#2The main lichess engine (lila, open source) is a single monolith program that's deployed on a single server. It serves ~5 million games per day. But there are a several other pieces too. They discuss the architecture here https://www.youtube.com/watch?v=crKNBSpO2_I
BTW consider donating if you use lichess.

Wow. ~US$40k/mo running costs, with about US$5k/mo for server hosting:
It looks like the servers are individually managed via OVH or similar, rather than running their own gear in co-location or similar. Wonder why?

Surprising numbers, and really goes to show how cheap the hardware/software side is for this sort of thing if you do it right.
I wonder what the "Misc dev salaries" is for - only curious because it's a flat $5k

Heh heh heh.
To me those numbers seem on the high side as I'm (personally) used to (for cheap projects) scavenging together stuff from Ebay before deploying to a data centre. ;)

lichess is hardly a "cheap project" though :P It's one of the most popular chess platforms

Sure, but they seem to be extremely budget constrained. ;)

Easy: If something is wrong with the physical gear it's OVH's problem rather than theirs. It also means no one has to ever go to the data center which is probably important for a geographically distributed team (I assume they are). Cheap, no-frills cloud is extremely underrated, IMO.

#10This response and post-mortem is superior to most commercial services I have seen in recent years.
