大学の情報サービス麻痺にクラウドとマッシュアップで対応する学習支援システムの開発

我们把CMS-mini在其最新的设计运行和模拟访问它的用户在一个类与全容量（40名学生+ 1名教师）。运行测试表明，使用移动的设备下载的内容降低了平均资源利用率的情况下，访问时，只能通过网络接口。流量和数据库操作的分析表明，它可以托管多达50门课程的完整材料为1个CMS-迷你实例免费提供从Google App Engine.在这项研究中，我们成功地实施了云计算技术，开发了一个系统，以响应影响教育系统的关键情况。我们设计的新系统能够使用标准化格式导入用户信息和教育材料，还设计了一个与系统结合使用的移动的应用程序，允许通过移动的设备访问，以响应用户的需求。我们成功地测试了该系统的功能（导入内容、分发材料、收集报告和跟踪用户活动）。我们估计了可以在Google Apps Engine的云计算平台的一个免费实例中提供的课程数量。

We put CMS-mini in its latest design in run and simulated access to it by the users in a class with full capacity (40 students + 1 instructor). The run tests showed that the use of Mobile devices to download the contents lowered the average resource utilization compared with the case when access was only possible through the web-interface. Analysis of the traffic and database operations shows that it is possible to host the complete materials of up to 50 courses for 1 instance of CMS-mini offered fro free from Google App Engine.In this study, we successfully implemented Cloud Computing technology in developing a system for response to critical situations affecting the educational system. We designed the new system with capabilities to import the information of the users and the educational materials using standardized formats, and also designed a mobile application to be used in conjunction with the system to allow access via mobile devices in response to the users' needs. We successfully tested the functions of the system (importing contents, distribution of materials, collecting of reports, and tracking users' activities). We reached an estimation of the number of courses, which can be served in one free instance of Cloud Computing platform from Google Apps Engine.
