What cloud computing really means

What cloud computing really means
Cloud computing is all the rage. "It's become the phrase du jour," says Gartner senior analyst Ben Pring, echoing many of his peers. The problem is that (as with Web 2.0) everyone seems to have a different definition. As a metaphor for the Internet, "the cloud" is a familiar cliché, but when combined with "computing," the meaning gets bigger and fuzzier. [ Stay on top of the state of the cloud with InfoWorld's "Cloud Computing Deep Dive" special report. Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing is at an early stage, with a motley crew of providers large and small delivering a slew of cloud-based services, from full-blown applications to storage services to spam filtering. 1. 2.

CloudApps - Align. Engage. Sustain. Cloud computing for business goes mainstream 6 May 2010Last updated at 00:04 By Tim Weber Business editor, BBC News website Investing in the cloud means less capital expenditure. Cloud computing has been an information technology buzzword for many years. Now it is going mainstream. Bryan Kinsella has a problem. Email is a key management tool but as the company grew it found itself with 40 different email systems across 50 countries for 20,000 employees, with another 15,000 staff offline. Setting up a new single email system with a global server infrastructure would have meant a massive capital expenditure. Instead, he settled on a "cloud" solution, rolling out Google's enterprise email across the company. The Cloud explained But what is cloud computing? Cloud fans claim five key benefits: Cheap: your IT provider will host services for multiple companies; sharing complex infrastructure is cost-efficient and you pay only for what you actually use. Bear in mind, cloud computing is not new. Using the cloud Competition boosts cloud computing

Cloud computing Cloud computing metaphor: For a user, the network elements representing the provider-rendered services are invisible, as if obscured by a cloud. Cloud computing is a computing term or metaphor that evolved in the late 1990s, based on utility and consumption of computer resources. Cloud computing involves application systems which are executed within the cloud and operated through internet enabled devices. Purely cloud computing does not rely on the use of cloud storage as it will be removed upon users download action. Clouds can be classified as public, private and hybrid.[1][2] Overview[edit] Cloud computing[3] relies on sharing of resources to achieve coherence and economies of scale, similar to a utility (like the electricity grid) over a network.[2] At the foundation of cloud computing is the broader concept of converged infrastructure and shared services. Cloud computing, or in simpler shorthand just "the cloud", also focuses on maximizing the effectiveness of the shared resources.

Virtualization Virtualization, in computing, refers to the act of creating a virtual (rather than actual) version of something, including but not limited to a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization began in 1960s mainframe computers as a method of logically dividing the system resources provided by mainframes between different applications. Since then, the meaning of the term has broadened.[1] Hardware virtualization[edit] Hardware virtualization or platform virtualization refers to the creation of a virtual machine that acts like a real computer with an operating system. In hardware virtualization, the host machine is the actual machine on which the virtualization takes place, and the guest machine is the virtual machine. Different types of hardware virtualization include: Hardware-assisted virtualization is a way of improving overall efficiency of virtualization.

VoIP on Web2.0 Programming Languages - Strengths and Weaknesses Since the 1950s, computer scientists have devised thousands of programming languages. Many are obscure, perhaps created for a Ph.D. thesis and never heard of since. Others became popular for a while then faded due to lack of support or because they were limited to a particular computer system. Read more about What is a programming language? Comparing Programming Languages There are several ways to compare computer Languages but for simplicity we'll compare then by Compilation Method and Abstraction Level. Compiling to Machine Code Some languages require programs to be transformed directly into Machine Code- the instructions that a CPU understands directly. Interpreted Languages Other languages are either Interpreted such as Basic, Actionscript and Javascript, or a mixture of both being compiled to an intermediate language - this includes Java and C#. An Interpreted language is processed at runtime. Level of Abstraction The other way to compare languages is level of abstraction.
