Microsoft Taps AWS to Ease GitHub Capacity Crunch From AI Boom
The software giant is turning to its biggest cloud rival to handle a surge in code commits that has strained GitHub's infrastructure and caused repeated outages.
Microsoft is enlisting Amazon Web Services to provide additional computing capacity for GitHub, its code-hosting platform, as AI-driven development activity overwhelms existing infrastructure, according to two people familiar with the arrangement.
The move represents a significant shift for Microsoft, which had planned to migrate GitHub entirely to its own Azure cloud service by 2027. GitHub, acquired by Microsoft in 2018, previously operated its own data centers as an independent company. Now surging demand from AI coding tools is forcing Microsoft to seek capacity from its primary cloud competitor.
Why it matters
This arrangement underscores how intense AI compute demand is reshaping competitive dynamics in the tech industry. Microsoft is choosing service reliability over competitive advantage — a pragmatic decision when GitHub faces dozens of major outages in 2026 and mounting pressure from AI-native competitors like Cursor and Anthropic's Claude Code. The deal also signals that even companies investing hundreds of billions in data center expansion cannot keep pace with AI workload growth through internal resources alone.
The scale of GitHub's capacity challenge
GitHub Chief Operating Officer Kyle Daigle disclosed in April that code commits — records of changes that indicate development activity — were projected to reach 14 billion in 2026, up from just 1 billion in 2025. AI coding assistants have enabled developers to produce software at unprecedented rates, flooding GitHub's systems with new code.
The infrastructure strain has manifested in frequent service disruptions. Mitchell Hashimoto, cofounder of HashiCorp, wrote in April that GitHub was "no longer a place for serious work if it just blocks you out for hours per day, every day."
A Microsoft spokesperson confirmed GitHub is working with multiple cloud providers but declined to specify Amazon's involvement. The spokesperson said the "incredible spike in agentic development that began late last year has tested our infrastructure's limits," adding that Microsoft is "both accelerating our move to Azure and continuing to explore a multi-cloud strategy."
A broader industry pattern
Microsoft's decision follows similar cross-competitor deals driven by AI capacity constraints. Earlier this month, SpaceX and Google announced an agreement worth $920 million monthly for AI compute capacity from October 2026 through June 2029. Google's cloud division also recently agreed to sell AI computing resources to Anthropic, despite Google being an Anthropic investor and competitor.
An Amazon spokesperson said the company doesn't comment on specific clients but noted that "customers choose AWS because they need global infrastructure that performs reliably, securely, and efficiently at scale."
Microsoft has projected capital expenditures of $190 billion for calendar year 2026, primarily for data center expansion. However, many projects face delays, and Microsoft must allocate compute capacity across numerous AI initiatives beyond GitHub. According to audio from an internal meeting reviewed by Business Insider, a Microsoft executive discussed the need to overhaul GitHub to compete with emerging AI coding platforms.
