• ElastiCache is a managed in-memory caching service.
  • 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 track of unread notifications.
  • A cache is a temporary storage area.
  • Most frequently identical queries are stored in the cache.
  • Resources only within the same VPC may connect to ElastiCache to ensure low latencies.
