The science and technology cloud is an important means to change the multi management, duplication, cross and inefficient problems of the technology service platform. It is also an important trend of the development of the information technology for the service platform of science and technology. Because the technology cloud is lagging behind the technology service platform, the integration of data resources and resource sharing are more complex than the discrete platform. Based on the technology cloud, it is a prerequisite to clear the data resources, service functions, user objects and operation patterns of the technology service platform. On the basis of the analysis of scientific and technological intermediary mode, public package mode and the operation mode of different forms of technology service platform, the data resource, service function and user object of the technology cloud platform are analyzed, and the operation mode of science and technology cloud under the government leading mode and the section under the leading mode of the enterprise are depicted. The research points out that the technology service platform data resources will be concentrated in the form of resource pool under the technology cloud model, and the technology service will reflect the "one-stop" service characteristics. The government led technology cloud operation mode and the enterprise LED technology cloud operation mode will be different.
