Yes. But people use "you have to hire people to manage it" as an argument against on-perm. When in practice, most companies hire "devOps engineers" or "cloud engineers" to manage their cloud infrastructure too. And those salaries seem higher than the infrastructure/ops guys of yesteryear. So resource cost isn't really an advantage.
don't forget the "cloud cost engineer", just to figure out how much it will cost to run the 20 services that should have been part of your app with random ways of billing the usage of it
