Providers like OVH, Hetzner, etc will provide you servers and handle maintenance just like cloud providers, and it turns out that in both cases you need to hire sysadmins (or "DevOps" engineers). You don't need extra staff unless you do actual on-prem which very few companies need (most can be served by a provider like the aforementioned ones).
