Cloud Computing Research Issues, Challenges, Architecture, Platforms and Applications: A Review Paper

Cloud computing come from the development of parallel computing, distributed computing, grid computing and virtualization technologies. Cloud computing is an emerging model of business computing. In this paper, we explore the concept of cloud architecture and address the characteristics and applications of several popular cloud computing platforms. In this paper, we aim to pinpoint the challenges and issues of cloud computing and we also highlighted the cloud interoperability issue that deserves substantial further research and development. Once migrated to cloud, you do not know where your data is physically stored, what laws and regulations govern the same and most important of all, who has access to it. However, security and privacy issues present a strong barrier for users to adapt into cloud computing systems. In this paper, we investigate several cloud computing system providers about their concerns on security and privacy issues.
