Global revenue generated by public cloud services topped the US$500 billion mark in 2022, according to new data released this week by research firm IDC.
The actual figure was US$545.8 billion, IDC’s research found, a sum that represents a 22.9 per cent increase over the previous year. Foundational cloud services — which IDC defines as infrastructure, platform and system infrastructure software delivered as services — grew even more quickly, rising by 28.8 per cent in year-on-year terms.
This foundational spending, according to IDC, reflects the growing dependence organisations have on data and artificial intelligence (AI) services, distributed computing and app frameworks. Spending on infrastructure-as-a-service (IaaS) and platform-as-a-service (PaaS), in particular, should continue to grow more quickly than the overall public cloud market, which cloud providers have reacted to by deploying increasingly high-performance infrastructure.
“This serves two purposes,” said IDC research vice president Dave McCarthy in the report. “First, it unlocks the next wave of migration for enterprise applications that have previously remained on-premises. Second, it creates the foundation for new AI software that can be quickly deployed at scale. In both cases, these investments are resulting in market growth opportunities."
IDC’s data also show a continuing consolidation in the public cloud market. Although the top five public cloud services providers account for less than half of the marketplace, their revenue grew faster than the market at large, at 27.3 per cent last year.
Microsoft is the largest public cloud provider in the world, according to IDC’s information, accounting for 16.8 per cent of the overall market, followed closely by AWS, at 13.5 per cent. Salesforce, Google and Oracle rounded out the top five.
One of the chief drivers of new public cloud spending will be generative AI, IDC’s researchers said. AI capabilities are likely to be a central consideration for most organisations in the immediate future and the importance of public cloud to any potential AI offering cannot be overstated.
“IDC research shows that most organisations rank their public cloud provider as their most strategic technology partner,” said research director Lara Greden, in the IDC report.
"When it comes to planning for PaaS developer and data services, organisations that haven’t yet begun their journeys in developing AI-enabled applications are beginning to prioritise them. Those that have started to adopt AI are finding themselves well positioned to evaluate further adoption of generative AI capabilities in an intelligent app-strategy."
The single largest area of spending in 2022, according to IDC, was software-as-a-service (SaaS) applications, clocking in at US$246.3 billion in revenue, followed by IaaS at US$115.5 billion.
