Separating Fact From Fiction in Cloud Computing

Grazed from Data Center Journal. Author: Matt Zieg.

The cloud. The name conjures images of an obscuring mist always out of our reach. The reality of cloud computing can seem just as mysterious. Before hurtling into this nebulous IT frontier, it is important to separate hype from reality.

Cloud computing is a powerful and important tool for today’s businesses, but like any tool it must be used properly to realize its true benefit. Responsible businesses and IT departments will take the time to fully understand the risks and benefits associated with the cloud, challenge common assumptions and misperceptions, and make informed decisions that benefit their organizations and their customers.

Already, according to a 2011 survey from Advanced Micro Devices, about 37 percent of companies are using the cloud. And 24 percent of the respondents to a September 2011 Emerson Network Power survey of data center managers, resellers and engineers said they have plans to pursue or implement a cloud-computing strategy over the next 18 months. According to a 2011 report from IDC, worldwide revenue from public IT cloud services exceeded $21.5 billion in 2010 and is projected to reach $72.9 billion in 2015. Forrester Research is even more bullish, estimating the global cloud-computing market to reach $241 billion in 2020, according to an April 2011 report called Sizing the Cloud. Regardless of who is more accurate, clearly the cloud is growing—and it is far more than the empty hype some suggested as recently as a year ago...
