Based on the view of "process determining product quality", this paper systematically studies the service process model, formal modeling and the formal method of service process improvement in order to improve the execution efficiency of service process and improve service quality. Firstly, according to the definition of software process, the definition of different granularity of service process is given. And deeply studied the cloud computing service process of the system process model, cloud computing early implementation process model, cloud computing fine-grained service process model and cloud computing service evolution process model. Secondly, in order to describe the service process of cloud computing more accurately, the service process model is formalized based on the weighted Petri net, and the algorithm of resource allocation in the service process is given. Finally, based on the proposed method of service process modeling, this paper further studies the updating operation of the service process model established by this method. To sum up, this paper systematically studies the different granularity of cloud computing service process, and the service process modeling and improve the operation of the in-depth research, and then for the service process simulation, control and automation to lay a foundation for improving the service quality and efficiency of cloud computing is of great significance.
