Abstract:Cloud computing is emerging accompanied by the emergence and development of cloud computing,and it is a new field to research cloud computing development pattern. In this paper, we research the development model of cloud computing economy from the perspective of business ecosystem. Firstly, we design of a cloud computing ecosystem model through drawing lessons from the research results of the business ecosystem. Then we put forward cloud computing development dynamic mechanism under the perspective of business ecosystem according to the characteristics of business ecosystem, and we design theoretical model and mathematical model of cloud computing development pattern through business ecosystem structure characteristics and the logistic growth model under the ecological perspective.
