With the advent of Internet technology, cloud computing has become backbone for IT enabled serviceswith tremendous momentum. It is a growing paradigm which offers on-demand services on a pay-per-use basis. Now a days the need for online services such as storage space, software, platforms etc. is increasing rapidly. Cloud computing is a model for enabling on-demand, on-network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services). Due to its virtualization technique, location independency, scalability cloud has revolutionized IT and business regime in today’s era. This paper aims to provide basic understanding of cloud, the technological innovation regarding this field, its service and architecture in a brief and lucid manner. In addition to that the advantages,  different security issues and challenges in cloud computing have been highlighted in this paper.
