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. Some analysts and vendors define cloud computing narrowly as an updated version of utility computing: basically virtual servers available over the Internet. Others go very broad, arguing anything you consume outside the firewall is "in the cloud," including conventional outsourcing.

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 encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities.
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. Yes, utility-style infrastructure providers are part of the mix, but so are SaaS (software as a service) providers such as Salesforce.com. Today, for the most part, IT must plug into cloud-based services individually, but cloud computing aggregators and integrators are already emerging.
InfoWorld talked to dozens of vendors, analysts, and IT customers to tease out the various components of cloud computing. Based on those discussions, here's a rough breakdown of what cloud computing is all about:

This type of cloud computing delivers a single application through the browser to thousands of customers using a multitenant architecture. On the customer side, it means no upfront investment in servers or software licensing; on the provider side, with just one app to maintain, costs are low compared to conventional hosting. Salesforce.com is by far the best-known example among enterprise applications, but SaaS is also common for HR apps and has even worked its way up the food chain to ERP, with players such as Workday. And who could have predicted the sudden rise of SaaS "desktop" applications, such as Google Apps and Zoho Office?
2. Utility computing
The idea is not new, but this form of cloud computing is getting new life from Amazon.com, Sun, IBM, and others who now offer storage and virtual servers that IT can access on demand. Early enterprise adopters mainly use utility computing for supplemental, non-mission-critical needs, but one day, they may replace parts of the datacenter. Other providers offer solutions that help IT create virtual datacenters from commodity servers, such as 3Tera's AppLogic and Cohesive Flexible Technologies' Elastic Server on Demand. Liquid Computing's LiquidQ offers similar capabilities, enabling IT to stitch together memory, I/O, storage, and computational capacity as a virtualized resource pool available over the network.Source(s): hi dear get it it is very nice u never this answer please try to understand i worked hard to get answer of ur question so plz cooperate

Cloud computing allows employees to be more flexible in their work practices. For example, you have the ability to access data from home, on holiday, or via the commute to and from work . If you need access to your data while you are off site, you can connect to your virtual office, quickly and easily. Your business can scale up or scale down your operation and storage needs quickly to suit your situation, allowing flexibility as your needs change. Rather than purchasing and installing expensive upgrades yourself, your cloud computer service provider can handle this for you. Using the cloud frees up your time so you can get on with running your business.Source(s): https://tr.im/Lmgiz

The fairly new concept of Cloud Computing has hit the world of business with a ‘BANG’, and is being adopted, not only by Small and Medium sized Businesses but also by Large Enterprises. This is rapid shift towards this emerging technology is due to its ability to cut down IT costs by many folds, and the allowance it gives to enterprises to focus their energies and resources to their core business. In this article, I will attempt to explain, briefly and without the use of a lot of technical terms, what cloud computing is, and how it is helping businesses do what they are created to do.
The ‘CLOUD’ in Cloud Computing
If you have an email account like Hotmail, Gmail or Yahoo-mail etc., then you are already using cloud services being offered to you by your email service provider. The Cloud is a collection of all the servers and IT infrastructure being utilized by your email service provider to manage your email account and store its content. Since you do not have any physical evidence of your email being managed and handled, yet it seems to be happening, we say that it is happening somewhere in the Cloud. The Cloud of servers, functioning in in large datacenters, you may never know where. The benefit of having an email account with these service providers is that it is completely free for you, the user. There is no physical equipment, apart from a laptop, desktop or mobile device that you need to have, along with an internet connection, to access your email.
Adding ‘COMPUTING’ to the Cloud
Like with email providers, Cloud Computing service providers also maintain their own servers and complete IT infrastructures residing at various datacenters through which they are able to offer Cloud Computing solutions to their customers. UNLIKE email providers, however, Cloud Computing service providers rent out not just email capabilities, but entire virtual desktops and servers, software, data storage capabilities, data security, disaster recovery and management solutions and a whole bunch of other stuff, which the user may access from any place, at any time, using any desktop, laptop or mobile device, along with an internet connection.
Cloud Computing Possibilities
Imagine being able to access your own desktop, and all the data stored thereon, while sitting at a train station or an airport. Imagine hundreds of your employees having access to their own personalized desktops and all the information that they require, from anywhere, without actually ever owning a single physical machine. Imagine giving access to software to all your employees, without ever worrying about maintain a record of the number of licenses you have available. Imagine utilizing all of these services for a nominal monthly charge, and being able to add or reduce their number as and when required. Imagine being rid of the increasingly high costs of maintaining a complete IT infrastructure, along with skilled IT labor to manage the infrastructure, forever. These are a few of the many possibilities of utilizing Cloud Computing services. Cloud Computing providers host these services on their own IT infrastructure, which is maintained by their team of highly skilled IT professionals and rent them out to you, relieving you of the HUGE IT costs and headaches. In a nutshell, due to the reason mentioned above, it is the opinion of this writer, that Cloud Computing is THE complete IT solution, and the way to the future for any enterprise, regardless of its size, scale and nature of business.
