A Novel benefit model for virtual machine resources allocation

Virtual machine technology is widely used in cloud computing. This paper put forward a benefit model aimed at optimal allocation of virtual machines of cloud data center. Differentiate service levels according to the service response time, calculate profit and fines according to the satisfaction conditions of different service levels. When a service request is responded and completed within the specified time, then the profit of the service is calculated; if not, then the fines is calculated. Evaluate comprehensively the total benefits of service based on value of service benefit and fines calculated during a certain period of time. Dynamically adjusting resource allocation with the objective of maximizing total benefits is conducive to the realization of autonomous configuration of resources and to the improvement of the overall efficiency of the service.
