The most concise answer is 'tooling'. We have a DevTools team that builds the SDLC and automated testing infra, all tightly integrated into MS Visual Studio. That lets the thousands of developers focus on productive coding.

Just watched it. Thanks, it was indeed a great talk, and indeed a lot of tooling.

Do you have any extra writeup to suggest?

There isn't a ton of detailed public information on this kind of stuff. My talk focused on the general principles of our approach, rather than the myriad of features and optimizations necessary at such a large scale.

A good next step would be reading the 2016 ACM paper "Why Google Stores Billions of Lines of Code in a Single Repository" [1] then reading a recent HN discussion [2]. That has a ton of good links.
