Cost breakdown here: https://docs.google.com/spreadsheets/d/1Si3PMUJGR9KrpE5lngSk... I hope OVH would donate some compute/machines to lichess. It would help lichess a lot financially. It would be good publicity for OVH and I think it would be a drop in the ocean on their balance sheet.
It's interesting that he spends so little on servers. 1 billion chess games per year, often with >20k concurrent users and and some very heavy-duty engine analysis occurring for some proportion of these games and they only spends $56k. I have seen startups with only hundreds of customers spend 10x this on AWS by copying the fancy tools used by tech giants. It is also interesting how little the creator pays himself ($…
$1000/mo on a few frontend servers for only 20K concurrent users seems excessive.
I've seen simple $40/mo droplets handle 50,000 concurrent websocket connections with minimal latency without breaking a sweat.
$2000/mo on databases is also nuts, unless you're storing hundreds of terabytes at high redundancy levels.
