AWS Trusted Advisor adds new fault tolerance checks

AWS Trusted Advisor has launched five fault tolerance checks across Amazon MQ, EC2 Nat Gateway and Amazon OpenSearch. AWS Trusted Advisor evaluates your AWS account with automated checks and provides cloud optimization recommendations to reduce costs, improve performance, increase security and fault tolerance, and monitor service quotas. The two [Amazon MQ](https://aws.amazon.com/amazon-mq/) fault tolerance checks identify if the ActiveMQ and RabbitMQ brokers on Amazon MQ are configured for high availability. The [EC2 NAT Gateway](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-nat-gateway.html) fault tolerance check evaluates if your NAT Gateways are configured with Availability Zone (AZ) independence. The Single AZ Application Check evaluates if your application is deployed only in one AZ. The [Amazon OpenSearch](https://aws.amazon.com/opensearch-service/) check identifies if OpenSearch domains have at least three data nodes for high availability. The Amazon MQ checks are available in all commercial and the AWS GovCloud (US) Regions, while the other checks are only available in commercial regions. AWS Premium Support customers can access the fault tolerance checks from the [AWS Trusted Advisor Console](http://console.aws.amazon.com/trustedadvisor/), or via the [AWS Support API](https://docs.aws.amazon.com/awssupport/latest/APIReference/Welcome.html).
