According to https://discourse.nixos.org/t/nixos-foundations-financial-su..., they have 450TB and 29.5TB of S3 egress/month. By my math, assuming the Nix Foundation goes in through our front door, talks to no sales people, and pays list price, that's $2k/month.
You would replace the Fastly CDN with Storj, correct? Your link mentions 1500TB of Fastly traffic, which would cost $12k with Storj. Not sure if this is related to parent's 3TB/day number, but I went with that when I estimated the $8k.
I think the best cloud solution might be something like Storj + Fastly or Cloudflare end-to-end. But I'm really curious how much could be chopped off if you tried to solve this on-prem.
Storj + Fastly is genuinely a pretty good combo. There are certainly some things Fastly does that we don't do (besides being more specifically a CDN, they also have compute@edge, etc). We have a good relationship with Fastly (e.g. https://docs.fastly.com/en/guides/log-streaming-storj-dcs)
But yeah, I don't know how the Nix Foundation is getting their Fastly traffic paid for, maybe that's in/out of scope. Certainly they should keep Fastly if it makes the overall thing cheaper. Having a distributed origin (us) to dedicated edge cache (Fastly) makes for a strong distribution story.
