TODO: Update UML with correct terminology. Update UML to add SDC Service Distribution

example of policies, blueprints, api calls. etc.

Day N: Control Loop Deployment

Control Loop deployment happens when an instance of a Service is created.

TODO flow diagram

Day N: Runtime Flow of a Control Loop

The following is a control loop message flow, across DCAE, Policy and App-C. The sections afterward will describe the process for designing, configuring and instantiating this flow.
