Provisioned product referencing is now available in AWS Service Catalog

AWS Service Catalog now supports referencing Service Catalog provisioned product outputs in new provisioned products or AWS CloudFormation stacks. Provisioned product outputs, such as a VPC identifier, can now be made available as inputs to dependent provisioned products and stacks. This saves time building applications that have dependencies on existing infrastructure, such as a VPC, S3 bucket, or RDS database.
