A new report from IDC shows that the worldwide public cloud services market totalled $233.4 billion in 2019, representing a 26% increase year-over-year. The analyst said that spending had consolidated in 2019 with Amazon Web Services, Microsoft, Salesforce.com, Google, and Oracle making up more than one-third of the worldwide total and growing 35% year-over-year.
Discussing the impact that COVID-19 has had on the shift to cloud computing, Rick Villars, group vice president, Worldwide Research at IDC, said:
“Cloud is expanding far beyond niche e-commerce and online ad-sponsored searches. It underpins all the digital activities that individuals and enterprises depend upon as we navigate and move beyond the pandemic. Enterprises talked about cloud journeys of up to ten years. Now they are looking to complete the shift in less than half that time.”
The figures (U.S.$ billion) for the worldwide public cloud services market, produced by IDC, are as follows:
| Segment | 2019 Revenue | Market Share | 2018 Revenue | Market Share | Year-over-Year Growth |
|---|---|---|---|---|---|
| Infrastructure as a Service (IaaS) | $49.0 | 21.0% | $35.4 | 19.1% | 38.4% |
| Platform as a Service (PaaS) | $35.9 | 15.4% | $25.8 | 14.0% | 38.8% |
| Software as a Service (SaaS) | $148.5 | 63.6% | $123.9 | 66.9% | 19.8% |
| Total | $233.4 | 100% | $185.2 | 100% | 26.0% |
Going forward, IDC believes that the current crisis could further boost SaaS products despite the segment having slowed somewhat in the last few years. It said that looking at IaaS and PaaS combined was also useful because it shows how end customers consume these services when deploying applications on a public cloud. Its research also found that Amazon Web Services and Microsoft have more than half the global revenues in these segments but that competition is still healthy.
