alt Hacker NewsUnless we're talking actual PaaS (Heroku, Render, Railway, etc), the cloud also needs a dedicated skillset, so "cloud" doesn't remove the need from a sysadmin.
If you can get (and trust they do it right) developers to do AWS or Kubernetes, you should be able to trust them to do conventional Linux sysadmin on a bunch of dedicated boxes.
I suspect you're either severely underestimating what the cloud offers or thinking of a very narrow set of software businesses.
A full stack/backed dev is more than capable of learning both, but one of those has way more foot guns than the other.
