Application Integration Patterns for Microservices
summary
Compares concrete messaging patterns for microservices and shows when they beat REST by quantifying tradeoffs: uses publish–subscribe and point-to-point channels (topics vs queues), durable subscriptions and message persistence to buffer spikes, and standard protocols like JMS/MQ for interoperability. Explains delivery semantics — at-least-once delivery vs best-effort — and why exactly-once is usually infeasible, demonstrates the saga pattern and state-machine implementations for multi-step transactions, and shows buffering/consumer scaling working to absorb millions of requests.
