The Outbox pattern atomically saves domain events to an 'outbox' DB table in the same transaction as business data — a relay then publishes to the message broker, preventing lost events.

Diagram: Apache Kafka Apache Kafka
A distributed event streaming platform — topics, partitions, and consumer groups enable high-throughput, fault-tolerant, replayable message streams at massive scale.

Diagram: RabbitMQ RabbitMQ PHP 7.0+
A message broker implementing AMQP — producers publish to exchanges, exchanges route to queues, consumers pull from queues — providing durable, reliable message delivery.
