Nope, these days servers pretty much run themselves. One just needs to make sure hardware is not failing, and that is pretty much it. Really. Speaking from experience.
Sure, though we're talking about a 6 figure/mo cloud spend. That's dozens or hundreds of servers. (+network config etc) I run our tech stack, and I can stand up instances pretty easily, but I had to rack and stack, manage power, bring in leased lines, I'd be well outside of my skill set.
