Proposal for BYOD Based Virtual PC Room

Currently, smart devices such as smart phones and tablets are becoming more popular than PCs. In the future, almost all users except developers will be using smart devices for business instead of PCs. Students will also use their own smart devices in school. Using such a Bring Your Own Device (BYOD) method, the costs of computing devices will be drastically reduced relative to conventional rooms filled with PCs. However, current smart devices do not have enough functions to match the power of PCs. Thus, we propose a BYOD based virtual PC classroom using the cloud. In the proposed method, the cloud provides the PC functions currently lacking in non-cloud smart devices, allowing the realization of all functions needed in practice. In other words, we have developed an educational cloud based on a supersaturated private cloud, which is defined as a cloud in which a much greater amount of logical resources than physical resources are allotted. Supersaturated clouds can run up to 10 times more instances than conventional clouds. Therefore, the cost is reduced to only one-tenth of conventional costs. Furthermore, we have developed several menu based tools to reduce required key strokes.
