The introduction of cloud computing can realize the resource sharing and managing between different educational institutions. Through the cloud, every educational institution can implement the management of the platform. When one institution gets access to or modify the resources, other educational institutions on the platform are able to see the updated information in time. The application of cloud computing is of great significance for the educational industry which requests higher and higher in the sharing of information resources. The paper analyzes the existing researches on high-quality resources sharing at abroad and home, and illustrates that the countries but China the mainly focused on exploring the open course resources as well as studying educational resources sharing platform in cloud computing environment through the cooperation of the school and enterprise. While researches in China mainly focused on the opening of national excellent courses, and most researches on the application of cloud computing in the sharing educational resources are still in the theoretical research stage. And the existing few practical applications are the constructed by using public cloud platform; On the basis of analyzing the research status of sharing high quality resources at home and abroad, this study introduces the sharing platform design of high-quality resources in cloud computing environment. Firstly a sharing earning model is established based on cloud computing,. Then design the sharing platform of high quality resources of The Principle and Application of Data in cloud environment and analyze the design idea of platform. And the architecture and functional structure are designed. Finally Sina App Engine is chosen to build the platform of sharing high-quality resources in cloud computing environment.
