Архитектура игровых серверов
Game server hosts authoritative game state. Правильная архитектура — foundation fair play и scalability.
Authoritative model
Все game logic на сервере. Клиент просто отправляет actions и рендерит результат. Prevention client-side cheating. Server-side RNG. Server validates каждый action. Even in single-player casino games — server authoritative.
State management
Session state: active bet, current round. Persistent: player balance, history. In-memory для performance (Redis, native memory). Persistence: async writes с eventual consistency. Recovery: restore state после crashes.
Networking
WebSocket для real-time. Binary protocols для performance (MessagePack, Protocol Buffers). Message queuing для reliability. Compression для bandwidth. Regional deployment для latency. CDN для static assets.
Scaling patterns
Horizontal: N instances behind LB. Sticky sessions или shared state. Game session sharding: player_id % N. Kubernetes scaling. Session migration при node failures. Multi-region для global players. Game-as-a-service (Agones для K8s).
