Description

ElastiCache makes it easy to set up, manage, and scale distributed in-memory cache environments in the Cloud. It provides a high performance, resizable, and cost-effective in-memory cache. It was detected that the Elasticache cluster {AwsElasticacheRedisCluster} has Multi-AZ disabled. Enabling ElastiCache Multi-AZ on Redis cluster improves fault tolerance. The role of primary node will automatically fail over to one of the read replicas.

  Recommended Mitigation

  It is recommended to enable Multi-AZ. It can be done when creating a new Redis cluster or by modifying an existing Redis cluster with replication. For more information: https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/AutoFailover.html
