SECURITY ISSUES IN DELIVERING INFRASTRUCTURE AS A SERVICE IN CLOUD COMPUTING AND BUSINESS - Literature review Example The theme of cloud computing is that all computational resources and assets are offered by the cloud service providers to the remote users all around the globe as a service. It does not require the users to have proper knowledge and proficiency in a particular domain or technology in order to manage the resources and user can access them through internet. Cloud computing is a fairly innovative 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 towards a particular business and are commercial so it does not supports the users with complex and bigger requirements and rel atively 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 operating 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 service is usually provided according to some measure of QoS(
