For most apps, delivery has been some equivalent of “git push heroku main” and setting a DNS record for like 15 years. That’s especially true for most of the apps being vibe coded today.

The fact that “cloud engineer” is still a job suggests that the simple case is not the one driving employment. There are definitely more devops/sre/cloud engineer roles today than there were in 2009 (and I’d be willing to wager you if you included pre-devops sysadmins in that count, there’d still be more total roles today).
