Cloud virtualization: A potential way to reduce global warming

The greatest environmental challenge today is global warming, which is caused by carbon emissions. A report by the Energy Information Administration says that about 98 percent of CO2 emissions (or 87 percent of all CO2- equivalent emissions from all greenhouse gases) can be directly attributed to energy consumption. The major challenge of many organizations today is a desire to operate in a “green” manner, publishing principles for environmental practices and sustainability on their corporate Web. In addition, many companies are now paying some kind of carbon tax for the resources they consume and the environmental impact of the products and services they produce, so a reduction in energy consumed can have a real financial payback. In this paper, we focus on reduction in energy consumption over the full equipment life cycle as the prime motivator for “green” application design; with energy reduction as the best measure of “green-ness”. Green IT refers to the study and practice of using computing resources in an efficient, effective and economic way. The various approaches of the green IT are Virtualization, Power management, Material recycling and Telecommuting. In which Virtualization platforms can run across hundreds of interconnected physical computers and storage devices, to create an entire virtual infrastructure. Cloud computing is the concept of equal sharing of resources among nodes. Cloud virtualization refers the process of running two or more logical computer systems on one set of hardware with equal sharing of resources. The challenge of the existing system is reduction of efficiency due server virtualization. In this paper, we propose a new system that connects more number of nodes with minimum number of servers. The sole motivation of this paper is reducing energy consumption using cloud virtualization clique star cover number technique.
