AWS CloudFormation StackSets launches ListStackSetAutoDeploymentTargets API that allows customers to list existing target Organizational Units (OUs) and AWS Regions for a given stack set. With this launch, customers get visibility into the list of Regions where StackSets will auto-deploy stacks when a new account is added to target OUs. Customers no longer have to log into individual accounts under a given OU to get this information. Customers instead can get this Region combination for all target OUs of a given stack set in a single preview.
