SECURITY ISSUES IN DELIVERING INFRASTRUCTURE AS A SERVICE IN CLOUD COMPUTING AND BUSINESS - Literature review ExampleThe theme of cloud computing is that all computational resources and assets are offered by the cloud supporter providers to the remote users all around the globe as a returns. It does not require the users to have proper knowledge and proficiency in a accompaniment domain or technology in order to manage the resources and user can access them through internet. Cloud computing is a fairly advanced computing model and has been prominent in the field of information technology over past years. The cloud computing model enables the subscribers to utilize the computing resources and assets in the time of need, without investing higher amount of money and frees them from the worries about the complication involved in adopting other options. Nevertheless the huge number of implementations that have gotten so much higher reputation among the community of IT are oriented tow ards a particular rail line and are commercial so it does not supports the users with complex and big requirements and relatively little financial resources. (Vincenzo D. Cunsolo et al, 2010, Juan D. O sorio, 2012)Cloud computing that is a modern business paradigm, involves the provision of extraordinarily scalable computing assets as a service to individual subscribers or the organizations. Companies are now adopting a trend of replacing the older IT infrastructure by consuming the Infrastructure as service model offered by cloud computing paradigm in order to get better scalability of computing resources and to make lesser direct cost. The fundamental business of an infrastructure as a service cloud is to set up an instance of virtual machines, on-demand, for agreed period of time. The specifications (e.g. total memory storage, required operating system, executables) of the virtual machines are decided in a agreement between the cloud service provider and the consumer and servi ce is usually provided according to some broadsheet of QoS(
