A Cloud Computing Survey with its Applications and Challenges?

Cloud computing is an emerging technology in the computer industry where the computing is moved to a cloud of computers. This emerging technology opens new era of e-services in different disciplines. Cloud computing is the style of computing where massively scaled IT related capabilities are provided as a service across the internet to multiple external customers and are billed by consumption. Cloud computing also provides power referenced with Multimedia-IT as a service. Users can enjoy the service even he knows nothing about the technology of cloud computing and the professional knowledge in this field and the power to control it. In this paper, we give the characteristics of cloud computing and also data storage security issues in it. We explore cloud computing services and applications used mainly in India along with its design challenges.
