Model driven orchestration allows modeling of services and applications using a declarative and descriptive language, then to operate the application using the model. This includes deployment of the application, healing failures, scaling and others. Instead of executing manually crafted workflows, the orchestrator creates dynamic execution workflow graph, based on the application model. Each node of the graph triggers a corresponding lifecycle operation execution, while the orchestrator keeps track and stores state in a context object allowing passing information from one operation to another.

• Cloudify Orchestrator creates a deployment graph, at run time. Executing the Install workflow traverses thru the graph, and executes relevant lifecycle operation interfaces.
