Activating AppRegistry for a workload
Using AppRegistry is optional, and AWS Business and Enterprise Support customers can activate it on a per-workload basis.
Whenever Discovery support is turned on and AppRegistry is associated with a new or existing workload, AWS Well-Architected Tool creates a service-managed attribute group. The attribute group Metadata in AppRegistry contains the workload ARN, the workload name, and the risks associated with the workload.
When Discovery support is turned on, any time there is a change to the workload, the attribute group is updated.
When Discovery support is turned off or the application is removed from the workload, the workload information is removed from AWS Service Catalog.
If you want an AppRegistry application to drive the data fetched from Trusted Advisor, set your workload Resource definition as AppRegistry or All. Create roles for all accounts that own resources in your application following the guidelines in Activating Trusted Advisor for a workload in IAM.
