The Player Accounts team at Riot Games needed to consolidate the player account infrastructure and provide a single, global accounts system for the League of Legends player base.

This provided higher fault tolerance and lower latency access to account data. In this talk by Tyler Turk (Infrastructure Engineer, Riot Games), we discuss this effort to migrate eight disparate database clusters into AWS as a single composite database cluster replicated in four different AWS regions, provisioned with terraform, and managed and operated by Ansible.
