This document discusses approaches for migrating enterprise applications into OpenStack. It describes the orchestration approach using TOSCA (Topology and Orchestration Specification for Cloud Applications) to define application blueprints. These blueprints describe application topology, workflows, and policies. The blueprint is used by orchestration plugins to provision, configure, monitor and manage the application across various infrastructure like IaaS, containers, and configuration management tools. Real life use cases from major enterprises are also discussed. The document announces the upcoming availability of a Cloudify Composer tool for creating application blueprints with a simple web UI.
