Building Multiplayer Game Servers

Master the art of building high-performance, scalable multiplayer game servers with Go. From real-time networking to handling thousands of concurrent players.

Why Game Servers Are Different

Game servers aren't just web servers with multiplayer features. They require specialized knowledge of real-time systems, networking protocols, and state synchronization.

Real-Time Requirements

Game servers must maintain 60+ updates per second with sub-50ms latency. Every millisecond counts in competitive gaming.

State Synchronization

Keeping all players in sync while handling network issues, packet loss, and varying latencies requires sophisticated algorithms.

Massive Scale

Modern games support thousands of concurrent players. Learn how to architect systems that scale horizontally and handle peak loads.

What You'll Master

Core Concepts

  • • Game loop architecture and tick-based systems
  • • UDP vs TCP trade-offs for real-time games
  • • State synchronization and client prediction
  • • Lag compensation and rollback systems
  • • Anti-cheat and server authority

Advanced Topics

  • • Spatial partitioning for large worlds
  • • Matchmaking and lobby systems
  • • Database design for game persistence
