The word cloud was used as a metaphor for the Internet and a standardized cloud-like shape was used to denote a network on telephony schematics. With this simplification, the implication is that the specifics of how the end points of a network are connected are not relevant for the purposes of understanding the diagram.

No one had conceived that before. The example Jim White [the designer of Telescript, X. Yet, the "data center" model where users submitted jobs to operators to run on IBM mainframes was overwhelmingly predominant.

In the s, telecommunications companies, who previously offered primarily dedicated point-to-point data circuits, began offering virtual private network VPN services with comparable quality of service, but at a lower cost.

By switching traffic as they saw fit to balance server use, they could use overall network bandwidth more effectively. Cloud computing extended this boundary to cover all servers as well as the network infrastructure.

As described by Andy Hertzfeld: November Sincecloud computing has come into existence. The OpenStack project intended to help organizations offering cloud-computing services running on standard hardware.

As an open source offering and along with other open-source solutions such as CloudStack, Ganeti and OpenNebula, it has attracted attention by several key communities.

Several studies aim at comparing these open sources offerings based on a set of criteria. On June 7,Oracle announced the Oracle Cloud. The cloud aims to cut costs, and helps the users focus on their core business instead of being impeded by IT obstacles.

Virtualization software separates a physical computing device into one or more "virtual" devices, each of which can be easily used and managed to perform computing tasks. With operating system—level virtualization essentially creating a scalable system of multiple independent computing devices, idle computing resources can be allocated and used more efficiently.

Virtualization provides the agility required to speed up IT operations, and reduces cost by increasing infrastructure utilization.

Autonomic computing automates the process through which the user can provision resources on-demand. By minimizing user involvement, automation speeds up the process, reduces labor costs and reduces the possibility of human errors. Cloud computing adopts concepts from Service-oriented Architecture SOA that can help the user break these problems into services that can be integrated to provide a solution.

Cloud computing provides all of its resources as services, and makes use of the well-established standards and best practices gained in the domain of SOA to allow global and easy access to cloud services in a standardized way. Cloud computing also leverages concepts from utility computing to provide metrics for the services used.

Such metrics are at the core of the public cloud pay-per-use models.

In addition, measured services are an essential part of the feedback loop in autonomic computing, allowing services to scale on-demand and to perform automatic failure recovery. Cloud computing is a kind of grid computing ; it has evolved by addressing the QoS quality of service and reliability problems.

Client—server model —Client—server computing refers broadly to any distributed application that distinguishes between service providers servers and service requestors clients. Grid computing —"A form of distributed and parallel computing, whereby a 'super and virtual computer' is composed of a cluster of networked, loosely coupled computers acting in concert to perform very large tasks.

Furthermore, fog computing handles data at the network level, on smart devices and on the end-user client side e. Mainframe computer —Powerful computers used mainly by large organizations for critical applications, typically bulk data processing such as:Cloud Computing are data and applications that are accessible through servers around the world (Clouds), and it can be reached at any time, from..
