A Metadata-driven Cloud Computing Application Virtualization Model

In order to meet the requirements of standardization of virtualization in cloud computing platform, improve the flexibility and expansibility of the system and enhance the capability of management-control of the platform, by means of introducing the features of decoupling and semantic of metadata, a Metadata-driven Cloud Computing Application Virtualization Model(MCCAVM) in software level is proposed in the paper based on Turing machine model and Von Neumann computer architecture. The model achieves the complete life cycle management of the capabilities and services. Based on the formal definition, analyzing the hierarchical structure with multi-role and multi-dimensional view, the paper proposes a Metadata-driven Cloud Computing Application Virtualization System(MCCAVS). Taking the production of virtual cloud storage service as example, this paper gives formal analysis of system running and compares with other relating work. The results show that the model presents good reference on the construction of cloud computing application virtualization platform.
