Cloud Computing— Latest Buzzword or a Glimpse of the Future? Sponsored by Google, Inc. Executive Summary: The chairman of the Cloud Summit Executive 2008 conference reportedly started the event by joking that he asked 20 people to define cloud computing, and got 22 different answers. The term came into vogue a few years ago and has since generated its share of controversy. Here are some descriptions we found for cloud computing: • Something that will “profoundly change the way people work and companies operate.” ( The Economist ) • “Reliance on the Internet for satisfying the computing needs of the users.” (Wikipedia) • “The next step in the evolution of software-as-a-service (SaaS) technology.” ([email protected]. Carey, Arizona State University’s online business publication) • “Industry-speak for just about anything tangentially related to the Internet.” (Ben Worthen, The Wall Street Journal ) • “We’ve redefined cloud computing to include everything that we already do. I can’t think of anything that isn’t cloud computing with all of these announcements.” (Larry Ellison, Oracle) Clearly, there is a diversity of opinion on what cloud computing is, what it isn’t, and whether it’s a sea change or just another technology fad. Our opinion: Don’t get hung up on definitions. Don’t focus on the jargon of whether something is cloud computing, or software as a service, or the latest buzzword. Instead, focus on the changing IT equation. The world of computing is moving away from the on- premises IT model, where you keep buying servers, PCs and software licenses as your business grows. Cloud computing disrupts the conventional model and opens a new IT path for the small-to- midsize business: “clouds” of computing power, accessed over the Internet, become your server and your data center. Among the clouds: inexpensive applications that users can access on demand from any location and through a variety of devices. Cloud computing—or SaaS, if you prefer—frees up budget for companies hand-cuffed by IT expenses. Instead of purchasing additional software licenses and hardware for new employees and new locations, businesses can simply open new employee accounts with providers of their cloud- based services to expand computing capacity. It ultimately helps CIOs rationalize their legacy systems and get their “arthritic IT” in order. This paper provides a snapshot of what is happening in the arena of cloud computing. What are the benefits? Why are businesses embracing it? What does it mean to a business owner or executive? How does it affect the workplace? What are the payoffs and the pitfalls? Is it really ready for "prime time"? 2 Copyright © CBS Interactive Inc. All rights reserved. February 2009.

The Market Landscape The market for cloud computing applications is just beginning to heat up. Consumer applications, such as tax preparation services, sites to maintain photos and create albums, and social networking sites, have blazed the trail for successful SaaS business applications. As cloud computing matures, users are finding that it's much more than just a way to offload desktop applications to the Internet. Cloud computing enhances the framework companies need to foster greater cooperation and collaboration among their work teams—which As Computing Evolves, So Does its Jargon may include employees at multiple locations as well as Few observers agree on what cloud computing is, except for advisers, suppliers, and partners what the word cloud represents. When geeks draw network outside a company’s firewall. diagrams, they often represent the Internet as a cloud. In addition, cloud computing Cloud computing, many say, is a form of software-as-a-service. opens up innovative ways to use Wikipedia defines software-as-a-service (SaaS) as “a model of rich-media capabilities, such as software deployment where an application is hosted as a integrating video into documents service provided to customers across the Internet.

In the business arena, cloud computing is gaining momentum as companies seek applications that are easier and cheaper to implement, use, and maintain. Providers are introducing a steady stream of cloud- based services for enterprise resource planning (ERP), web conferencing, data backup, and other key applications. Some cloud applications come from established companies, such as Salesforce.com, a leader in customer relationship management applications. These companies use cloud computing as a competitive weapon against old-line companies selling conventional products and services. Intacct, for example, is an on-demand financial management and accounting system. "A really interesting and perhaps counter-intuitive phenomenon is that there is a huge demand for SaaS services from enterprises that are firmly committed to the on-premise model," observed Phil Wainewright, ZDNet's SaaS expert. "Perhaps even more surprising is that IT departments are some of the most avid buyers of SaaS services — and they’re turning to SaaS to help them manage their on-premise infrastructure." Security services, email management and security, Help Desk and service management are among the applications that IT managers are handing over to external SaaS providers, Wainewright noted. Wainewright also points out that SaaS is a made-to-order antidote for shrinking capital budgets during economic downturns. He wrote: "... cash-strapped businesses will find the pay-as-you-go SaaS model highly appealing — especially if it helps deliver operational cost savings at the same time.” A survey by ScanSafe, a SaaS provider of security services, supports this thesis. The survey of 300 IT managers found that 78% of them believe economic uncertainty makes SaaS more attractive.

"At any database or software for the most basic level, it's the computing equivalent of the evolution these applications resident on in electricity a century ago when farms and businesses shut down their computers. their own generators and bought power instead from efficient industrial utilities." With so many people comfortable with personal forms of cloud computing, the migration to using it for business productivity was inevitable. Now that trend is gaining traction.
