Provisioned product outputs are now available in AWS Service Catalog
AWS Service Catalog now supports obtaining outputs from a Service Catalog provisioned product in an AWS CloudFormation template. Product outputs provide the interface from one product to another. With this new feature, administrators and developers can easily refer to those outputs in order to combine the products needed for their applications, which saves time building applications that use more than one product, such as a three-tier web application.
