Funny, I see it the opposite way. Managing VPS, VM and dedicated root servers is something that a developers often have to deal with just at home, doing it with remote servers is just the same skills but applied to bigger servers, remote setting, more instances available than your personal computer, easier to congest bandwidth and so on. If you're a developer you're already a sysadmin, no matter if you use Windows, macOS or Linux. It's just a matter of depth in your sysadmin skill. People who manage huge "cloud" installations feels more like what the traditional sysadmin role was. Everything is so different than your personal setup, you have no use of the same skills outside of that particular provider, and there are many concepts that you have to deal with that you never deal with locally.
