Unsurprisingly, to define a Control Loop Type in TOSCA, we must first define a number of Control Loop related concepts that we can use in all control loops.

Fundamental TOSCA Concepts for Control Loops

The following TOSCA concepts are the fundamental concepts in a TOSCA Service Template for defining control loops.

The TOSCA concepts above may be declared in the TOSCA Service Template of a control loop. If the concepts already exist in the Design Time Catalogue or the Runtime Inventory, they may be omitted from a TOSCA service template that defines a control loop type.

The Yaml file that holds the  Definition of TOSCA fundamental Control Loop Types is available in Github.

is made up of several components, those which represent applications, those which represent dynamic config schemas, and the actual node_templates which makes up the loop itself.
