摘要：The advent of distributed processing has drastically increased the number of hosts required to support an enterprise level computing domain. Often, each application such as accounting, DNS or WWW service is allocated its own dedicated host for performance and security reasons. While this scenario is effective from an enterprise computing perspective, it poses several disadvantages. These disadvantages include: high hardware cost, significant 110 volt power consumption, significant cooling costs and a complex computing environment to manage. To combat these disadvantages the concept of virtual hosts has been suggested. This paper explores, through a case study, how virtualization could be employed in a live computing domain to reduce the number of physical host by a factor of 9 while still maintaining adequate performance/security metrics. Further, while offering the advantages of ease of management, reduced power/space/cooling requirements and improved fault tolerance/backup.
