Towards uniform management of multi-layered cloud services by applying model-driven development

In this paper, we utilize Model-Driven Development approach for managing arbitrary Cloud services. We define a metamodel of a Cloud service called CoPS, which describes a service as a composition of software/hardware elements by using three sequential models, namely Component, Product and Service. We also present an architecture of a Cloud Management System (CMS) used for automatic service management, which transforms the models from an abstract representation to an actual deployment. The approach is validated by realizing four real-world use cases using a prototype implementation. Finally, we evaluate its consolidation capabilities by simulating resource consumption and deployment time.
