bull An orchestration service to create and manage the lifecycle of OpenStack cloud application ie anything-as-a-service (XaaS)

bull Uses JSONYAML based parameterized HOT template to model the customizable cloud application made of software configurations and infrastructure

bull Represent each provisioned cloud application as
