Amazon ElastiCache
What is ElastiCache?
Amazon ElastiCache is a serverless caching service delivering microsecond latency for agents, databases, and analytics with full Valkey compatibility. It offers zero infrastructure management, zero downtime maintenance, and instant scaling to over ten billion requests per second to match any application demand. ElastiCache powers agentic AI workloads with semantic and prompt caching, reducing LLM inference costs and latency by serving cached responses for repeated or semantically similar queries. For added resilience, you can enable durability to use ElastiCache as a persistent data store with automatic failover, backups, and snapshots protecting your data against failures. For multi-Region applications, ElastiCache Global Datastore offers local reads through fully managed, cross-Region replication. As ElastiCache is fully Valkey-compatible, you can migrate to a managed solution with minimal to no application code changes. ElastiCache also provides leading security (Amazon VPC, Amazon IAM) and compliance standards .
Benefits
Fast response times

Business continuity
Achieve a 99.99% SLA with multi AZ deployments and bolster disaster recovery with cross-region replication
Valkey-, Memcached- and Redis OSS compatible
Build applications quickly using popular open source Valkey, Memcached and Redis APIs.
Improve resilience
Strengthen your disaster recovery posture through durability to recover without data loss and multi-Region capabilities while maintaining local low-latency performance, and achieve up to 99.99% availability.
How It Works
Use Cases
Achieve cost savings, faster response times, and improved accuracy in generative AI applications by using semantic caching for both conversational memory and retrieval-augmented generation.
Protect your data against rare event of a failure while maintaining microsecond read latency for workloads such as knowledge bases for RAG, AI agent long-term memory, payment tokenization, and real-time inventory management.
Store frequently used data in memory for microsecond response times and high throughput to support hundreds of millions of operations per second.
Store ephemeral session data to quickly personalize gaming, e-commerce, social media, and online applications with microsecond response times.
Simplify application development with ElastiCache built-in data structures.
