摘　　要：为了提升高校学生的自主学习能力,依托云计算的相关技术,合理整合软、硬件资源,构建一个激发学生学习兴趣、有助于教师辅导与答疑、简化考核与管理流程、真实反映学习效果的云端学习平台。本文通过虚拟化技术实现桌面、服务器及存储的虚拟操作,以便提高资源利用率与共享性;引入分层设计思想完成弹性扩展、实时播放视频媒体的直播操作,以便提高视频播放效率;在分布式存储系统的基础上,运用分布式B树的存储结构,将数据信息进行分类存放,以便提高系统信息的检索速度。In order to improving Self-study＇s ability of college students, a study platform based on cloud computing is built,which depended on Cloud Computing technology, integrated software and hardware resource, inspired student＇s learn interesting, contributed to teacher＇s guidance and answer, simplified procedure of checking and management, reflected really study effect. The paper used virtualization technology to realize virtualized operation of desktop and server so that improving resource sharing. It adopted multi-layer construction thoughts to finish efficient live video. The classified data information was stored based on storage structure of distributed B-tree, in order to improving retrieve speed of system information.
