Enterprise Message Queue Architecture: A Design Checklist for Asynchronous Decoupling and Reliable Delivery
Message queues can absorb traffic spikes, isolate services, and support asynchronous workflows, but they also introduce challenges involving duplicate delivery, ordering, retries, backlogs, and observability. Using work queues, publish-subscribe, routing, and event streaming as a framework, this article covers requirements analysis, message contracts, idempotent processing, failure isolation, capacity, and access control. It helps enterprises select patterns that fit their workloads and establish operable standards for reliable delivery with clear service ownership.
