Designing event-driven architectures with Anypoint MQ

Abstract integration diagram

Async workflows are easy to build and hard to debug. A few patterns keep event-driven systems on Anypoint MQ observable and recoverable instead of mysterious.

Design for the messages you will lose

Assume delivery will sometimes fail and sometimes duplicate. Idempotency keys make replays safe, and a sane dead-letter policy turns a silent failure into a visible queue you can act on.

For most teams, at least once delivery with idempotent consumers beats chasing exactly once. It is simpler to reason about and it fails in ways you can see.
