The present disclosure involves systems and methods for compiling abstract application and associated service models into deployable descriptors under control of a series of policies, maintaining and enforcing dependencies between policies and applications/services, and deploying policies as regularly managed policy applications themselves. In particular, an orchestration system includes one or more policy applications that are executed to apply policies to a deployable application or service in a computing environment. In general, the orchestration system operates to create one or more solution models for execution of an application on one or more computing environments (such as one or more cloud computing environments) based on a received request for deployment.
