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 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 disasters. The disaster alert such as Earthquake Early Warning can be caught by usual smartphone. And we control virtual machines status and virtual machines positioning on the private cloud fabrics by caught disaster alert notifications. 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 the experimental results on the prototype configuration.
