Global spending growth will slow down to 6% in 2009, according to analyst firm Gartner though the firm says this will represent fairly robust growth in a generally poor economic environment.
Gartner projects that worldwide IT spending will total US$3.6 trillion (£2 trillion) in 2009, an increase of 6% over its projected total of $3.4 trillion in 2008. Total worldwide IT spending is expected grow by 8% this year and rose 10% in 2007 from the year before, Gartner reports.
Spending on software (8% projected growth in 2009) and IT services (7% projected growth in 2009) will be the fastest growing services, while . hardware spending is projected to slow to just 4% growth next year, down from 10% spending growth on hardware worldwide in 2007.
Telecom spending, which accounts for more than half of all IT spending worldwide, will grow by a projected 6% and will total nearly $2.1 trillion.
Jim Tully, a vice president and distinguished analyst at Gartner, said that while IT spending growth is projected to be slower in 2009 than in 2007 and 2008, IT spending will still be increasing much more rapidly than many other sectors of the economy.
"In subsequent years we will see reduced growth, but the fundamentals remain strong," he says. "Emerging regions, replacement of obsolete systems and some technology shifts are driving growth."
Gartner expects that spending on telecom services will grow slowly and will account for only 44% of the market in five years' time.
Because continued use of older telecom systems will slow down telecom spending growth, Gartner says they will be a drag on overall IT spending as well. Additionally, Gartner offers a cautious note on software spending growth, as software-as-a-service, service-oriented architecture and open source software are all offering heavy competition to traditional software purchasing models.
