What exactly is cloud computing and why is it important for you to know about it? Hearing the term "cloud computing" for the first time around would bring a plethora of things to mind. So before you pack your mountain gear and climb Mt. Everest to surf the net amidst the clouds, it might be a good idea to first read through some overview on what cloud computing is and after three minutes, you would have a fair notion of what the buzz is all about.
For starters, the cloud in the term refers to Internet as a system. Have you ever seen drawings of groups of computers connected to the information superhighway? Then you must have surely noticed that the symbol used for Internet is a cloud. Since the birth of the World Wide Web, a lot of geeks and gurus have toyed with the idea of using Internet as a global platform, a kind of a scalable system that delivers web based applications your business need without worrying about the kind of IT infrastructure you have.
Business applications have always looked appealing to the business sector, particularly the small to medium enterprise, who would also like to use available business applications to run their businesses. However, while it is true that these myriad of business applications do help in managing the day to day operations of the business, it is downright expensive and sometimes requires you to upgrade your existing IT infrastructure. These business applications also needs a data center for it to run smoothly, a stable power, reliable network, cooling systems, storage, a host of third party applications for it to survive, and to top it all, an IT team to monitor and supervise everything. Whew! That's quite a lot, right? This is why a lot of small and medium enterprises would rather play it conservatively and let everything stay as they are.
But wait! The dawn may be breaking for these businesses because it is now becoming apparent that cloud computing is coming their way. Cloud computing makes it possible for small businesses to make use of the best business software available on a shared data center. Where before you need complex hardware, software, and a team of experts to run your data center, all you would need now is just your computer, an Internet connection, and you can choose from among the horde of web based business applications on the data center! Think of cloud computing akin to your utility provider, you just plug the cable in, and you're good to go! Fast, easy, reliable, and the best part is that it costs way below than having your own data center.
Isn't this the most enlightening three minutes you have ever spent? Now, you can definitely hold your head up high and tell your friends about cloud computing.

Cloud Computing - Economics, Service Model & Challenges
Customer Information is the ultimate form of delivery of computing resources. It runs the convention established in the Internet where clients and servers to interact at a distance and demand. In fact, the work and the revenue model is so similar that can be called "The Internet as a product."
Cloud computing offers services ranging from data storage from end to end computing. You can run SAP application or any relatives, file sharing, video store, run or e-mail clients use the platform to collaborate in real time from anywhere in the world through even the most basic computing devices.
Cloud computing takes the task of infrastructure deployment and makes the technology, software platform or commodity only available as electricity. You pay according to use, and create other costs that when combined, are much less than conventional forms of technology acquisition.
Economics of Cloud Computing
To be free to demand a solution, (cloudcomputing) has the innate ability to adapt to user needs. Following the recession of 2007-2009, when cost reduction became an important part of best business practices, cloud computing offers a new economic model for companies to exploit.
According to IDC's analysis, forecasts for 2013 amounts to 44.2 billion U.S. dollars. The reason for such a new economic order is the flexibility and cost effectiveness offered by cloud computing. Massive investments are being made to concentrate on hardware and architecture is being upgraded to offer global capabilities.
Cloud Computing Service Model
The real attraction of cloud computing is its versatility and adaptability. You can categorize the service provided by cloud computing in three classes:
Software as a Service (SaaS): A software, available upon request and provided by a third party provider, configurable remotely via the Internet. Best examples are the tools of online spreadsheet, processing and delivery of web content services of the word (SalesforceCRM, Google Docs, etc.) and CRM services.
Platform as a Service (PaaS): Allows customers to use the platform to develop new applications using the API, which can be deployed and configured remotely. The platform provides development tools and configuration management. Examples are Microsoft Azure PaaS, strength, and Google App Engine.
Infrastructure as a Service (AAI): This provides hardware abstraction, virtual machines and operating systems, which are controllable through an API service. Examples AAI is AmazonEC2 and S3, Terremark Enterprise Cloud, Windows Live Skydrive and Rackspace Cloud.
Challenges
As cloud computing is a centralized form of the transaction, the clouds can be easily tracked and attacked. Moreover, as access remains global intrusion control becomes a challenge as well. Although the deployment of safe practices at the ends of the client can check the intrusion, the crowd makes the biggest task.
Another major challenge is the easy access platforms for cloud computing to user data. Moreover, many public cloud computing platforms are not open to audit of its security measures.
Cloud Computing Security Measures
With the danger of attack on the central configurations of clouds, cloud computing providers have responded with a security practice that includes:
* Risk assessment
* Defense in Depth
* Reassessment of cyclical risks
* Innovative Countermeasures
Companies like Microsoft have their cloud systems reviewed and audited for safety. Other practices, such as business continuity and data recovery have been launched for the worst case in which failure or technical problems may hamper the work process or destroy data. The companies now working on cloud computing security are Novell, Ping Identity, TriCipher and Symplified.
