构建开放教育云系统的要点和难点

The Key Points and Difficulties in Building Open Education Cloud System

信息技术对教育发展具有革命性影响,而云计算又颠覆了传统的计算模式。基于云计算在商业领域产生的巨大效应,使得这一概念被疯狂炒作,在教育领域也涌现了一批打着云计算旗帜的企业和产品,但这些产品仍未摆脱传统模式羁绊,未能达到云计算所指向的高度。从云文件系统、计算农场、角色定义、用户层次等几个理念探讨构建开放教育云系统的要点和难点问题。

Information technology has revolutionary impact on education development just as cloud computing has overturned the traditional calculation mode. As a consequence of the huge effect of cloud computing in the business world, its concept has been greatly hyped. In education domain, many enterprises and their products sprung up in the disgise of cloud computing. Nevertheless, without reaching the intended capacity of cloud computing, they have not yet broken the fetters of the traditional mode. In the present paper, the key points and the difficulties in building open education cloud system are discussed from the perspective of the related notions like cloud file systems, calculation farm, role definition, user hierachy and so on.
