Abstract
The use of cloud computing is becoming widespread, but systematic study of its managerial implications is lacking. This paper examines cloud computing in the context of other major changes in Information Technology (IT) and explores the revolutionary transformations and challenges which bring to IT management. Cloud computing has a high reliability, low cost and good availability. With the increasing use of technology in modern era, there is a growing requirement of information technology infrastructure management. Over some decades in the past, organizations have put their efforts in the development and application of information technology to collect, analyze and process the data. Various computing paradigms have been employed for the purpose and needs have emerged for enormous infrastructure.Cloud Computing is evolving as a key computing platform for sharing resources that include infrastructure, software application and business processes. Virtualization is a core technology for enabling cloud resources sharing (Liang et al. 2009). Virtualization refers to the abstracting of a form of technology away from its original environment. The benefit derives from being able to redeliver it in a virtual (or “logicalâ€) form capable of the same functionality as the original, but with greater flexibility (Tata Communication White Paper 2012). This paper presents how Cloud Computing service model – Infrastructure as a Service (IaaS) can be used to meet the increasing demands of the Information Technology Infrastructure Management and how Cloud Computing paradigm can prove to be future solution for such systems. With IaaS, IT services can be delivered as a subscription service, eliminating up-front costs and driving down ongoing support costs.

THE RISE OF A NEW PHENOMENONCompetition on the global market forces many organizations and enterprises to make use of new technology and applications to reduce time and at the same time cut down the costs of their Information Technology (IT) – infrastructure [3]

Virtualization is the key to Cloud Computing; it is not a vague concept since virtualization is the technology allowing the inception of an intelligent abstraction layer which decouples the physical hardware from the operating system to deliver greater IT resources utilization and flexibility [13]
Summary
Competition on the global market forces many organizations and enterprises to make use of new technology and applications to reduce time and at the same time cut down the costs of their IT – infrastructure [3]. Cloud Computing even refers as a new paradigm and emerging technology that flexibly offers IT resources and services over the Internet [4]. Everyone has a conception on what is Cloud Computing. Cloud Computing has the potential to revolutionize the mode of computing resource and application deployment, breaking up the traditional value chains and making room for new Information Technology Infrastructure Management – maintained off premises i.e. a third party owns and manages public cloud services and consumers using these services pay for it as per-use basis, they do not possess resources in the cloud. The paper starts by analyzing the IT pendulum of centralization and decentralization, after this contextual overview, briefly discusses the application of cloud computing as a computing paradigm to Information Technology Management
