Sort of. Google is also well known for having a dozen chat apps. What most people don't know is that there are also likely a dozen different libraries/utilities/interfaces performing near identical services just because an engineer or product team weren't 100% satisfied with what already existed. So yes, it's a monorep, but holy heck there's a lot of duplicative cruft.

> all code deployed to all servers This is the main point of the post. Google most certainly doesn't do this, even if they have all their code (or at least, all their private code) in one repo (piper).
