An evaluation of private cloud system for desktop environments
Mikifumi Shikida, Kanae Miyashita, Mototsugu Ueno, Satoshi Uda · 2012
We design our computing environment as a centralized system since our university's foundation. By our system, users can connect with their desktop environment on a server at anywhere in the campus. Two years ago, we have built up a new private cloud system. For our system we adopted a combination of three virtualization products: VMware vSphere, Citrix XenApp, and Microsoft Application Virtualization. Our users consist of graduate student, faculty, and staff in the whole university. We can increase efficiency of resource use because they have a different use pattern, respectively. Our other goals are increase of usability and decrease of operation costs. In this paper, we describe the analysis of statistics. Although we have increased average CPU utilization of each server, it is not adversely affected the user experience. We realize that only several tens of servers are enough for use in the whole university. Finally, we discuss the effects of private cloud system in university.
