Back in 2018, where I worked there was an operations team. “Ops”, we called them. In that decade, this company was behind the curve, but not far from typical. We were just starting to think about AWS. At the tail end of my time there, we were just starting to adopt AWS for some internal-only systems. But from what I’ve heard from friends who worked at more mature companies, it wasn’t uncommon in that era to have an operations team that owned production.
