I worked at a company like this, I was an intern with wide eyes seeing the migration to git via bitbucket in the year ... 2018? What a sight to see.

That company had its own data center, tape archives, etc. It had been running largely the same way continuously since the 90s. When I left for a better job, the company had split into two camps. The old curmudgeonly on-prem activists and the over-optimistic cloud native AWS/GCP certified evangelist with no real experience in the cloud (because they worked at a company with no cloud presence). I'm humble enough to admit that I was part of the second camp and I didn't know shit, I was cargo culting.

This migration is still not complete as far as I'm aware. Hopefully the teams that resisted this long and never left for the cloud get to settle in for another decade of on-prem superiority lol.
