Cloud computing is a field of IT that can revolutionize the traditional computing facilities. Cloud Computing gives a new view to the authors' hardware and software facilities by making them elastic rather than scalable. The system can be scaled up or down according to a user's need. The use of open source technology is a turning point in providing cloud computing infrastructure to reduce the cost by a large magnitude. They can build their own private clouds and share resources viz. hardware and software without making any investment.
