In the past days when computers as well as computer users were less, the use of these machines was limited and depends on the technology. Now a day’s technology is growing rapidly so the use of computers and its peripherals. Startup companies and organizations are not so self-sufficient to buy the entire required infrastructure at a time so they take help of utility computing.
Utility computing is defined as a service provided in which service provider avails computer resource as well as infrastructure management to the customers according to need and charge them for their specific usage in place of flat rates (Klvac, 2002).
Utility computing includes computation or processing devices, storage devices including hardware and software as a meter billing service as shown in Figure 1. This repackaging of computing services became the inspiration of the shift to “on demand” computing, code as a service and cloud computing models that more propagated the thought of computing, application and network as a service (Fox and Pallickara, 2013).
