The Research On The Pricing Of Cioud Computing Resources Based On Combinatorial Double Auction

Cloud computing is an computing model, which using Internet-media,-to provide users dynamically scalable virtualized resources, as cloud computing continues to evolve, the major companies are beginning to offer cloud computing services, cloud computing market size constantly expanded, but the current cloud computing market trading mechanism lack of flexibility, in most cases, IT companies have a fixed proportion of the pricing model, unable to meet the growing needs of diverse users. Firstly,I have reviewed the existing pricing theory, and secondly, from the initial auction price and the auction process dynamic pricing to improve traditional combinatorial double auction cloud resources pricing algorithm, using algorithm simulation analysis methods to study the effectivenesss of the improved model at superiority and the success rate of the auction and price stability.From the simulation, we found that the improved combinatorial double auction cloud resources pricing algorithm:1) increase the average utility of all buyers in the small-scale auction, while87.5%of the resource providers increase the average utility;2) at large-scale auction,83.5%of buyer increase the average utility, while75.8%resource providers increase the average utility, the difference of average utility between buyers and resources providers have reduced;3) in large-scale auction simulation, the average success rate have improved10%;4) in large-scale simulation of the auction, average transaction price of improved algorithm participants minus the amplitude is maintained at less than2, we can see that the improved algorithm has a basic price stability.In the case of domestic has few literature on cloud computing resources pricing, this paper proposed a cloud resource pricing method based on combinatorial double auction theory, to a certain extent, this paper compensate the gaps in the study, and has a great academic and theoretical significance; at the same time, the results of this paper, has a certain significance to the domestic IT companies which providing cloud resource,this paper also has important practical significance.
