Koshien-Cloud: Operations of Distributed Cloud as a Large Scale Web Contents Distribution Platform

The cloud computing paradigm is now widely used thanks to its scalable on-demand resource management techniques. Since one of the most important challenges of cloud computing services is to stably provide their consumers with computing resources, it is necessary to investigate the performance of cloud computing services in actual operations. To study the realistic performance of cloud computing services, we propose in this paper deploying and operating a distributed cloud computing system as a web-based, nationwide image delivery service for the annual baseball championship game in Japan. Measurement results show that the proposed system has worked stably, though it raised some performance issues related to the highly loaded VM.
