If you needed proof that AI is fundamentally changing how software gets built, look no further than this: Microsoft — the company that owns Azure DevOps — just moved 1,600 of its own projects to GitHub specifically to access better AI tools.
Let that sink in for a moment. The world’s largest software company decided that where it stores its code matters so much for AI capabilities that it migrated an entire division — over 3,100 developers — in just six months.
A Little Background
Microsoft has two major platforms for software development: Azure DevOps (its veteran platform, battle-tested for a decade) and GitHub (which Microsoft acquired in 2018). For years, many of Microsoft’s own teams used Azure DevOps. It worked. It was reliable.
But then AI changed the equation.
GitHub is where GitHub Copilot — Microsoft’s AI coding assistant — lives and breathes most deeply. As AI coding agents evolved from “helpful suggestion tool” to “autonomous coding team member,” the advantage of being on GitHub grew significantly. Engineers on GitHub could access the latest AI agents automatically. Those on Azure DevOps had to wait, or work around limitations.
So Microsoft’s CAP division (responsible for Copilot products, no less) made the pragmatic call: move the code, gain the AI advantage.
The New Rule: Where Your Code Lives Affects What AI Can Do With It
This is the insight that every business should take away from this story.
We used to think of code repositories as storage — a place to keep your work, like a filing cabinet. The choice of which filing cabinet was mostly about cost and familiarity.
That’s no longer true. Today, the platform where your code lives directly determines which AI capabilities your team can access. It’s not just about storage anymore — it’s about the intelligence layer that wraps around your code.
Microsoft discovered that moving repositories to GitHub gave their engineers immediate access to AI agents that could:
- Automatically scan code for security vulnerabilities
- Open issues and route fixes to an AI coding agent to resolve
- Review pull requests with intelligent feedback
- Create what one Microsoft blog called “a digital workforce of agents working alongside developers”
That last phrase is worth dwelling on. Not tools that assist developers. A digital workforce working alongside them. The distinction matters.
What This Means If You’re Not a Tech Company
You might be thinking: “We’re not moving code repositories — we’re a [law firm / retail business / healthcare company / whatever].” Fair. But the underlying lesson applies everywhere.
The platforms and tools you use increasingly determine your AI ceiling. The businesses investing now in modern, AI-friendly infrastructure — whether that’s code, data, workflows, or operations — will have a significant advantage in the next few years over those that don’t.
Microsoft moved 1,600 projects in six months with just two dedicated leads and a small team. The scale of effort was smaller than you’d expect. The upside was immediate.
That’s the pattern we see over and over: the activation energy is lower than businesses assume, and the return comes faster than expected.
The Takeaway
You don’t need to be Microsoft to ask the right questions. The questions worth asking right now are:
- Are the platforms and tools we use today AI-ready?
- Where are there friction points that modern infrastructure could eliminate?
- What would our team be capable of with AI working alongside them?
The answers often point toward straightforward changes that unlock disproportionate value. That’s exactly the kind of work we love helping businesses think through.
