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

我们将CMS-mini的最新设计进行了运行，并模拟了用户在一个满负荷的班级（40名学生+ 1名教师）中对它的访问。运行测试表明，与只能通过web界面访问的情况相比，使用移动设备下载内容降低了平均资源利用率。通过对流量和数据库运行情况的分析，b谷歌App Engine免费提供的CMS-mini实例可以托管多达50门课程的完整资料。在这项研究中，我们成功地将云计算技术应用于开发一个系统，以响应影响教育系统的关键情况。我们设计的新系统能以标准格式导入使用者的资料和教材，并设计了一个流动应用程式，配合系统使用，让使用者可透过流动装置接达，以回应使用者的需要。我们成功测试了系统的功能（导入内容、分发资料、收集报表、跟踪用户活动）。我们估计了课程的数量，这些课程可以在谷歌Apps Engine的一个免费云计算平台实例中提供。

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.
