The fault tolerance check for Amazon ElastiCache Multi-AZ Clusters alerts customers when they're running in a Single-AZ configuration and provides recommendations on how to enable Multi-AZ with automatic failover in their ElastiCache clusters. By enabling Multi-AZ with automatic failover, customers benefit from minimal administrative intervention, improved fault tolerance, and enhanced availability of their Redis clusters.
