> Maintaining 40 racks of hardware takes a surprisingly trivial amount of time aside from regular OS management.

I think it's only surprising to people who have been listening to the "it's awful" mythology or believe in a much higher than reality hardware failure rate.

I think the worst I've ever seen was with spinning disks from the time of the Thailand flooding, and even those were only 10-15% AFR and only for certain models.

Absent that kind of black swan event, one can easily engineer around even disk failures, such that failed ones can just be spun down and left in place, and, of course, one can do the same with server-level redundancy.

If the labor burden were actually onerous, it would be easy enough to avoid it, but I think it's telling that such techniques are so rarely spoken of.

The labor of running your own stuff isn't that bad. And the labor of running AWS is at least the same, if not more.

I really don't see how AWS wins in that argument.

Only when there's no argument in the first place and the decision is already made.

I don't think I've ever seen AWS (or any public cloud) require more labor in terms of hours/persons, but I routinely see it require labor that's more expensive, since we're back to a market where programmers are paid more than sysadmins.
