Worldwide end-user spending on public cloud services is forecast to grow 20.4% to total US$675.4 billion in 2024, up from US$561 billion in 2023, according to the latest forecast from Gartner.
This growth is being driven by generative AI (GenAI) and application modernisation.
“The continued growth we expect to see in public cloud spending can be largely attributed to GenAI due to the continued creation of general-purpose foundation models and the ramp up to delivering GenAI-enabled applications at scale,” said Sid Nag, Vice President Analyst at Gartner. “Because of this continued growth, we expect public cloud end-user spending to eclipse the one trillion dollar mark before the end of this decade.”
All segments of the cloud market are expected to see growth in 2024. Infrastructure-as-a-service (IaaS) is forecast to experience the highest end-user spending growth at 25.6%, followed by platform-as-a-service (PaaS) at 20.6% (see Table 1).

| 2023 Spending | 2023Growth (%) | 2024 Spending | 2024Growth (%) | 2025 Spending | 2025Growth (%) | |
| Cloud Application Infrastructure Services (PaaS) | 142,934 | 19.5 | 172,449 | 20.6 | 211,589 | 22.7 |
| Cloud Application Services (SaaS) | 205,998 | 18.1 | 247,203 | 20.0 | 295,083 | 19.4 |

“IaaS continues at a robust growth rate that is reflective of the GenAI revolution that is underway,” said Nag. “The need for infrastructure to undertake AI model training, inferencing and fine tuning has only been growing and will continue to grow exponentially and have a direct effect on IaaS consumption.”
While cloud infrastructure and platform services are driving the highest spending growth, SaaS remains the largest segment of the cloud market in end-user spending. SaaS spending is projected to grow 20% to total US$247.2 billion in 2024.
“SaaS spend is driven by applications being modernised by independent software vendors to run in a SaaS-based consumption model,” said Nag. “Organisations continue to increase their usage of cloud for specific use cases such as AI, Machine Learning, Internet of Things and big data which is driving this SaaS growth.”
In the Middle East and North Africa (MENA) region, end-user spending on public cloud services is forecast to grow 19.8%, to total US$7.3 billion in 2024 (see Table 2).

“Public cloud spending is expected to surge as companies in the MENA region are moving towards becoming fully digitalised corporations. Additionally, Middle Eastern countries are also looking for a common economic goal of becoming technology and data centric. Organisations are using cloud as an enabler of technologies such as AI and business analytics to enhance the capabilities,” said Shailendra Upadhyay, Senior Principal Analyst at Gartner.
