Hardware Virtualization towards a Proficient Computing Environment

In the recent few years Server Virtualization and Green Information Technology have become very popular and are fast becoming the norm in organizations of all disciplines and sizes. Today, different methods of energy savings are in use and in great demand. One of the newest methods in the IT to control the pollution of the environment and the greenhouse effect is Green IT that is directly connected with the Virtualization of Hardware Resources. Virtualization is the presentation of an environment to one layer in an information technology stack that abstracts or represents a lower layer. It makes it possible for the IT professional to run a number of machines on a single physical machine. In this study we elicit the concept of Hardware Virtualization. We illustrate the procedure of Hardware Virtualization using a real-world example and then we emulate a virtualized infrastructure to contrast against the physical infrastructure on the basis of CPU utilization. We have used the VMware Workstation 7.1.0 as a software tool for virtualization and AVG PC Tune Up 2011 to present the difference in CPU utilization before and after virtualization. This paper helps to identify the main reasons for the growing need for data centre virtualization. The results in this paper show that a virtualized infrastructure can potentially increase the CPU utilization by a significant margin, thereby suggesting an efficient and faster way of resource utilization, saving processing time, reducing the cost incurred in building separate physical servers and furthermore reducing the power consumption.
