Cache engines supported:

• Memcached – widely adopted memory object caching system.
• Redis – popular open-source in-memory key-value store that supports data structures such as sorted sets and lists.
  • ElastiCache supports Redis master / slave replication which can be used to achieve cross AZ redundancy.

Features:

• Ease of management via the AWS Management Console.
• Compatibility with the specific engine protocol.
• Detailed monitoring statistics for the engine nodes at no extra cost via Amazon CloudWatch
