Research firm Gartner Inc. expects worldwide enterprise IT spending to total $2.7 trillion in 2012, a 3.9% increase from 2011 spending of $2.6 trillion. While the cloud still accounts for a relatively small percentage of spending on IT, investments in cloud services will grow sharply in the coming years, the firm says.

Gartner provided its latest outlook for the IT industry on Oct. 17 to an audience of 8,500 CIOs and IT leaders at Gartner Symposium/ITxpo.

The cloud combines the industrialization of IT capabilities and the disruptive impact of new IT-led business models, Gartner says. The shift away from traditional IT acquisition models to public cloud services is still in the very early stages, the firm notes. For example, it estimates that while $74 billion was spent on public cloud services in 2010, only represented 3% of enterprise spending.

Public cloud services will grow five times faster than overall IT enterprise spending (19% annually through 2015), Gartner predicts.

“What supply chain models did to manufacturing is what cloud computing is doing to in-house data centers,” Peter Sondergaard, senior vice president at Gartner and global head of research, said in a statement. “It is allowing people to optimize around where they have differentiated capabilities.”

Trends such as the cloud, social media, mobility and the explosion in information are innovative and disruptive just on their own, but brought together they are revolutionizing business and society, Sondergaard said. “This nexus defines the next age of computing,” he said. “To understand this change, you must appreciate each of the forces.”
