...Cloud Computing: A Brief Introduction The origin of the term cloud computing is obscure, but it appears to derive from the practice of using drawings of stylized clouds to denote networks in diagrams of computing and communications systems. The word cloud is used as a metaphor for the Internet, based on the standardized use of a cloud-like shape to denote a network on telephony schematics and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. In the 1990s, 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 much lower cost. By switching traffic to balance utilization as they saw fit, they were able to utilize their overall network bandwidth more effectively. The cloud symbol was used to denote the demarcation point between that which was the responsibility of the provider and that which was the responsibility of the users. Cloud computing extends this boundary to cover servers as well as the network infrastructure.[10] The underlying concept of cloud computing dates back to the 1950s; when large-scale mainframe became available in academia and corporations, accessible via thin clients / terminal computers. Because it was costly to buy a mainframe, it became important to find ways to get the greatest return on the investment in them, allowing multiple users...

...Cloud computing Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user's data, software and computation. There are many types of public cloud computing:[1] Infrastructure as a service (IaaS) Platform as a service (PaaS) Software as a service (SaaS) Storage as a service (STaaS) Security as a service (SECaaS) Data as a service (DaaS) Database as a service (DBaaS) Test environment as a service (TEaaS) Desktop virtualization API as a service (APIaaS) Backend as a service (BaaS) In the business model using software as a service, users are provided access to application software and databases. The cloud providers manage the infrastructure and platforms on which the applications run. SaaS is sometimes referred to as “on-demand software” and is usually priced on a pay-per-use basis. Saas providers generally price applications using a subscription fee. Proponents claim that the SaaS allows a business the potential to reduce IT operational costs by outsourcing hardware and software maintenance and support to the cloud provider. This will enable a business to reallocate IT operations to focus on other IT goals. In addition, the application is hosted centrally, so updates can be released without users...

...Cloud Computing Cloud computing is the delivery of computing as a service rather than a product. Resources like software and information are provided to computers and communication devices as a utility like electricity or water. This cloud computing service is done through a computer network, which is the internet typically. Cloud computing is known as encapsulation by some users since the physical location and configuration of how the resources are shared to the devices is often not revealed to the end user. It is like using the electricity. The end user doesn’t have to know the whereabouts of the physical location where the electricity is produced nor how the components are configured from there to their home. They just use the feature or resource instead. Similar to this cloud computing describes the consumption of IT services through the common most computer network available in the world, the internet. Virtualized resources can be shared remotely with ease-of-access exploiting the facilities provided by the internet. The end user must have a tool or an application (Web Browser) installed on their local computers which provides the platform for the sharing of resources. Providers of cloud computing deliver applications or tools via the internet, which are accessed using web browsers and desktop mobile apps, while the main resources (business software and data) are stored in a server located in a remote location. Screen-sharing technology is used sometimes to provide...

...Description of cloud: A set of pooled computing resources, delivered over the web, powered by software. Cloud computing a form of computing that involves the interaction of several virtualized resources, meaning that many servers are connecting and sharing information that can expand and contract across servers depending on the amount of servers needed to manage the amount of traffic on various sites. Cloud computing is often provided “as a service” over the internet, typically in the form of infrastructure as a service (IaaS), platform as a service (PaaS), or software as a service (SaaS). Maturing virtualization in information technology systems has enabled increased implementations of the cloud computing paradigm, dissolving the need to co-locate user and computing power by providing desired services through the network. The “cloud” in “cloud computing” stems from the interconnectivity of the computers and computer networks that form the internet because, when these relationships are diagramed, the resulting image looks like a cloud. In its simplest terms, cloud computing is a new mode of computing where technology-enabled services are delivered to a set of consumers from a set of providers over the network. The definition is inclusive of compute, storage, network, application and service elements, typically running in large data centers accessed by a variety of mobile and fixed devices. Unlike prior computing systems that were essentially dedicated to individual businesses...

...What is Cloud? The term Cloud refers to a Network or Internet. In other words, we can say that Cloud is something which is present at remote location. Cloud can provide services over network i.e. on public networks or on private networks i.e. WAN, LAN or VPN. Applications such as e-mail, web conferencing, customer relationship management (CRM), all run in cloud. What is Cloud Computing? Cloud Computing refers to manipulating, configuring, and accessing the applications online. It offers online data storage, infrastructure and application. We need not to install a piece of software on our local PC and this is how, the cloud computing overcomes platform dependency issues. Hence, the Cloud Computing is making our business application mobile and collaborative. Cloud Computing Technologies There are certain technologies that are working behind the cloud computing platforms making cloud computing flexible, reliable, usable. These technologies are listed below: * Virtualization * Service-Oriented Architecture (SOA) * Grid Computing * Utility Computing Virtualization Virtualization is a technique which allows to share single physical instance of an application or resource among multiple organizations or tenants(customers). It does so by assigning a logical name to a physical resource and providing a pointer to that physical resource when demanded. The Multitenant architecture offers virtual isolation among the multiple tenants and therefore, the organizations...
