In this paper, we design a cloud-based workflow platform, which can provide services for each campus application based on the same set of platform. It can reduce development costs, reduce the costs of purchasing software, hardware, storage and network, reduce the costs of data backup, system management and maintenance. It also can achieve the maximum degree of utilization of the platform. Each application can register its service on its needs conveniently. It can not only enable reuse, but also provide a platform and data basis for the work service hall. Currently the workflow cloud platform has been used in all aspects of personnel, scientific research, information work, and etc. It will improve and enrich this platform to develop more applications superimposed and provide more and better information resources and services for staff.
