Most of this stuff runs on autopilot once it's set up, which is why these companies have such huge margins.

That rounding error in accounting is also a monthly charge, and it sometimes happens that you get a spontaneous demand for $50K in a week and $200K in the next year. That could buy you enough hardware to run a chat for every school hacking club in the world, and a sysadmin to manage it.
