The AWS Trusted Advisor fault tolerance check for Amazon MemoryDB for Redis is now generally available in 4 new regions: Asia Pacific (Hong Kong), Europe (Milan), China (Beijing, operated by Sinnet), and China (Ningxia, operated by NWCD). With this launch, the AWS Trusted Advisor fault tolerance check for MemoryDB is now available in all regions where MemoryDB is generally available. AWS Trusted Advisor evaluates customers’ AWS accounts with automated best practice checks and provides cloud optimization recommendations to reduce costs, improve performance, increase security, and monitor service quotas. 

The fault tolerance check for Amazon MemoryDB 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 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 MemoryDB with Multi-AZ.

AWS Business Support, AWS Enterprise On-Ramp Support and AWS Enterprise Support customers can access the fault tolerance check from the AWS Trusted Advisor Console, or via the AWS Support API. For more information please visit the AWS Trusted Advisor webpage and the documentation site for a complete list of check references.
