Real-time betting is one of the most technologically complex segments of the iGaming industry. Taking live bets, working with streaming sports data, instant coefficient changes and calculations - all this requires a highly loaded, fault-tolerant and scalable architecture that works 24/7 without delays.
Live architecture features
Instant reaction to events - goals, deletions, timeouts must be updated in milliseconds- Limited window on the bet - calculation should be as accurate and fast as possible
- Incoming data stream - tens of thousands of events per minute from feed providers
- Load stability - especially during top events (World Cup, finals, derby)
Data Streaming
| Component | Description |
|---|---|
| Data Feed Ingestion | Integration with providers (Sportradar, Betgenius, etc.) via API/WebSocket |
| Calculation of coefficients | Real time based on algorithms and margin |
| Interface update | Via WebSocket or push (without reloading the page) |
| Caching and buffering | Redis, Kafka, NATS - for stability and speed |
System architecture
Microservices by areas of responsibility - rates, calculations, broadcasts, reports- Event-driven и stream-first подход — Kafka, gRPC, REST + WebSocket
- API-first logic - openness to integrations, mobile applications and partner channels
- CDN and geo-distribution - so that a player from Brazil or Germany receives an equally fast response
- Failover systems and health-check mechanisms - automatic restart in case of failures
Scalability and fault tolerance
Scale horizontally by node (no downtime)- Isolation of critical services (calculation, rate, fee) into separate containers
- Monitoring & Observability: Grafana, Prometheus, ELK, Jaeger
- Automatic SLA monitoring for API response time
Technologies
| Area | Tools and Solutions |
|---|---|
| Backend | Go, Node. js, Java, Elixir |
| Threads and Events | Kafka, NATS, Redis Streams |
| Realtime | WebSocket, SSE, SignalR |
| Data warehouse | PostgreSQL, ClickHouse, Redis |
| DevOps | Kubernetes, Docker, GitLab CI, Terraform |
| Balancing | NGINX, HAProxy, Cloudflare |
High-load architecture is the basis of Live-betting. The higher the speed of data processing, stability under load and accuracy of bets, the higher the confidence of the players, the depth of the sessions and the income of the platform. Without a stream architecture and competent infrastructure optimization, scalable and reliable live-betting is impossible.
