Abstract: To solve the problems of frequent violation of Quality of Service (QoS) constraints,insufficient resource utilization,and low revenue of cloud application provider in cloud resource allocation,an optimal cloud resource allocation strategy for cloud application provider’ revenue was proposed.In this strategy,the cloud application provider obtained the probability distribution of visitor volume in a certain period of time based on experience.Then,based on the idea of newsvendor model for reference,the method of minimum loss expectation was adopted to calculate the optimal amount of cloud resource allocation.Fixed,segmented,and dynamic prices were common cloud resource pricing methods.Based on the above methods,the fixed price cloud resource configuration strategy,segmented price cloud resource configuration strategy and dynamic price cloud resource configuration strategy were designed.When visitor volume was random,the optimal cloud resource allocation amount obtained by this strategy could maximize the benefits of cloud application provider and make full use of cloud resources.There was no violation of the QoS constraint at the level of Infrastructure as a Service (IaaS) and Platform as a Service (PaaS).
