Phoenix at Scale

Phoenix at Scale is the definitive guide to building, shipping, and operating high-performance real-time applications with Phoenix and LiveView-in production, under load, and at scale.

This book goes beyond demos and tutorials. It's written for engineers who need systems that stay fast, resilient, and observable when traffic spikes, users multiply, and failures happen at the worst possible time. You'll learn how to design real-time architectures that scale cleanly, deploy with confidence, and remain maintainable long after launch day.

Drawing from real-world production experience, Phoenix at Scale shows how to push Phoenix and LiveView to their limits-without sacrificing reliability or developer sanity.

• Design real-time systems using Phoenix Channels, PubSub, and LiveView

• Scale LiveView applications without melting your servers

• Manage state, concurrency, and backpressure in high-traffic environments

• Build fault-tolerant systems that embrace the BEAM's strengths

• Instrument, observe, and debug live systems in production

• Deploy, upgrade, and operate Phoenix apps with zero downtime

• Avoid common scaling traps-and fix them when you're already in trouble

Whether you're building collaborative apps, dashboards, multiplayer experiences, or live data platforms, this book gives you the tactics and mental models needed to run Phoenix in the real world.
