This has been my experience with my major enterprise company’s cloud transition as well. The ops payroll has only grown since the transition. And our company had 4 major platforms before transitioning to the cloud and now only has 3.
I won’t deny the cloud doesn’t have any benefits. Distributing services and DBs geographically is much easier than with Colo for example. But really yhwts where the cloud benefits really lie. Since everyone is spending all their money building services for the cloud, that’s where innovation in tech lies right now (although whether we need more innovation is indeed arguable, and whether one benefits from being at the vanguard of innovation is also an open question).
