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.

The term Cloud Computing derives from the common depiction in most technology architecture diagrams, of the Internet or IP availability, using an illustration of a cloud. The computing resources being accessed are typically owned and operated by a third-party provider on a consolidated basis in Data Center locations. Target consumers are not concerned with the underlying technologies used to achieve the increase in server capability, and is sold simply as a service available on demand. Grid computing is a technology approach to managing a cloud. In effect, all clouds are managed by a grid but not all grids manage a cloud. More specifically, a compute grid and a cloud are synonymous, while a data grid and a cloud can be different.
Cloud computing gained attention in 2007 as it became a popular solution to the problem of horizontal scalability.
A computer cluster can offer cost-effective service in specific applications, but may be limited to a single type of computing node that allows all nodes to run a common operating system. Alternatively, the canonical definition of grid is one that allows any type of processing engine to enter or leave the system dynamically. This is analogous to an electrical power grid on which any given generating plant might be active or inactive at any given time.
Critical to the notion of cloud computing is the automation of many management tasks. If the system requires human intervention to allocate processes to resources, it's not a cloud, but is merely a data center.

Cloud computing also known as virtual server computing, the model computing technologies using computer and network development based on internet. The term “cloud” here is a metaphor for networking parlance Internet and as an associate of the complexity of the infrastructure contained in it. In this computing model, all possibilities related to information technology are provided in the form of “service”, allowing users to access technology services from a provider that “in cloud” without having to have the knowledge and experience of the technology, and not care about the infrastructure that serves the technology. -

Most small businesses have a server in their office with a series of desktop computers
networked to the server. That hardware layer is typically referred to as "the network," or "the
information systems." With cloud computing, imagine that you no longer have the server in your
office. Instead it is out there somewhere else on the Internet, or in other words it is "in the cloud."

Cloud computing promises better infrastructure and services that allow you to expand your business and reduce cost at the same time.Implementing new IT solutions usually means buying more software, more servers, and spending more money. As a business grows in size and complexity, it requires increasingly sophisticated technology to run effectively.Source(s): http://www.janbask.com/cloud-computing/

It's where a bunch of computers on the internet work together to store and process your information, and then it gets stolen :(
