Security issues and challenges in cloud computing

Cloud computing is a transpiring way of computing in computer science. Cloud computing is a technology that uses a network of remote servers hosted on internet to store, manage and process data on demand and pay as per use. It provides access to shared resources. As cloud computing do not acquire the things physically, it saves managing cost and time for the organizations. Today it is used in both industrial field and academic field. Cloud facilitates its users through virtual resources via internet. There are some security issues while using services over the cloud. As users of cloud save their data in the cloud hence the lack of security in cloud can lose the user's trust. In this paper, we presents a review on the cloud computing concepts as well as security issues within the context of cloud computing. This paper also analyses the key research and challenges that are present in cloud computing.
