Traffic cost must be insane. Hope they have good hosting and won’t be paying through the nose and go broke.

Should be manageable and it is probably less than you would imagine. Just checked real quick: the isos load from download.bazzite.gg, which is a Cloudflare IP. So they are either using it as CDN or even more likely use Cloudflares R2 storage for isos - which would mean they pay for storage (~15$/TB) and operations, but not for egress. This is seems ideal for few but huge files.

So for a single iso (~7 GB) they would pay 0,105$ for storage monthly and additionally 0,36$ per million of class B operations (reads/downloads). Of course they host more than one ISO, but for this example it would have been downloaded about ~150000 times to reach the petabyte.

So yeah, the ISO download is probably less of a problem. (Disclaimer: lot of assumptions, check in with a bazzite dev for clarity)

Doesn’t $0.36 times 150,000 downloads come out to 54 thousand dollars, which is a lot of money?

Sorry, my bad. 0,36$ per million class b operations. Of course there will be slightly more operations than downloads (e.g. people/bots sarting downloads and aborting them), but still probably cheap.
