A Case Study of Cloud Computing Service Models for the General Computing Environment in a University

Cloud computing technology has emerged as the basic infrastructure technology in the 4thindustrial revolution and has been utilized in various fields. Therefore, the authors analyze the requirements of academic and administrative affairs, education affairs, and affiliated institutions in the university. Proposed cloud computing service models in the universities are implemented using an OpenStack in CentOS 7.3 and Windows. To evaluate the performance, the author compares various performance factors including launching time, booting time, ping time, and software installation time. Lastly, the economic benefits in the university will be evaluated by comparing the adoption cost, maintenance cost, and total cost between the existing client-server system and cloud computing system. Future work aims to implement a cloud computing system that can be applied to the entire university. Finally, based on these studies, the authors will implement a regional base cloud system that can connect all universities in the region with one cloud computing system.
