Abstract

Cloud Computing is the internet established enabler for sharing of technological infrastructural resources, software and digital content, allowing them (Infrastructure, Platforms, Software) to be presented on pay-for-use basis, like any utility service. The exponential growth of computing capacities, the extraordinary growth in the consumption of digital contents, then the explosive growth of applications have triggered the emergence of cloud computing. It is probable to herald a new wave of Computing and is probable to wield enormous influence on how IT services will be consumed in future. Cloud Computing conveys down dramatically the cost of IT use, in addition to providing flexibility in terms of large capacity-on-demand coupled with higher reliability. As it does not call for large capital expense and need for highly skilled IT professionals to build and manage the infrastructure, range and scale of Cloud applications are bound to grow enormously, even as resource focused applications can be within the reach of a number of Small and Medium Sized Businesses, Educational and Research organizations.
