Event-Driven Architecture: Building Reactive Applications

Event-driven architecture (EDA) decouples producers of events from consumers, enabling reactive, scalable systems. Common components include event producers, event brokers, and consumers.

Key patterns

• Pub/Sub with brokers (Kafka, RabbitMQ)
• Event sourcing & CQRS for complex domains
• Idempotency and retry strategies

When to use EDA

Use EDA for systems requiring high scalability, asynchronous workflows, and loose coupling between services.
