What do you do when they're on vacation/sick/sleeping?
Thing is, I really want us to host our own stuff. For one thing if you don't host anything you lose all competence and then you really are beholden to your cloud provider.
But it seems to be that we are in this situation until someone figures out how to comodify servers - and server orchestration - to the point where this stuff gets cheaper to manage again.
This pendulum always swings. No sooner will we control our own hardware again than someone will come up with a new way to centralize it.
With a bare metal server you have to manage all of that.
It's not a bed of roses in the physical world either, but you're simply wrong to say it's easy in the "Cloud" and hard in a DC/Bare Metal.
I find it amusing that people pretend without bare metal, you'll get all of that person's time back.
