Abstract: - Cloud computing is a new technology and rapid development area, most of the research scholar selected cloud computing area to continue his research and its support for data mining, networking, mobile computing, big data analysis. This paper deals with introduction of cloud computing, types, service model, task, data storage, security, challenges and its applications. Key words: Cloud, task. Data storage, Security. 1. Introduction Cloud computing is a variable technology that can support a broad spectrum of application. The term cloud refers to a network and internet. Cloud is present at remote location cloud provide service over network. The cloud computing refers to the many different type of and application being delivered in the internet cloud and the fact that many cases, the devices used to over the service and application. Cloud computing not application oriented but service oriented .There gives the following three sensitive states that are particular concern with in the operational context of cloud computing  The transection of personal sensitive data to the cloud server  The transmission of data from cloud server to client  The Stage of client personal data in cloud server which are remote server not owned by the clients
