Resource-sharing based on network platform is an extremely important platform for utilizing all sorts of resources, and the state has put a lot of efforts into corresponding construction, as is testified by mushrooming resource-sharing platforms of different types belong to major colleges and universities, enterprises and government departments, which, however, are of old design concepts, leading to problems of being closed and uneven distribution etc in most cases of resource-sharing, and utilization rate of resource is affected to a large extent. Cloud computing, which originally attracted worldwide attention as a business mode, whose rapid development proposes new workable solution for existing methods of platform design: platform construction based on cloud computing will realize more resource-sharing to a possible extent, also, with high scalability and good characteristics of remote interaction management. In the mode of cloud computing, storage, access and sharing of resource are extremely stable and reliable, maximizing resource-sharing by means of its powerful computing capacity. This new type of resourcesharing platform can stimulate most effective use on the part of users. Through introducing basic concepts of cloud computing and resource-sharing platform, this paper then analyzed application value and status of cloud computing in constructing resourcesharing platform, laying certain theoretical basis for constructing relatively complete resource-sharing platform by perfecting design ideas and combining with existing cloud computing platform.
