Amazon ElastiCache
Overview
Amazon ElastiCache is a fully managed, Valkey-, Memcached- and Redis OSS-compatible service that delivers real-time, cost-optimized performance for modern applications with 99.99% availability. ElastiCache speeds up database and application performance, scaling to millions of operations per second with microsecond response time. ElastiCache also offers enhanced security and reliability when compared to open source alternatives. For modern applications, ElastiCache Global Datastore offers localized reads through fully-managed cross-Region replication. ElastiCache also unlocks cost savings for read-heavy and memory-intensive workloads with additional cost optimization features like data tiering. ElastiCache provides leading security (Amazon VPC, Amazon IAM) and compliance standards (HIPAA eligible, FedRAMP authorized, and PCI DSS).
