Abstract

There has been rapid expansion of the information technology due to contribution to emission of carbon dioxide. The cloud computing technology has been perceived to present solution to various studies that try to investigate on the most appropriate ways of reducing the carbon dioxide gas emissions. The current study aimed at investigating the adoption of virtualization in cloud computing as a means through which the green computing can be achieved. According to the paper virtualization among its many process helps in curtailing equipment required through cloud computing resources to facilitate adequate use of resources to make use of energy and assets.

Virtualization

Virtualization refers to the creation of virtual version of a resource that divides the resource into single or multiple execution environments. This is critical in cloud computing as it enhances scalability since every server is allocated enough storage and computing power needed by a client. The increased demand for user capacity requires more power and capacity (Bianchini et al., 2012).

Virtualization is changing the IT environment where most companies have been able to adopt it as a measure that allows for better utilization of hardware and reduction of costs (see Figure 1). One of the major benefits of virtualization that go unnoticed is the green computing (Sherringham, 2011).
