The concept of cloud computing was first put forward in 2007. Efficient operational capability, infinite storage capacity and effective allocation and dispose of resource are the greatest advantages of cloud computing. After put forward, more and more people begin to study cloud computing, especially in universities which apply cloud computing to the construction of superior resource sharing platform positively. This research put forward a superior resource sharing platform which can realize the informationization, networking and automation of education, through a further study of existing superior resource sharing platform. The platform can provide a strong technical support for a better and faster service, a rapid development and a major revolution in universities. Applying cloud computing to superior resource sharing platform, this research put forward a superior resource sharing platform based on cloud computing. This platform can integrate service information resources of education and improve service quality of universities. Public education information service platform based on cloud computing can be realized by analyzing and studying characteristics of cloud computing and superior resource sharing. Practices show that this platform made great progress compared with information service of traditional education in respects of informationization, networking, reducing of education cost and flexibility. It could be argued that efficient computing capability and powerful computing and storage capacity are fully manifested on public education information service platform, making an overall improvement of superior resource sharing for education.
