Microsoft Utilizes Amazon Web Services for GitHub AI Capacity Amid Surge
Microsoft is adding Amazon Web Services (AWS) capacity to its GitHub coding platform to address infrastructure strain and reliability issues. The move comes after an AI-driven surge in usage overwhelmed GitHub's existing compute resources, which Microsoft had intended to migrate entirely to its Azure cloud service by 2027. Despite the intense cloud market rivalry between Microsoft and Amazon, the decision reflects a broader industry trend of major tech companies seeking external compute capacity to meet the growing demands of AI development.
Microsoft is turning to Amazon's cloud services to alleviate capacity and reliability issues on its GitHub coding platform, which have emerged following an AI-driven surge in usage this year.
GitHub, acquired by Microsoft in 2018, was initially planned to fully transition from its own data centers to Microsoft's Azure cloud by 2027. However, a significant increase in demand driven by AI coding tools has led to a flood of new code, straining GitHub's infrastructure and resulting in dozens of major outages in 2026.
GitHub commits, a measure of development activity, were projected to reach 14 billion in 2026, a substantial increase from 1 billion in 2025, according to Chief Operating Officer Kyle Daigle. To manage this surge, Microsoft is supplementing its capacity with Amazon Web Services (AWS).
A Microsoft spokesperson confirmed GitHub is engaging with multiple cloud providers to meet demand, stating the company is "accelerating our move to Azure and continuing to explore a multi-cloud strategy." An Amazon spokesperson declined to comment on specific clients but noted that customers choose AWS for its reliable and scalable global infrastructure.
The reliance on a primary cloud rival like Amazon highlights the intense demand for AI compute capacity across the tech industry. Similar arrangements have been observed, such as a recent deal where Google will pay SpaceX $920 million monthly for AI compute capacity from October 2026 to June 2029, and Google Cloud's agreement to sell AI compute capacity to Anthropic.
GitHub has faced increased competition from AI tools like Cursor and Anthropic's Claude Code. Microsoft projected capital expenditures for the 2026 calendar year to reach $190 billion, largely for data center expansion, though many projects face delays. According to Business Insider, a Microsoft executive discussed internally the need to overhaul GitHub to remain competitive.
