How Big Is the Cloud Infrastructure Market?

Global cloud infrastructure service spending reached $99 billion in Q2 2025, representing a 25% increase compared to the same quarter in 2024. This added more than $20 billion in revenue compared to the previous year.

For the full year 2025, cloud infrastructure service revenues are projected to exceed $400 billion for the first time. This is why competition in this market remains fierce despite its massive size.

What Is AWS's Market Share?

Amazon Web Services (AWS) holds 30% of the global cloud infrastructure market as of Q2 2025. AWS has maintained its position as the market leader since establishing itself as an early pioneer in cloud infrastructure services.

Despite strong competition from Microsoft and Google, AWS remains ahead of its closest competitor, Microsoft Azure, by 10 percentage points.

What Is Microsoft Azure's Market Share?

Microsoft Azure holds 20% of the global cloud infrastructure market in Q2 2025, which makes it the second-largest provider. Azure trails AWS by 10 percentage points but maintains a significant lead over the third-place Google Cloud.

What Is Google Cloud's Market Share?

Google Cloud holds 13% of the global cloud infrastructure market as of Q2 2025, securing third place among cloud providers. Google Cloud is the smallest of the "Big Three" but still commands a larger market share than all other competitors combined outside of AWS and Azure.

How Fast Is the Cloud Market Growing?

The cloud infrastructure market is experiencing strong growth, with Q2 2025 revenues growing 25% year-over-year. This growth has actually re-accelerated in recent quarters, driven primarily by the AI boom and associated computing requirements.

GenAI-specific cloud services showed particularly explosive growth, expanding 140-180% in Q2 2025 according to Synergy Research Group's chief analyst John Dinsdale. AI is also contributing to enhanced growth across the broader portfolio of cloud services beyond just GenAI-specific offerings.

What About Other Cloud Providers?

Outside the Big Three, cloud infrastructure market share drops significantly:

  • Alibaba Cloud holds 4% of the market
  • Oracle has 3% market share
  • Salesforce, IBM Cloud, and Tencent Cloud each hold 2%

All other cloud infrastructure providers combined account for less than 10% of the total market, illustrating the strong dominance of AWS, Azure, and Google Cloud.
