Evaluation of Bottlenecks in an Educational Cloud Environment

Many companies and universities make use of a Cloud-based educational environment. Such environments, however, usually require a high-performance server, making them rather expensive. In this study, we use low-cost PCs to construct a Cloud-based educational environment. But compared with a high-performance server, performance drops as the number of instances increases. In this paper, we investigate the bottlenecks in running instances.
