What is ElastiCache?


ElastiCache is a managed in-memory caching service (Cache is a temporary storage area) ElastiCache can launch either Memcached or Redis Memcached is a simple key / value store preferred for caching HTML fragments and is arguably faster than Redis Redis has richer data types and operations. Great for leaderboard, geospatial data or keeping of unread notifications. Most frequently identical queries are stored in the cache Resources only within the same VPC may connect to ElastiCache to ensure low latencies.
