But there are also some businesses that are adopting cloud services and regretting it. Nucleus Research found in a survey that 52% of cloud CRM customers were willing to consider switching vendors within six months. "What we saw was that companies had often been sold aggressively and they spent less time on due diligence and planning," says Rebecca Wettemann, an analyst at Nucleus, which offers IT research and advisory services.
The cloud doesn't fit all use cases. "It's not a silver bullet. It's not the right answer for every situation," says Casey Coleman, chief information officer for the General Services Administration.
Only fools rush in
As the first federal government agency to deploy a cloud-based email service agency-wide, the GSA didn't have a road map to follow, says Coleman. So beginning in May 2009 it thoroughly examined its current costs as well as projections for the cloud service.
"It is the case that it has to be well thought out and methodical. This is an IT project like any other. You have to plan for change management, promote user awareness, ensure cyber security in contractual terms, like with any IT project. If you don't approach it in that manner, you might have a different experience," Coleman says. "The promise of cloud computing has been borne out in our experience."

When the GSA adopted Google Apps for email in July 2011, it was able to realize added cost savings by also transitioning non-email systems that were attached to its legacy email system. The agency had been using Lotus Notes for email, plus Domino for workflow apps. As part of its review of adopting Apps for email, the GSA took a hard look at the Domino apps. "We ended up reviewing those apps and eliminating most of them," she says.
The GSA had 2,000 apps in Domino, ranging from small databases to more substantial workflows. It got rid of all but 500 of those apps, with many consolidated and reworked in Force.com. Cutting so many apps meant that the GSA could then turn off 300 in-house servers, Coleman says.
Those savings plus others meant the GSA projected that it would save $16 million over five years by moving to Google Apps for email -- and to date that estimate is proving to be accurate, Coleman says.
