RabbitMQ wird für asynchrone, entkoppelte Kommunikation verwendet — häufige Anwendungsfälle sind Task/Job-Queues, Microservices-Messaging, Lastverteilung und verschiedene Messaging-Muster. Das Verständnis der Anwendungsfälle verdeutlicht, wo RabbitMQ passt.
Häufige Anwendungsfälle
✓ TASK / JOB QUEUES → offload time-consuming work to background workers (e.g. send emails,
process images, generate reports) → fast responses, async processing (the classic use)
✓ DECOUPLING microservices → services communicate via messages (independent, resilient)
✓ LOAD DISTRIBUTION → distribute tasks across multiple workers (competing consumers →
parallel processing, scaling)
✓ ASYNC workflows → coordinate steps in a process via messages
✓ PUB/SUB → broadcast events to multiple consumers (fanout)
✓ RPC / request-reply → request/response messaging between services
✓ Buffering / smoothing load → absorb spikes; workers process steadily
