US dominates 2022 public cloud market which eclipsed $500bn in global spend

IaaS and PaaS had the largest growth while hyperscaler giants Microsoft, Amazon and Google continue to control the market

Revenues for main public cloud service and infrastructure markets, operators and vendors jumped 21 per cent to $544bn in 2022.

The biggest growth was seen in infrastructure as a service (IaaS) and platform as a service (PaaS), according to data from Synergy Research Group.

Annual revenue from these services grew 29 per cent to reach more than $195bn, despite some major headwinds from the strengthening US dollar and problems in the Chinese market.

In the other main segments, managed private cloud services, enterprise SaaS and CDN added another $229bn in service revenues, having grown by an average 19 per cent from 2021.

In order to support both these and other digital services, Synergy said public cloud providers spent $120bn on building, leasing and equipping their datacentre infrastructure, which was up 13 per cent from the previous year.

Across the entire public cloud ecosystem, Microsoft, Amazon, Salesforce and Google of course dominated.

Other major players included Adobe, Alibaba, Cisco, Dell, Digital Realty, Huawei, IBM, Inspur, Oracle, SAP and VMware.

The market tracker said that in aggregate these companies accounted for 60 per cent of all public cloud-related revenues.

"While cloud markets are growing strongly in all regions of the world, the US remains a centre of gravity," said Synergy.

"In 2022, the US accounted for 45 per cent of all cloud service revenues and 53 per cent of hyperscale datacentre capacity.

"Across all service and infrastructure markets, the vast majority of leading players are US companies, followed by Chinese companies who account for eight per cent of all 2022 cloud service revenues and 16 per cent of hyperscale datacentre capacity."
