CMA Report: AWS and Microsoft Dominate UK + EEA Cloud Market in 2024

The UK Competition and Markets Authority (CMA) has released its final decision on cloud services, providing one of the clearest views yet of the UK + EEA cloud market landscape.

The report defines cloud services as Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) — the core layers that power most cloud-based applications and modern IT infrastructure.

📊 Cloud Market Share Overview (2024)

According to the CMA:

• AWS and Microsoft Azure each hold 30–40% of the market.
• Google Cloud follows with 5–10%.
• Oracle Cloud and IBM Cloud each remain under 5%.
• Combined smaller providers make up roughly 15–17%.

💼 What This Means for Cloud Learners and Professionals

The CMA’s findings confirm what many in the industry already sense — AWS and Azure remain the dominant platforms across the UK and EEA.
For professionals choosing which platform to learn or specialize in, this market share data helps clarify where the largest job opportunities and customer adoption exist.

• AWS and Azure: Most enterprises run workloads here, making them ideal starting points for DevOps engineers, cloud architects, and platform specialists.
• Google Cloud: Growing steadily and popular for data analytics, AI, and Kubernetes workloads.
• Oracle Cloud & IBM Cloud: Smaller market share but valuable for niche enterprise or hybrid environments (finance, legacy modernization, etc.).
• Smaller providers: Represent opportunities for multi-cloud skills and emerging markets, especially in edge computing or regional data hosting.

Total UK cloud spending reached £10.5 billion in 2024, growing nearly 30% per year since 2020.

As cloud adoption accelerates and AI-driven workloads expand, the ability to work across multiple platforms — or at least understand the differences between them — is becoming a key advantage.

🔍 PlatformStack Insight

The CMA’s report highlights how concentrated the market is, but also reinforces one key takeaway for learners:

Start where the demand is (AWS or Azure), then expand your skills across Google Cloud or Oracle to stay adaptable in a multi-cloud world.

Whether you’re pursuing certifications, building cloud-native skills, or exploring automation and DevOps, this data helps you invest your time where it matters most.
