Study on Cloud Computing and its Application in Distance Education System

In traditional distance education system,teaching resources is usually a simple distribution,share of poor and low efficiency.There are some defects of duplication of resources,weak system expansion capacity,the poor configurability,and expensive cost.The paper through the research on cloud computing and the characteristics of distance education system is designed based on the new cloud computing system,the logical structure of distance education,the overall structure and core modules.The new system has made much progress on educational service,teaching resources share,configurability and flexibility which can guarantee the large-scale teaching activities.
