“Cloud computing”, a relatively recent buzzword in IT industry that came into existence after decades of research in virtualization, utility computing, distributed computing, networking, and software services. A cloud introduces an IT environment which is invented for the motive of remotely provisioning measured and scalable resources. It has evolved as a new paradigm for exchanging information and services over the internet. It provides services to the users with greater reliability, flexibility, and scalability. It is used as service-oriented architecture which reduces information related overhead for End-Users. In this paper, we will discuss cloud computing concepts, architecture and we mainly focus on some of the challenges related to the cloud storage.
