All ONAP scaling policies inherit from the tosca.policies.Scaling policy. A scaling policy may target any resource template or group in the model. When a scaling policy targets a group, this group scales out and in as a whole. Absence of a scaling policy for a resource implies that this resource should be instantiated once.
