on high-value application development.
