You can extend your application life cycles by using either extensibility actions or vRealize Orchestrator hosted workflows with extensibility subscriptions.
When a triggering event occurs in your environment, the subscription is initiated and the specified workflow or extensibility action is run. You can view system events on the event log, workflow runs in the workflow runs window, and action runs in the action run window. Subscriptions are project-specific, meaning they are linked to cloud templates and deployments through the specified project.
