ElastiCache

• ElastiCache provides a high-performance, scalable, and cost-effective caching solution.

• At the same time, it helps remove the complexity associated with deploying and managing a distributed cache environment.

• Build data-intensive apps or boost the performance of your existing databases by retrieving data from high throughput and low latency in-memory data stores.

• Amazon ElastiCache is a popular choice for real-time use cases like Caching, Session Stores, Gaming, Geospatial Services, Real-Time Analytics, and Queuing.

• Does not support IAM authentication.

• Choose Memcached (just a pure cache, no backups and restores, no data persistence)

• Choose Redis (backups, restores, Multi-AZ, data persistence, failovers, read replicas)
