Betting systems operate under high load and require instant data processing: live bets, streaming events, calculations and the interface must be synchronized in real time. That is why caching systems (Redis) and message brokers (Kafka, RabbitMQ) play a key role in the architecture. They provide speed, stability and scalability critical to gameplay.
Why do you need a cache in betting
Redis is used as high-performance in-memory storage for:- Caching matches, coefficients, event statuses
- TTL data storage (bet timers, live updates)
- Quick access to user sessions, shopping carts, stories
- Rate-limiting, betting limits, anti-fraud
- Buffering between slow bases and interface
Redis is used in pub/sub mode for instant alerts between microservices.
What message brokers do
Kafka and RabbitMQ manage data flows between microservices and external providers:| Use Case | Kafka | RabbitMQ |
|---|---|---|
| Stream of sporting events | High throughput | Limited by volumes |
| Update of coefficients | Great fit | Suitable for queues |
| Notifications, alerts | Excessively | Perfect in simple scenarios |
| Analytics and logging | Streaming at ClickHouse | Better Kafka or log collectors |
Kafka vs RabbitMQ - the choice depends on the task
| Criterion | Kafka | RabbitMQ |
|---|---|---|
| Throughput | Very high (mln msg/sec) | Average |
| Order and order | Guaranteed | It is supported |
| Message storage | Long-term (on disk) | Short term (memory/disk) |
| Load management | Perfectly scalable | Easy to install and configure |
| Perfect for | Threads, logs, real-time API | Backend, notifications, queues |
Examples of architectural solutions
Redis + PostgreSQL: fast delivery of matches with backup to the database
Kafka + Go services: event reception and coefficient streaming
RabbitMQ + Node. js: processing bonuses, fluffs, e-mail events
Kafka → ClickHouse: streaming analytics, live betting tracking
What does it give the platform
Event response - within milliseconds- Unloading DB and API due to caches and queues
- Scalability of microservices without a hard bundle
- Increased reliability: failures do not affect the entire system
- Ability to build real-time analytics and alerting
Caches and brokers are the real-time core of betting systems. Redis provides lightning-fast data access, Kafka and RabbitMQ manage event flows, and together they enable scalable, fault-tolerant and stable platform behavior in live load. Without them, today you cannot build a single serious betting product.
