Pattern-Based Deployment Service for Next Generation Clouds

This paper presents a flexible deployment service for cloud computing. The service facilitates the specification and the execution of cloud deployment plans for applications. An application is described through a pattern, an abstract view that captures the logical view of the application and its mapping into cloud resources. The services instantiate the pattern in the cloud and allows for runtime updates of the deployment. The service is accessible through a RESTful interface. We identify the requirements for the service, describe its interfaces and show several case studies that capture the main features of the service.
