In allusion to the characteristics of the business process management,this paper provided an implementation framework of composite cloud service. Based on the theory and modeling methods of stochastic Petri nets,it discussed the methods for the transformation from the BPEL business process to the composite cloud service process net model. In view of the idea of SOA and the dynamic changeable requirements,it designed a two-dimensional and multi-levels reliability evaluation framework of cloud service composite,and introduced the reliability analysis method based on Markov process and the reliability dynamic assessment method based on equivalent reduction. The application example analysis results show that the method is more dynamic adaptability and flexibility,which can effectively meet the reliability evalution of the cloud service demand.
