This presentation will describe the challenges, benefits and overwhelming success of deploying a PoP network using HAProxy. You will learn how Stadia Maps uses HAProxy to increase and track performance, ensure reliability and uptime, and enforce authentication and authorization for our mapping services. Specific topics covered will be replacing active authentication with ACLs, using HAProxy’s syslog output to track usage and enforce quotas, using SRV records to route (and reroute) traffic, and the challenges encountered running an IP failover-based setup at scale.
