Global Gaming Infrastructure — 500K CCU at 48ms Latency
The Challenge
Mobile gaming studio needed real-time multiplayer backend for global launch. Previous infrastructure couldn't handle more than 10K concurrent without mass disconnects.
Previous vendor crashed at 10K concurrent connections
Game requires <50ms latency for competitive fairness
Launch planned in 12 regions simultaneously
Matchmaking needed to support skill-based and geographic routing
Our Solution
Custom WebSocket infrastructure on EKS with Redis Cluster for game state pub/sub, NLB for sticky sessions, and a custom matchmaking service with geographic awareness.
Deployed WebSocket pods with horizontal scaling to 200+ replicas
Redis Cluster with 6 shards for game state pub/sub
NLB with target group stickiness for connection persistence
Custom matchmaking service with skill + latency-based routing
CloudFront for static asset delivery in 12 regions
