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

我们将其最新设计的CMS-mini放在Run中，并模拟用户在满负荷的班级(40名学生，1名教师)中访问它。运行测试表明，与只能通过网络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。流量和数据库操作分析表明，Google App Engine免费提供的1个CMS-mini实例可以托管多达50门课程的完整材料。在本研究中，我们成功地将云计算技术应用于开发一个影响教育系统的关键情况响应系统。我们设计了新的系统，能够以标准化的格式输入用户的信息和教育材料，并设计了一个移动应用程序，与系统结合使用，允许通过移动设备访问，以响应用户的需求。我们成功地测试了系统的功能(导入内容、分发资料、收集报告、跟踪用户活动)。我们得出了一个估计的课程数量，这些课程可以在一个免费的云计算平台上通过Google Apps Engine提供服务。

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.
