To be fair, you should probably account for one or two mirror servers on hetzner for easier, lower latency fail over in case of hw failure (assuming you're talking about dedicated servers, not hetzner cloud). Of course with eg three servers, you might load balance acccross most of those during normal load, just make sure to have enough capacity left over to run with N less servers while you spin up a replacement and/or a disk is replaced etc).
Just for a more apples to apples comparison.
I guess the reason ppl don't "see" the insane premium clouds place on bandwidth is that bandwidth scales up with (presumably paying) customers. So as long as you're not streaming 4k video... You're happy to let the cloud eat out of the bit of your profits that "scales up".
We are heavily invested in AWS. AWS is not cheaper, but it doesn't mean it's prohibitively expensive when you consider everything it offers. What people tend to ignore are the other things it offers. For example, the parent talks about data transfer costs, but that's just one aspect of cost.
The real big cost in any organization is head count. And while a load balancer is not difficult to setup and maintain the first time, managing it becomes time consuming in a large enough organization. Couple that with everything else...
If someone can replicate what AWS is doing at a lower cost, people would move to them. But there are few companies out there that come close. Bandwidth cost is generally not your biggest expense.
