The Service Broker provides a simplified and efficient catalog that you provide to your users. You use the catalog to manage the available catalog items and the how and where they are deployed.

For a cloud administrator, Service Broker is the streamlined user interface that you provide to your development operations and other teams. You import the machine and application blueprints and templates that then need, and add governance in the form of projects to control who can deploy what resources, and to control where the resources are deployed.
