The advancement of business and social practices based on information and communication technologies (ICTs) in the last few decades has transformed many, if not most, economies into economies and businesses into e-businesses. For economies, ICTs are increasingly playing a critical role in transforming and generating economic opportunities. Technology has a potential to create sustainable business and society both in grim and green economic times. Especially, the recovery from the current economic crisis is going to lead to more greener and energy efficient industries. Data centers are found to be major culprits in consuming too much energy and generating higher level of CO in their overall operations. In order to handle the sheer magnitude of today s data, servers have become larger, denser, hotter, and significantly more costly to operate using more power than being used earlier. This paper determines the properties and attributes of green IT infrastructures and the way they will be helpful in achieving green sustainable businesses. The proposed attributes and characteristics of green IT using Virtualization technology are very productive and efficient for data centers in making them more energy efficient and green, hence reducing the emission of greenhouse gases so that their overall effect on global warming can be reduced or even eliminated. The proposed attributes indicate the qualities of green IT to enhance the proper utilization of hardware and software resources available in the data center.
