New Delhi: Global IT spending is expected to grow 4.5% to $3.68 trillion this year, research firm Gartner said on Tuesday. At about $3.52 trillion currently, it is expected to grow further by 2.7% next year to touch $3.78 trillion.

“Global IT spending growth began to turn around in 2017, with continued growth expected over the next few years," Gartner Research vice-president John-David Lovelock said.

He cautioned, however, that uncertainty looms as organisations consider the potential impacts of Brexit, currency fluctuations and a possible global recession. “Despite this uncertainty, businesses will continue to invest in IT as they anticipate revenue growth, but their spending patterns will shift," he noted.

Projects in digital business, blockchain, Internet of Things (IoT), and progression from big data to algorithms to machine learning to artificial intelligence (AI) will continue to be main drivers of growth, Lovelock added.

Enterprise software is expected to continue growing at a strong pace at 9.5% in 2018, and another 8.4% in 2019 to total $421 billion at the end of two years. The devices segment is expected to grow 5.6% in 2018 to $704 billion, while data centre systems is forecast to expand to $179 billion, Gartner said.
