Software as a service, which allows organizations to access software over the Web instead of locally on a desktop, is rapidly pervading the enterprise space, with nearly 73 percent of large companies saying they have adopted it or plan to adopt it in the next 18 months, according to a recent survey by Kelton Research.
The participation by general business people in the survey, rather than only technology executives, shows just how disruptive an innovation SaaS has been for IT: if a line-of-business department doesn't want to wait for IT to provide them with a piece of technology, as the saying now goes, a SaaS offering is only "a credit card purchase away."
