DEFINITION:
INTRODUCTION
 The underlying concept of cloud computing dates back to 1960, when John McCarthy opined that "computation may someday be organized as a public utility"; indeed it shares characteristics with service bureaus that date back to the 1960s.
 The actual term "cloud" borrows from telephony in that telecommunications companies, who until the 1990s primarily offered dedicated point-to-point data circuits, began offering “VIRTUAL PRIVATE NETWORK (VPN)” services with comparable quality of service but at a much lower cost.
 The cloud symbol was used to denote the demarcation point between that which was the responsibility of the provider from that of the user. Cloud computing extends this boundary to cover servers as well as the network infrastructure.
 Cost is claimed to be greatly reduced and capital expenditure is converted to operational expenditure. Device and location independence enable users to access systems using a web browser regardless of their location or what device they are using.
USES
 Helps to use applications without installations.
 Access the personal files at any computer with internet access.
 This technology allows much more efficient computation by centralizing storage, memory, processing and band width.
SURVEY
 Based on a study conducted in June 2009 by version one, 41% of IT senior professionals doesn’t have sound knowledge on cloud computing.
 In September 2009, Aberdeen Group found that 18% reduction in there IT budget and a 16% reduction in data center power costs.
LAYERS
APPLICATIONS
 Cloud application services or "Software as a Service (SaaS)" deliver ‘software’ as a service over the Internet, eliminating the need to install and run the application on the customer's own computers and simplifying maintenance and support.
PLATFORM
 Cloud platform services or "Platform as a Service (PaaS)" deliver a computing platform and/or solution stack as a service, often consuming cloud infrastructure and sustaining cloud applications. It facilitates deployment of applications without the cost and complexity of buying and managing the underlying hardware and software layers.
INFRASTRUCTURE
SERVER
 The servers layer consists of computer hardware and/or computer software products that are specifically designed for the delivery of cloud services, including multi-core processors, cloud-specific operating systems and combined offerings

HYBRID CLOUD & PRIVATE CLOUD
CRITICISM
 Richard Stallman, founder of the Free Software Foundation and creator of the computer operating system GNU, said that cloud computing was simply a trap aimed at forcing more people to buy into locked, proprietary systems that would cost them more and more over time. "It's stupidity. It's worse than stupidity: it's a marketing hype campaign," he told The Guardian. "Somebody is saying this is inevitable – and whenever you hear somebody saying that, it's very likely to be a set of businesses campaigning to make it true." "The interesting thing about cloud computing is that we've redefined cloud computing to include everything that we already do," he said.
 The main drawback behind the concept of Cloud Computing is we can’t completely rely on third party when we are transmitting sensitive data.
ISSUES
LEGAL
 In March 2007, Dell applied to trademark the term "cloud computing" (U.S. Trademark 77,139,082) in the United States. The "Notice of Allowance" the company received in July 2008 was cancelled in August, resulting in a formal rejection of the trademark application less than a week later.
 Since 2007, the number of trademark filings covering cloud computing brands, goods and services has increased at an almost exponential rate. As companies sought to better position themselves for cloud computing branding and marketing efforts, “cloud computing trademark filings increased by 483% between 2008 and 2009.” In 2009, 116 cloud computing trademarks were filed, and trademark analysts predict that over “500 such marks could be filed during 2010.”
SECURITY
 The relative security of cloud computing services is a contentious issue which may be delaying its adoption. Some argue that customer data is more secure when managed internally, while others argue that cloud providers have a strong incentive to maintain trust and as such employ a higher level of security.
CONCLUSION
 Cloud computing is a better way to run your business. Instead of running your apps yourself, they run on a shared data center. When you use any app that runs in the cloud, you just log in, customize it, and start using it. That’s the power of cloud computing.
 Finally, cloud apps don’t eat up your valuable IT resources, so your CFO will love it. This lets you focus on deploying more apps, new projects, and innovation
THE BOTTOM LINE
Cloud computing is a simple idea, but it can have a huge impact on your business.
