A Revolution in Information Technology - Cloud Computing

What is the Internet? It is collection of “interconnected networks” represented as a Cloud in network diagrams and Cloud Computing is a metaphor for certain parts of the Internet. The IT enterprises and individuals are searching for a way to reduce the cost of computation, storage and communication. Cloud Computing is an Internet-based technology providing “On-Demand” solutions for addressing these scenarios that should be flexible enough for adaptation and responsive to requirements. The huge amount of information that resides in the Cloud for servicing various enterprises and for making enterprises secure sensitive data should reside in corporate data centers whereas the rest can reside in public data centers. The Cloud manages upgrades and provides information backup in the event of a disaster and/or a system crash. The capital and operational costs of running data centers are reduced by Cloud Computing making IT enterprises focus on strategic projects. In this paper, Cloud Computing is discussed and the various aspects of Cloud Computing outlined such as advantages, limitations, problems and solutions, applications with E-governance, emerging and future trends.
