Yeah, bandwidth costs is a thing that turns me off about AWS too and then a bunch of proprietary services too, so then you have to rewrite your application if you used some of them and wanting to move providers. However if you want to move fast and not worrying about some of the behind the scenes and have a budget for it, I can see how some large companies and well funded startups love AWS, even though there's sometimes cheaper and more open options.

Do you actually use it?

I’ve been a Linode customer for at least 5 years, and yes, I’ve used a large percentage of that cap on a few occasions. It’s real, if that’s what you’re implying. I use them over other options because their value and simplicity are outstanding.

Similarly with Hetzner, they give you 3 TB with their 2.5 € VMs and let you use it.

Unfortunately I've noticed that their "unmetered pipe" offering is quite a downgrade, as it's only 10 Mbit.

EDIT: Sorry, I'm wrong. All dedicated servers have 1 Gbit unlimited uplinks. I'm not sure why I keep getting confused on this point, their support has confirmed this fact many times to me.

The problem is Hetzner's sever are in EU only. Although I guess they could be used for cheap file server?
