云资源定价策略的设计与实现

loud computing market model has begun to form and grow，at the same time, cloud computing resources transactions has become a main way of cloud resources supply and lease between cloud resource providers and demanders. So that how to use the price mechanism guiding role and develop a reasonable price mechanism to achieve a fair trading of resources has become a serious problem,especially in an open dynamically changing cloud market situation.In order to solve the existing problems this papper proposed a dynamic pricing algorithm based on continuous double auction under the premise of analysis of existing cloud resource pricing algorithm. Considering the cost, supply and demand, time, quality and other factors, the pricing formula and pricing algorithm in pseudo-code are given in both case of reference pricing strategy and agent pricing strategy. Cloud Computing trading simulation system has designed to prove the algorithm is fair reasonable and effective.
