Cloud computing is an upcoming technology that promises for a very scalable and agile computing. The world is experiencing a major breakthrough in resource pooling at a bigger platform than ever before. Although the adoption of this technology is taking place at considerable rate but we still witness some serious hazards here which are inhibiting the IT sector to take full advantage of such a useful technology. This paper discusses about the biggest hazard in the way of cloud computing which is undoubtedly the security. Security in clouds is a major research area these days. So this paper reviews the security concern with their requirement and best practices in cloud architecture.
