By using the method of system dynamics analysis and using the computer system simulation method, the business requirements and construction scale of the cloud computing virtual machine are studied from the perspective of the system, and the key factors affecting the number of cloud computing virtual machines are found out. Further, on the decisive factors for calculating the size of resource pool, this paper proposes the basis and concrete realization of optimizing the estimated construction scale by using the theory and method of mathematical statistics, gives the regression equation and verifies the credibility of the regression equation. Therefore, effectively analyzing the influencing factors of the construction scale of cloud computing system, it can be used successfully to estimate the construction scale of cloud computing virtual environment, avoid the blindness of intuitive simple linear deduction, and optimize the realization of green energy saving. Meanwhile, the theory of promoting cloud computing construction Research and practice a certain guiding role.
