Title Research of pricing of virtual resource in the cloud computing environment
Abstract With the development of the network and the Internet, cloud computing appear more frequently in our life. Study of pricing of cloud computing environment is conducive to the further development of the cloud resource providers and cloud computing. The pricing is affected by the cloud resource allocation policy. This paper involves the cloud resource allocation strategy based on user needs, and the current system of various performance indicators for cloud computing resources dynamic allocation to get the best performance. Nowadays most of the study about the cloud resource allocation optimization based on the fixed capacity among the existing papers. We do the study for the merits of the dynamic pricing from the perspective of inpidual tenants and cloud providers respectively with fixed capacity as a benchmark.Through uniting the capacity and pricing,we can reduce the power consumption of the cloud service providers in order to maximize their revenue.We combine the problem of optimizing the capacity and pricing to transform into a mathematical optimization problem with setting the capacity of the data center and the pricing of virtual resources as two interdependent variables.We obtained the relationship function between the optimal capacity and it’s price on the basis of given price of a virtual machine.According to this function,we get the optimal capacity and resource price.It shows that the algorithm we proposed receives a better revenue than the older one.
