Building of a Disaster Recovery Framework for E-learning Environment Using Private Cloud Collaboration

In this research, we have built a framework of disaster recovery such as against earthquake, tsunami disaster and a heavy floods for e-Learning environment. Especially, our proposed framework is based on private cloud collaboration. We build a prototype system based on IaaS architecture, and this prototype system is constructed by several private cloud fabrics. These private cloud fabrics are operated as a large private cloud fabric. The distributed storage system builds on each private cloud fabric; that is handled almost like same block device. For LMS (Learning Management System) to work, we need to boot up virtual machines which installed LMS. The virtual disk images of each virtual machines are stored into the distributed storage system. The distributed storage system will be able to keep running as a large file system. We can control the virtual machines’ status and virtual machines positioning on the private cloud fabrics by the private cloud collaboration controller with a smartphone communication. The private cloud collaboration controller is able to grasp disaster alert notifications. The disaster alert notification can be caught by a cellphone carrier via smartphone function. We think that our private cloud collaboration framework can continue working for e-Learning environment under the post-disaster situation. In this paper, we show our private cloud collaboration framework. And next, we show the experimental results on the prototype configuration.
