Cloud computing is a smart computing model since it allows for resources to be provisioned rendering on a demand basis, i.e., cloud users can lease resources as they become essential. Cloud Computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the data centers that provide those services. This terminology of computing is estimated to be one of the most transformative technologies in the history of computing. Cloud computing delivers infrastructure, platform, and software as services, which are made available as subscription - based services in a pay - as - you - go model to consumers. By leve raging cloud services, organizations can deploy their software systems over a pool of resources. As this computing technology is a rapidly evolving research area, there is a severe lack of defined standards, tools and methods that can efficiently tackle th e infrastructure and application level intricacies. This paper presents and discusses the comprehensive and structured overview of cloud computing and its requirements by analysing its open source technologies along with its main characteristics and infras tructure technologies. This paper will also motivate several academic and non - academic institutions to develop open - source cloud solutions.
