Q4
Are my peers really moving to the cloud as fast as the media say they are?
ANSWER: Yes and no. Yes, a good percentage of your peers have at least some applications in the cloud. The benefits of cloud deployment are just too attractive not to make cloudcomputing part of their overall IT strategy. And no, in that many of them are just scratching the surface of cloud utilization and in realizing the true benefits to their business. If you’re looking at your first strategic cloud deployment, you’re probably not that far behind your peers no matter what you read in last week’s tech magazine, which means there’s still time to gain a competitive advantage by moving to
“The biggest impact of the cloud is the ability to accelerate the rate of innovation for the business. The cloud is enabling a tripling in the number of new developers and innovators who can create business value through IT. Together, they are going to create about a tenfold increase in new killer applications.” —Frank Gens, Senior Vice President and Chief Analyst at IDC, The Cloud’s Game Changer Is Competitive Advantage, CIO.com, June 5, 2015

The Time is Now Cloud computing has moved well-beyond the days when the only organizations moving to the cloud were those comfortable living on the “bleeding edge” of technology. That said, cloud technology developers and providers are constantly innovating and introducing new capabilities. There may never come a day when cloud computing technologies feel “mainstream” because as soon as the majority have adopted a technology, it gets replaced by something more innovative. Organizations that want to take advantage of the business benefits cloud computing offers will need to get comfortable with the increasing pace of innovation and to find new ways to leverage technology in their organization. Of course, that doesn’t mean an organization need expose itself to unacceptable levels of risk to take advantage of the cloud. We can help you choose the cloud that best supports your strategy. Just give us a call.
