I always am curious when I see this. I've planned and deployed master setups in two separate 10^4 node count companies now. In my experience the number of hosts doesn't really matter (figuring out an architecture that will work with availability zones etc only takes a couple weeks). The real work is figuring out how to normalize and govern the repos. I haven't seen any sane ansible repo once it's beyond a few senior contributors because it's so easy to do whatever you want. Ansible is the ultimate small business tool, but it works very poorly in large companies.

We're at the 10^4 node count but the team managing it is still at the 10^1 size. That's how, basically. You have to make large investments into automation, code review process and time to make continuous improvements (because things do slip through).

There's style guides, linting, commit checks...
