AWS Trusted Advisor fault tolerance checks for Amazon ECS are now generally available. AWS Trusted Advisor evaluates your AWS account with automated checks and provides cloud optimization recommendations to reduce costs, improve performance, increase security, increase fault tolerance, and monitor service quotas.

The first fault tolerance check, Amazon ECS service using a single Availability Zone (AZ) examines if your service configuration uses a single Availability Zone. By launching instances in multiple AZs in the same region, you can protect applications from a single point of failure. The second fault tolerance check, Amazon ECS Multi-AZ placement strategy evaluates if your service is configured to use the spread placement strategy to spread tasks across multiple AZs.

The Amazon ECS fault tolerance checks for Trusted Advisor are available in the following regions: US East (Ohio), US East (N. Virginia), US West (N. California), US West (Oregon), Asia Pacific (Mumbai), Asia Pacific (Osaka), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Canada (Central), Europe (Frankfurt), Europe (Ireland), Europe (London), Europe (Paris), Europe (Stockholm), South America (São Paulo), AWS GovCloud (US-East), and AWS GovCloud (US-West).
