AWS Trusted Advisor is a fully managed service that provides you guidance to follow AWS best practices. During establishing a new workflow, developing applications, or as part of ongoing improvement, take advantage of the recommendations provided by Trusted Advisor regularly to help keep your solutions provisioned optimally.
Trusted Advisor evaluates your account by using checks. These checks identify ways to optimize your AWS infrastructure, improve security and performance, reduce costs, and monitor service quotas. You can then follow the check recommendations to optimize your services and resources.
AWS Trusted Advisor analyzes your AWS environment and provides best practice recommendations in five categories.
The trusted advisor is enabled by default for errors and warnings.
