Cloud systems are difficult to assess due to the relevance of modeling and its large-scale, complex structure, highlighting the dynamic and powerful layer. To solve this problem, the cloud system evaluation model is proposed based on queuing Petri network. It can efficiently model and simulate complex cloud system due to its powerful combination of quantitative evaluation and behavior description of the theoretical characteristics of queuing theory and Petri nets. On the basis of the model, we further increase the quantitative analysis and evaluation system cloud systems, and simulation of cloud systems, massively parallel dynamic service environments. Experimental results show that, queuing Petri network can effectively reflect the architectural features of various cloud computing system performance perspective, services.
