the 1 admin to 600 machines quoted as the high end for traditional IT datacenter is, in my experience, a murky number. It's usually a ratio of people/virtual machines, not physical machines. When you remove the VM smokescreen and count physical boxes it's more like 1 person/100 machines, which is abysmal. I've seen order-of-magnitude people efficiency increases with automation like we're discussing here.
