Abstract:  With development of cloud computing and virtualization, it is possible that one physical machine can be virtualized one virtual machine to support an application. In tradition, virtual machine placement just considers whether there is sufficient resource, ignoring the relationship of application type and physical resource status. This paper gives the concept of compute resource applicability, which means that the current status of computing resource is suitable for deploying which application type. When deploying an application, firstly we judge the application type and acquire the occupation of resource, then combine monitor data with the occupation to do static estimation and dynamic estimation. The optimal virtual machine placement policy can be achieved by compositing the results. The experimental results show that, the proposed solution could effectively improve the efficiency of application and the use ratio of resource, and shorten the response time of application.

Key words: cloud computing, virtualization, virtual machine placement, application type, computing resource applicability
