Amazon ElastiCache is a fully managed in-memory data store and cache service that supports open-source engines like Redis and Memcached, making it ideal for low-latency, high-throughput Amazon DynamoDB is a NoSQL database, not in-memory. Amazon EBS provides block storage for EC2 instances, not an in-memory store. Amazon Redshift is a data warehouse optimized for analytics, not for in-memory caching.
