Choosing a Message Broker: Kafka vs RabbitMQ

When building decoupled, event-driven systems, the messaging layer becomes the backbone of your architecture.

• RabbitMQ acts as a traditional smart broker. It pushes messages to consumers and deletes them once they are acknowledged. It is perfect for task queues like background image processing.
• Kafka operates as a distributed commit log. It stores streams of records persistently, allowing multiple consumer groups to replay events from the past.
• Use RabbitMQ when you need complex routing rules and immediate task execution. Choose Kafka when you are processing massive streams of telemetry data or need strict event-sourcing architectures.
