"Scaling League of Legends Chat to 70 million Players" by Michal Ptaszek

Would you ever play an online game if you were not able to communicate with your teammates? Isn't it fun if you can make new friends, arrange pre-made games and celebrate your victories with people you like to play with? Riot Games' League of Legends handles millions of online players at any given time. Each chat server is responsible for routing over 1 billion real time events a day. In order to support the overwhelming user base and be prepared future growth, as well as pave the road for the upcoming features, chat infrastructure had to be designed and built with the utmost care, so that it would never fail the players. In this talk I would like to present how we achieved linear scalability, improved the overall fault tolerance, created a framework for real time code upgrades and got ready for the new features we want to ship. I will also discuss in detail why we chose to use Erlang as a foundation for the system, and why we migrated our data from MySQL to Riak.
