Cloud now accounts for an increasing share of the global IT spend, according to IDC's first quarter 2017 Worldwide Quarterly Cloud IT Infrastructure Tracker.
For the quarter, total worldwide cloud infrastructure revenue was reported at $8 billion, for a 14.9 percent year-over-year gain. From a macro perspective, cloud IT infrastructure spending now represents 39 percent of overall worldwide IT spending, up from 33.9 percent in the first quarter of 2016.
"Overall, the first quarter set a strong beginning of the year for the cloud IT infrastructure market," Natalya Yezhkova, research director for Enterprise Storage at IDC, said in a statement. "With positive dynamics in purchasing activity by hyperscalers across all technology segments, we expect a strong year ahead for the fastest growing public cloud segment."
"And as end users continue to embrace the benefits of private cloud infrastructures, spending in this segment will also expand," Yezhkova continued.
The growth of cloud revenue is coming at different rates, depending on the infrastructure segment. Infrastructure sales to enable private cloud deployments in the first quarter of 2017 were reported $3.1 billion in revenue, for a 6.0 percent year-over-year gain.
Public cloud infrastructure revenues in contrast is growing significantly faster, with first quarter revenue of $4.8 billion, for a 21.7 percent improvement over the first quarter of 2016.
