Geopolitical Impact Analysis

Geopolitical disruption is increasing the cost and delivery time of physical infrastructure used to support public cloud services, including servers, storage systems, networking equipment, cooling systems, backup generators, power distribution units, and semiconductors. According to UN Trade and Development (UNCTAD), Red Sea disruptions forced ships to reroute around the Cape of Good Hope, reducing Suez Canal transits by 70% and vessel tonnage through the Gulf of Aden by 76% by mid-2024.

On the Shanghai–Europe route, spot freight rates increased 256% to USD 2,648 per TEU by February 2024, while the China Containerized Freight Index rose 120% between October 2023 and June 2024. Longer shipping routes increase fuel costs, insurance expenses, inventory requirements, and delivery times for servers, racks, power systems, and replacement components.

These factors can raise data-centre construction costs and delay cloud-capacity expansion. Trade policies are adding further pressure. In 2025, U.S. Section 232 tariffs on imported steel, aluminium, and derivative products increased from 25% to 50%. These materials are widely used in data-centre buildings, server racks, electrical enclosures, cooling equipment, cable trays, and backup-power systems. Energy costs are another major concern.

The International Energy Agency expects data-centre electricity consumption to increase by around 15% annually from 2024 to 2030. As geopolitical conflicts affect shipping routes, energy supplies, and equipment availability, cloud providers are likely to diversify suppliers, maintain larger hardware inventories, select lower-risk locations, and secure longer-term electricity contracts.

Regional Analysis

North America led the global public cloud market in 2025, accounting for 37.4% of total revenue, equal to approximately USD 301.6 billion. The region benefits from a strong base of hyperscale data centres, enterprise software companies, financial institutions, technology firms, retailers, and users of AI, analytics, cybersecurity, and digital platforms. The United States remains the main growth driver.

According to UN Trade and Development (UNCTAD), announced U.S. greenfield data-centre projects reached about USD 38 billion in the first three quarters of 2025, while semiconductor projects attracted another USD 137 billion. These investments are expanding computing, storage, networking, and AI capacity.

The International Energy Agency (IEA) also expects U.S. electricity demand to increase by about 2% annually during 2025–2027, with rising data-centre demand identified as a key factor. Asia Pacific is expected to be the fastest-growing regional market, supported by rapid digitalisation across China, India, Southeast Asia, Japan, South Korea, and Australia.

UNCTAD reported that the Republic of Korea attracted approximately USD 21 billion in announced greenfield data-centre investment during the first three quarters of 2025, making it the third-largest recipient globally. India received around USD 7 billion, while Malaysia attracted about USD 4 billion.

Market Dynamics

Drivers

AI Computing Demand

AI is becoming a major growth driver for public cloud services because model training, inference, vector databases, high-speed networking, and data pipelines require large computing capacity. According to the IEA, global data-centre electricity consumption is projected to increase from about 415 TWh in 2024 to approximately 945 TWh by 2030, with AI workloads contributing strongly to this growth. Consumption could reach around 1,200 TWh by 2035.

Enterprise AI adoption is also increasing recurring cloud demand. Eurostat reported that 20% of EU enterprises used AI technologies in 2025, while OECD data shows cloud adoption averaging about 49% among firms with at least 10 employees.

As organisations shift AI computing, data management, and cybersecurity workloads to usage-based cloud platforms, spending moves from one-time hardware purchases toward recurring cloud services. This trend could provide an estimated +2.4% incremental CAGR upside to public cloud market growth.

Restraints

Power Grid Connection Limits

Electricity availability is a major restraint for public cloud expansion because new data-centre regions require sufficient generation, transmission, and grid-connection capacity before operations can begin. According to the IEA, global data-centre electricity demand is expected to rise from about 415 TWh in 2024 to approximately 945 TWh by 2030.

In the United States, data-centre electricity demand could increase by around 240 TWh between 2024 and 2030, representing nearly 130% growth. Grid development often takes several years, while data-centre demand can increase much faster.

The U.S. Federal Energy Regulatory Commission reports that interconnection queues contain more than 2,600 GW of proposed generation and storage capacity. Limited grid access can delay new facilities and increase spending on backup generation, private power systems, and long-term electricity contracts. These constraints could reduce baseline public cloud market growth by an estimated -1.7%.

Challenges

Cybersecurity Skills Shortage

Cybersecurity capability remains a key growth challenge for public cloud adoption because cloud environments require skilled teams for configuration, identity management, monitoring, incident response, and application security.

According to ISC2, the global cybersecurity workforce gap reached approximately 4.8 million professionals in 2024, highlighting a major shortage of specialised talent. The skills gap increases labour costs, slows complex cloud migrations, and raises dependence on managed-security services.

Financial institutions also face higher operational and concentration risks as critical technology services become more centralised. Without faster improvement in cybersecurity capabilities, this challenge could create an estimated -1.3% drag on maximum market growth, although the overall public cloud outlook remains positive.

Opportunities

Sovereign Cloud Platforms

Sovereign cloud remains a future growth opportunity as many public-sector, defence, healthcare, and financial workloads still require local data control and strict compliance before moving to the cloud. The EU Data Act became applicable on 12 September 2025, while cloud switching charges must be eliminated by 12 January 2027, which could reduce migration barriers.

OECD data also shows that cloud adoption ranges from only 16% to more than 70% among firms with at least 10 employees, leaving significant room for compliant local cloud services. Sovereign cloud platforms can help governments and regulated industries improve security, data governance, and operational resilience.

Providers that establish local infrastructure, partnerships, certifications, and dedicated operations could benefit from higher-value managed-service contracts. Wider adoption of these platforms could create an estimated incremental CAGR upside of around +2.0% above the baseline, particularly as regulated workloads gradually move toward locally controlled cloud environments.
