4 months ago they surpassed 3.4 million concurrent players[1]. 100 players per server, at least 34,000 game instances (assuming 100 per game, which isn't always the case since games quickly fall down to ~50 players in a few minutes) which all report statistics of games to databases, etc. Sessions, logins, reports, kills, replays.... those add up.

Yes but those are all shardable, cacheable and mostly asynchronous. The blog post is about how you can build a large world wide game as if it was a single data center with low latency.

And so is MMO data (cacheable in a ton of cases, shardeable (the article even mentions this one!)).
Specifically, it mentions how sharding is _not_ ideal for this game.
