Cloud computing is caused by adoption and the development of existing technologies and paradigms. The aim of cloud computing would be to enable users to choose bene?t from each of these technologies, without expertise with
each one of them or the need for profound knowledge about. With operating system–level virtualization basically creating a scalable system of multiple computing devices that were separate, idle computing resources used and can be allocated better. Virtualization reduces price by improving infrastructure use, and provides the agility needed to speed up IT operations. Autonomic computing automates the procedure whereby resources can be provisioned by the user on demand. By minimizing user participation, automation reduces labour costs, speeds up the procedure and reduces the chance for human errors. Users typically confront tough business issues. Cloud computing embraces theories from Service-oriented Architecture (SOA) that can help an individual break these issues into services that can be incorporated to supply a remedy. Cloud computing makes use of the well, and supplies all its resources as services -recognized standards and best practices obtained in the domain name of SOA allowing simple and world-wide access in a standardized manner to cloud services. Cloud computing additionally leverages concepts to provide metrics for the services. Such metrics have reached the heart of the public cloud pay-per-use models. Cloud computing supplies technologies and the tools to construct information/compute intensive programs that are concurrent with costs that are substantially more affordable when compared with conventional parallel computing techniques.

Grid computing—"A type of distributed and concurrent computing, whereby a 'superb and virtual computer' consists of a bunch of networked, loosely coupled computers acting in concert to perform quite big jobs." Fog computing—Distributed computing paradigm providing you with storage, compute, information and program services closer to close or client -user border devices, including network routers. Also, fog computing manages information at the network level, on smart devices and on the end user client side (e.g. cellular apparatus), instead of sending information to a distant place for processing. Compared to fog computing, which supports emerging IoT programs that require realtime and predictable latency and the network reconfigurability that is dynamic, Dew computing pushes at the frontiers to computing low level services, and programs, information away from focused virtual nodes to the end users. Mainframe computer—Strong computers used primarily by big organizations for essential applications, typically bulk data processing for example: enterprise resource planning; consumer and business numbers; authorities and secret intelligence services; census; and financial transaction processing. Utility computing—The "packaging of computing resources, including computation and storage, as a metered service just like a conventional public utility, like electricity." Peer to peer—A distributed structure with no need for central coordination. Participants are both providers and consumers of resources (in contrast to the conventional client–server model). Green computing Cloud sandbox—A live, remote computer environment where code, a software or file can run without changing the application where it runs.
