Yeah, currently hosting LLHLS edge nodes in US + EU and caching CDN worldwide. The base cost grows if you have an audience of e.g. 2000 live viewers for a 2mbps stream = 4gbps.
Could be a lot cheaper and less need for global distribution if low latency weren't a requirement. And by low latency I mean the video stream you watch is ~2s behind reality just like Youtube, Twitch, Kick, etc. If your use case is VOD or can tolerate 10s latency streaming, single PoP works fine.
The point is that if I chose Vimeo or AWS/GCP/Azure for this, at their bandwidth pricing my (in my opinion modest) usage would be costing tens of thousands of dollars monthly, which it most certainly does not.
Managed service pricing and the perception of it needs to change, because it feels like a sham once you actually do anything yourself.
