Amazon ElastiCache
Serverless, fully managed caching service delivering microsecond latency performance with full Valkey, Memcached, and Redis OSS compatibility
What is ElastiCache
ElastiCache Serverless offers zero infrastructure management, zero downtime maintenance, and instant scaling, handling billions of requests per second across hundreds of thousands of customers. 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 for persistent data protection against failures. For multi-Region applications, ElastiCache Global Datastore offers local reads through fully managed, cross-Region replication. As ElastiCache is fully open source compatible, you can migrate to a managed solution with minimal to no application code changes.
Benefits of ElastiCache
Use cases
Scale to hundreds of millions of operations per second with microsecond latency and high throughput while reducing costs by caching frequently used data in memory.
Achieve lowest latency vector search with highest throughput and best price-performance at 95% recall rate among popular vector databases on AWS by using semantic caching for both agentic AI (such as conversational memory) and generative AI (such as Retrieval Augmented Generation) use cases.
Protect your data against the 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.
Personalize gaming, e-commerce, social media, and online applications with microsecond latency by caching ephemeral session data.
Simplify application development with ElastiCache built-in data structures such as hashes, lists, sorted sets, and more.
