Dynamic HAProxy at Scale: Roblox's infrastructure evolution

Roblox supports nearly 100 million daily active users, which creates massive challenges when migrating services at scale. This presentation walks through our journey from bare metal to orchestrated HAProxy Enterprise deployments, highlighting the initial transition challenges and how we resolved them with custom orchestration solutions. The dynamic update module proved to be an indispensable tool, but it's the ecosystem we built around it that truly transformed our operations.

What you'll learn:

• How Roblox manages HAProxy Enterprise at massive scale (supporting ~100M daily active users)
• Our evolution from static to dynamic configurations and the tooling we built
• How we leverage HAProxy Enterprise's dynamic update module and HAProxy Enterprise WAF as secret weapons
• Implementation of GitHub Actions to auto-distribute mapping, reducing manual toil
• Our custom deployment tooling with automated rollback capabilities

Join us to gain insights from real-world experience managing large-scale infrastructure migrations using HAProxy, and see how we solved complex challenges while working within the constraints of our fast-moving organization.
