Amazon Trusted Advisor fault tolerance checks for ElastiCache for Redis and MemoryDB for Redis are now generally available in the Amazon Web Services China (Beijing) Region, operated by Sinnet and the Amazon Web Services China (Ningxia) Region, operated by NWCD. With this launch, the Trusted Advisor fault tolerance checks for ElastiCache for Redis are now available in all Amazon Web Services regions. Amazon Trusted Advisor evaluates your Amazon Web Services account with automated best practice checks and provides cloud optimization recommendations to reduce costs, improve performance, increase security, and monitor service quotas.

The new fault tolerance checks for Amazon ElastiCache Multi-AZ Clusters and Amazon MemoryDB Multi-AZ Clusters alert customers when they're running in a Single-AZ configuration and provide recommendations to customers on how to enable Multi-AZ with automatic failover in their ElastiCache or MemoryDB clusters. By enabling Multi-AZ with automatic failover, customers benefit from minimal administrative intervention, improved fault tolerance, and enhanced availability of their Redis clusters. For more information, see Minimizing downtime in ElastiCache with Multi-AZ or Minimizing downtime in MemoryDB with Multi-AZ.  

Amazon Web Services Business Support and Amazon Web Services Enterprise Support customers can access the fault tolerance checks from the Amazon Trusted Advisor Console, or via the Amazon Web Services Support API.
