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.

Learn: exactly why cloud computing is relevant today from an economic, business and technology standpoint. Hear: first-hand from industry experts what issues and questions you should consider when evaluating cloud-based systems. Cloud-based applications — or software as a service — run on distant computers “in the cloud” that are owned and operated by others and that connect to users’ computers via the internet and, usually, a web browser. Cloud computing is the the use of various services, such as software development platforms, servers, storage and software, over the internet, often referred to as the "cloud.".
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.In cloud computing, elasticity is defined as "the degree to which a system is able to adapt to workload changes by provisioning and de-provisioning resources in an autonomic manner, such that at each point in time the available resources match the current demand as closely as possible".
Elasticity is a defining characteristic that differentiates cloud computing from previously proposed.
Simply put, cloud computing is computing based on the urbanagricultureinitiative.com in the past, people would run applications or programs from software downloaded on a physical computer or server in their building, cloud computing allows people access to the same kinds of applications through the internet.
