Cloud computing - a review on benefits, challenges and applications

Abstract

In this paper the applications, benefits and challenges of cloud computing are reviewed. Firstly in 1960s the main concept of cloud computing was given by Professor John McCarthy from Stanford University. He stated that computation and computer’s applications will become public utilities. Nowadays, the users can use resources and applications with cloud through Internet. Cloud computing has many superior aspects such as costs, elasticity, resource pooling, self-service information technology infrastructure, service can be measured. Nevertheless there are still some barriers that prevent the development of cloud computing such as availability of service, data lock in, data transfer bottlenecks, reputation fate sharing, software licenses and security. The top security threats of clouds are also mentioned in this paper.
