在本研究中，我们建立了一个灾难恢复的框架，如对地震和海啸灾害的电子学习环境。我们构建了一个基于IaaS架构的原型系统，该原型系统由多个私有云计算结构组成。这些私有云结构被构造为在VPN连接下操作一个大型私有云结构。分布式存储系统构建在每个私有云结构上，其处理方式几乎与同一块设备（如一个大型文件系统）相同。要使LMS（学习管理系统）工作，我们需要靴子虚拟机。虚拟机从存储到分布式存储系统中的虚拟磁盘映像引导。分布式存储系统将能够保持运行作为一个大的文件系统时，一些私有云结构不工作的任何麻烦。我们认为，我们的云间框架可以继续工作，在灾后的情况下的电子学习环境。在本文中，我们展示了我们的跨云合作框架和原型配置上的实验结果。
In this research, we have built a framework of disaster recovery such as against earthquake and tsunami disaster for e-Learning environment. We build a prototype system based on IaaS architecture, and this prototype system is constructed by several private cloud computing fabrics. These private cloud fabrics are constructed to operate one large private cloud fabric under the VPN connection. The distributed storage system builds on each private cloud fabric, that is handled almost like same block device such as one large file system. For LMS (Learning Management System) to work, we need to boot virtual machines. The virtual machines are booted from the virtual disk images that are stored into the distributed storage system. The distributed storage system will be able to keep running as one large file system when some private cloud fabric does not work by any troubles. We think that our inter-cloud framework can continue working for e-Learning environment under the post-disaster situation. In this paper, we show our inter-cloud cooperation framework and the experimental results on the prototype configuration.
