摘要：The single service always difficult to meet theusers personalized requirements in cloud serviceenvironments, which needs by means of combining multipleservices to provide services for users. This paper proposes acloud service composition model based on virtual chord ring,and the virtual organization chord rings with QoSconstraints as the basis of service composition. The geneticalgorithm as the basic algorithm to obtain the global optimalcomposite service that meets the constraint conditions. Thesimulation results show that the service composition modelnot only has the advantage of global search to provideservices of satisfying user needs, but also has certainadvantages of shortening combination time, speeding up theconvergence speed and improving the precision. The servicecomposition model improves the efficiency of servicecomposition
