AWS Cost Management services now support AWS Service Catalog AppRegistry resource tags to help customers better manage, analyze, and optimize their application related resource costs. Starting today, customers who use AppRegistry to define their applications can have the new AWS application tag applied to all their application resources. This tag is provided by AppRegistry, and allows customers to group and view resource collections across their AWS accounts as applications that they define. The application tag is automatically activated as a cost allocation tag so that it can be used in various cost management services to analyze, manage, and optimize application-related resource costs.
