Microsoft turns to AWS as GitHub faces AI capacity crunch

Microsoft is supplementing GitHub's infrastructure with Amazon Web Services capacity to handle a surge in AI-driven coding activity, despite originally planning to fully migrate the platform to its own Azure cloud by 2027. The dramatic increase in commits—from 1 billion in 2025 to a projected 14 billion in 2026—has forced GitHub to redesign for 30X scale rather than the initially planned 10X increase, making operational reliability a higher priority than avoiding payments to its cloud rival. This multi-cloud approach reveals that AI coding has transformed developer tooling from a software feature competition into a hyperscale infrastructure challenge.
