CLOUD COMPUTING: STATE-OF-THE-ART AND RESEARCH CHALLENGES

Abstract

Cloud computing in recent times emerged as a latest standard for hosting and delivering services over the Internet. Cloud computing is eye-catching to big business owners as it eliminates the necessity for users to plan in advance for provisioning, and allows enterprises to establish from the initial stage and increase resources only when there is a grow in service demand. On the other hand, in spite of the reality that cloud computing offers very huge opportunities to the IT industry, the growth in cloud computing technology is presently at its early years, with many research issues still to be addressed. In this paper, we present cloud computing, highlighting its key concepts, architectural principles, and research challenges. The aim of this paper is to present a better understanding of the design challenges of cloud computing and recognize essential research directions in this increasingly significant area.
