How Cloud Computing Works

Let’s say you’re an executive at a large corporation. Your particular responsibilities include making sure that all of your employees have the right hardware and software they need to do their jobs. Buying computers for everyone isn’t enough — you also have to purchase software or software licenses to give employees the tools they require. Whenever you have a new hire, you have to buy more software or make sure your current software license allows another user. It’s so stressful that you find it difficult to go to sleep on your huge pile of money every night.

Soon, there may be an alternative for executives like you. Instead of installing a suite of software for each computer, you’d only have to load one application. That application would allow workers to log into a Web-based service which hosts all the programs the user would need for his or her job. Remote machines owned by another company would run everything from e-mail to word processing to complex data analysis programs. It’s called cloud computing, and it could change the entire computer industry.

In a cloud computing system, there’s a significant workload shift. Local computers no longer have to do all the heavy lifting when it comes to running applications. The network of computers that make up the cloud handles them instead. Hardware and software demands on the user’s side decrease. The only thing the user’s computer needs to be able to run is the cloud computing system’s interface software, which can be as simple as a Web browser, and the cloud’s network takes care of the rest.

There’s a good chance you’ve already used some form of cloud computing. If you have an e-mail account with a Web-based e-mail service like Hotmail, Yahoo! Mail or Gmail, then you’ve had some experience with cloud computing. Instead of running an e-mail program on your computer, you log in to a Web e-mail account remotely. The software and storage for your account doesn’t exist on your computer — it’s on the service’s computer cloud.

Cloud Computing: What Is It?

Cloud computing is no longer just hype or a buzzword for the times. It is reshaping the IT marketplace as we know it, and it's here to stay.
The media love stories about the cloud. "The cloud" and "cloud computing" have become ubiquitous in business and technology news stories. It's popping up in consumer ads and quickly making its way into the high-level discussions of policymakers all over the world.

Early cloud adopters in both the private and public sectors are yesterday's news story. They have paved the way for the rapidly expanding early majority. And to that end, IDC industry analysts expect that worldwide IT spending on cloud services will reach $42 billion next year - in large part because the cloud computing model "offers a much cheaper way for businesses to acquire and use IT." And these days, who isn't cost cutting?

So, if cloud computing is such a big deal, why does the concept itself still leave many scratching their heads? What is cloud computing, exactly?

Well, the term has been used many ways lately. According to the Business Software Alliance, "The key features of the cloud are the ability to scale and provide, as needed, data storage and computing power dynamically in a cost efficient way, without the user having to manage the underlying complexity of the technology. Cloud computing offers tremendous potential for efficiency, cost savings and innovations to government, businesses and individuals alike. These benefits will improve government services and citizen access; transform businesses; provide new innovations to consumers; improve important services such as health care and government-provided services; and create energy savings."

As the new decade unfolds, we can expect to see more businesses, consumers - and even lawmakers - rushing to educate themselves about cloud technology and the implications that it holds for the way they work, live and play. And, they will be asking lots of questions. How will it alter the landscape of traditional IT offerings? How will it drive down costs? How will it dovetail with traditional IT architecture? Will it give rise to new policy debates?

BSA, the voice of the world's software industry on a range of business and policy affairs (and for whom I once worked), has produced a solid educational video "to help speed this transition, especially for policy-makers." The video provides the fundamentals of cloud computing - including what defines it and how it is being used, touches on its many benefits (increased efficiencies, scalability, enhanced functionality, cost savings, etc.), and then outlines key policy considerations for lawmakers.

If you are already familiar with the news coverage around cloud computing trends, you might wonder if cloud computing has the potential to usurp existing server, desktop and mobile technologies altogether. BSA's video explains why the cloud model will instead "complement more-established IT architecture." The video describes public, private and hybrid cloud-based implementations and responds to a wide range of policy questions on privacy and security, technology standards, intellectual property and more.

What is Cloud computing


Cloud Computing Training in Jaipur
A cloud refers to a distinct IT environment that is designed for the purpose of remotely provisioning scalable and measured IT resources. The term originated as a metaphor for the Internet which is, in essence, a network of networks providing remote access to a set of decentralized IT resources. Prior to cloud computing becoming its own formalized IT industry segment, the symbol of a cloud was commonly used to represent the Internet in a variety of specifications and mainstream documentation of Web-based architectures. This same symbol is now used to specifically represent the boundary of a cloud environment, as shown in

It is important to distinguish the term "cloud" and the cloud symbol from the Internet. As a specific environment used to remotely provision IT resources, a cloud has a finite boundary. There are many individual clouds that are accessible via the Internet.

Whereas the Internet provides open access to many Web-based IT resources, a cloud is typically privately owned and offers access to IT resources that is metered.

Much of the Internet is dedicated to the access of content-based IT resources published via the World Wide Web. IT resources provided by cloud environments, on the other hand, are dedicated to supplying back-end processing capabilities and user-based access to these capabilities. Another key distinction is that it is not necessary for clouds to be Web-based even if they are commonly based on Internet protocols and technologies. Protocols refer to standards and methods that allow computers to communicate with each other in a pre-defined and structured manner. A cloud can be based on the use of any protocols that allow for the remote access to its IT resources.
