CLOUD COMPUTING The Greek myths tell of creatures plucked from the surface of the Earth and enshrined as constellations in the night sky. Something similar is happening today in the world of computing. Data and programs are being swept up from desktop PCs and corporate server rooms and installed in “the compute cloud”. In general, there is a shift in the geography of computation. An emerging computer paradigm where data and services reside in massively scalable data centers in the cloud and can be accessed from any connected devices over the internet. Like other definitions of topics like these, an understanding of the term cloud computing requires an understanding of various other terms which are closely related to this. While there is a lack of precise scientific definitions for many of these terms, general definitions can be given. Cloud computing is an emerging paradigm in the computer industry where the computing is moved to a cloud of computers. It has become one of the buzz word...

In the last few years, Information Technology (IT) has embarked on a new paradigm — cloud computing. Although cloud computing is only a different way to deliver computer resources, rather than a new technology, it has sparked a revolution in the way organizations provide information and service. Originally IT was dominated by mainframe computing . This sturdy configuration eventually gave way to the client-server model. Contemporary IT is increasingly a function of mobile technology, pervasive or ubiquitous computing, and of course, cloud computing. But this revolution, like every revolution, contains components of the past from which it evolved. Thus, to put cloud computing in the proper context, keep in mind that in the DNA of cloud computing is essentially the creation of its predecessor systems. In many ways, this momentous change is a matter of "back to the future" rather than the definitive end of the past. In the brave new world of cloud computing, there is room for i...
