Abstract: According to the characteristics of multi-sources information service in cloud business,a service schema for multi-sources information service in cloud business based on the analysis of the classical service schema in current business activities was proposed.To solve the pricing problem of resource allocation under this service schema,three different models for service vendors,service customers,and the service environment were built,and the coordinated solving methods were also proposed.The different policies for resource allocation were compared under different scale of service customers.The experiment results showed that the service vendors and customers could get a higher utility with the increasing of the quantity of the service customers under the circumstance of ensuring the income of the third party.
