State of the Art of Cloud Computing and its Research Issues

Cloud computing is a technology that uses the central remote servers and internet to access or maintain data and applications. It allows service consumers and businesses vendors to use applications without any software installation and access their personal files at any time and by any computer with the help of internet access facility. This technology allows more efficient computing by centralizing memory, processing, storage and bandwidth. Cloud computing technology confronted a new computing epitome in the field of internet with operable resources used as services. This forms a new horizon for business venture and projects by cutting down the entry barriers to a greater extent. The objective of this research contribution is to make spotlights on Strengths, Weakness, Opportunities and Threats (SWAT) analysis and research issues of cloud computing.
