Meanwhile, according to research firm Gartner, overall IT spends, including spending on IT services software, computer hardware, data centre systems and communications technologies, are expected to grow slower at 3.2% in 2019 to $3,816 billion as compared to 4.5% clocked in 2018.

Giving the rationale behind the likely slowdown, Gartner said that dip in global growth rates and cost optimisation pressure on the clients will hurt the IT spends. "An expected global slowdown in economic prosperity, paired with internal pressures to cut spending, is driving organisations to optimise enterprise external spend for business services such as consulting," the report said.
