Amazon ElastiCache automatically detects and replaces failed nodes, reducing the overhead associated with self-managed infrastructures and provides a resilient system that mitigates the risk of overloaded databases, which slow website and application load times. Through integration with Amazon CloudWatch, Amazon ElastiCache provides enhanced visibility into key performance metrics associated with your Redis or Memcached nodes. Using Amazon ElastiCache, you can add an in-memory layer to your infrastructure in a matter of minutes by using the AWS Management Console.
