Abstract: This paper studied the QoS quantitative evaluation method of cloud service composition.On the basis of the characteristics of combined cloud service environment of virtual dynamic nature and random service,this paper put forward the realization frame of cloud service composition based on BPEL workflow,established the combined cloud ser-vice process net(CCSPNet) based on the theory of stochastic Petri net,evaluated the performance with Markov process,and proposed the six-dimensional QoS evaluation system and the QoS quantitative evaluation method of cloud service composition combined with the CCSPNet module.The application example shows that the new method has better dynamic adaptability and flexibility and can satisfy QoS evaluation requirement of cloud service application environment effectively.

Key words: Cloud computing,Service composition,Markov process,QoS evaluation
