And that's fine. Though as a counterpoint:

Which goes back to my point. You're comparing your home system, with something like one-9's uptime (90% availability over an entire year) with a cloud provider that is going to give you five-9's or better.

These are not the same things. And you are going to pay more for each additional 9 of uptime.

For your own stuff, yes, of course it can make perfect sense to host it yourself. I've got a personal server running on positively ancient hardware that still manages two-9's availability, and that's fine for my use case. But I wouldn't directly compare that to a cloud provider either.

I said my hardware raid failed, I'm still checking georedundancy / failover at sperate locations.
