RE: 2026 – Mid Year 

Cloud infrastructure has become a central operating layer of the internet economy. Its original value was remote capacity: companies rented computing power and storage from outside facilities rather than owning the full server stack themselves. That function remains central, but the industry is moving beyond remote hosting. Cloud infrastructure now provides the environment where data is processed, secured, analyzed, and acted on by increasingly automated systems.

Artificial intelligence is changing the role of cloud infrastructure. In the earlier cloud era, the main service was access to software and data hosted somewhere else. In the AI era, cloud platforms are becoming distributed processing environments that connect data inputs with models and automated workflows. The cloud is no longer only a remote location for computing. It is becoming a control layer for machine-driven digital activity.

Automated activity already represents a large share of internet use. Bad bots alone account for more than one-third of all internet traffic, and non-human traffic has approached half of measured web activity in recent industry reporting. AI adds another layer to this shift because models collect inputs, trigger actions, generate outputs, and interact with cloud-hosted systems at machine speed. Cloud infrastructure is therefore becoming a nervous system for the internet economy, not simply a warehouse for remote computing.

The industry reached a new scale in 2025. Global cloud infrastructure services revenue rose to about $419 billion, and broader public cloud spending was forecast at about $723.4 billion. IaaS accounted for about $211.9 billion of that total, while PaaS accounted for about $208.6 billion. Cloud infrastructure now carries institutional weight as a digital infrastructure sector with software economics and physical constraints.

Key takeaway: Cloud infrastructure reached about $419 billion in 2025 and is now a core digital infrastructure industry.

New Trends

AI is the clearest new force reshaping cloud infrastructure. AI workloads require denser computing environments and more specialized hardware than many earlier cloud workloads. Provider revenue, cloud backlog, data-center construction, and electricity forecasts all show the same direction. Google Cloud ended 2025 with an annualized revenue run rate above $70 billion and a backlog of about $240 billion. Oracle’s cloud infrastructure revenue grew 93% year over year in the fourth quarter of fiscal 2026.

Cloud marketplaces are also becoming a more important part of the industry’s structure. Hyperscaler marketplace sales reached about $30 billion in 2024 and are forecast to reach about $163 billion by 2030. That growth shows that cloud platforms are becoming procurement systems as well as computing systems. Enterprises are not only renting infrastructure from cloud providers; they are increasingly buying software and digital services through the same institutional channels.

Key takeaway: Cloud marketplaces are projected to grow from about $30 billion in 2024 to about $163 billion by 2030.

Milestones

Cloud infrastructure crossed several scale thresholds in 2025. The industry became a $400 billion-plus annual market. AWS reached about $128.7 billion in annual net sales. Azure surpassed $75 billion in annual revenue. Google Cloud ended the year with an annualized revenue run rate above $70 billion. The largest cloud businesses now operate at the scale of major global infrastructure providers.

The physical footprint of the industry also reached a new stage. AWS operated 39 regions and 123 availability zones. Microsoft operated more than 400 data centers across more than 70 regions. Oracle operated more than 50 public cloud regions. Google Cloud served more than 200 countries and territories. These figures show that the cloud industry is now defined by capital-heavy infrastructure as much as by software demand.

Key takeaway: The largest cloud providers now operate with infrastructure scale comparable to major global utilities and network operators.

Outlook

Cloud infrastructure is likely to keep growing, but the industry is moving into a more capacity-constrained phase. Spending forecasts remain strong, provider revenues continue to rise, and AI workloads are increasing demand for computing capacity. Growth now depends more heavily on data-center construction, energy availability, specialized chips, and network buildout than it did during earlier phases of cloud adoption.

The near-term picture is shaped by continued IaaS and PaaS growth, rising hyperscaler revenue, expanding cloud marketplaces, and higher AI infrastructure demand. The longer-term picture is more constrained. Power availability, data-center siting, water use, cybersecurity risk, switching costs, cloud cost management, and market concentration will influence how quickly cloud infrastructure can continue expanding.

Key takeaway: Cloud growth remains strong, but the industry’s limiting factors are shifting from software adoption to physical capacity.

Supplemental Data

Ecological Impact

The ecological impact of cloud infrastructure is becoming more visible as AI increases demand for data-center capacity. Data centers consumed about 415 TWh of electricity globally in 2024, equal to roughly 1.5% of global electricity use. By 2030, data-center electricity consumption is projected to reach about 945 TWh, or just under 3% of global electricity use.

The cloud industry’s environmental footprint is not only a question of electricity volume. Data centers require stable power supply, cooling systems, land, grid connections, and local permitting. AI workloads increase the pressure because accelerated computing systems can require higher power density than traditional enterprise computing. The environmental question is therefore part of the industry’s operating model, not a separate external issue.

Key takeaway: Data-center electricity use is projected to rise from about 415 TWh in 2024 to about 945 TWh by 2030.

Global Specifics

Cloud infrastructure is one of the most concentrated global technology markets. Amazon, Microsoft, and Google together held about 63% of global enterprise cloud infrastructure spending in 2025. Amazon’s estimated share was about 28%, compared with about 21% for Microsoft and about 14% for Google.

Adoption is broad but uneven. In the European Union, 52.74% of enterprises purchased paid cloud computing services in 2025. Adoption reached 84.67% among large enterprises, compared with 49.3% among small enterprises. The gap shows that advanced cloud usage still depends heavily on institutional capacity.

Cloud workload scale also shows how much digital activity now runs through rented infrastructure. AWS S3 stores more than 500 trillion objects and handles more than 200 million requests per second on average. AWS Lambda processes more than 15 trillion requests per month. These figures do not represent total global cloud transactions, but they show the machine-scale activity now operating through cloud systems.

Key takeaway: Amazon, Microsoft, and Google held about 63% of global enterprise cloud infrastructure spending in 2025.

Regional Specifics

The United States remains the largest country contributor to cloud infrastructure demand and data-center electricity use. U.S. public cloud services spending was estimated above $432 billion in 2024. The country also accounted for about 45% of global data-center electricity use in 2024.

Europe is a major cloud market with uneven adoption. European public cloud spending was forecast at about $229 billion in 2025 and about $452 billion by 2029. The United Kingdom’s cloud infrastructure market was estimated at about £7.0 billion to £7.5 billion in 2022, with AWS and Microsoft together holding roughly 70% to 80% of the market.

China is one of the largest national cloud infrastructure markets. Mainland China cloud infrastructure spending reached about $11.6 billion in the first quarter of 2025 and about $14.7 billion in the fourth quarter. China also accounted for about one-quarter of global data-center electricity use in 2024.

India remains a fast-growing public cloud market. Public cloud spending in India was estimated at about $13.7 billion in 2025 and forecast to reach about $17.5 billion in 2026. India’s public cloud services market was forecast to reach about $30.4 billion by 2029.

Key takeaway: Regional cloud activity is concentrated in large technology markets, while growth continues in fast-expanding markets such as India.
