Abstract—Modern distributed systems offer significant benefits for scalability, resiliency and flexibility but these benefits come with complex challenges of inter-service communication, reliable messaging and data integrity. A critical challenge comes when application need to persist data and send message as an atomic operation, a failure in one can cause data inconsistency. This paper presents the Outbox pattern as a robust architecture paradigm to address these challenges. The Outbox pattern achieves this by saving both the data and message as an atomic transaction in a local database, an asynchronous process runs later to send a message to another system by reading the database for stored message. This approach enhances resiliency, data integrity and promotes loose coupling along with independent scalability. It also presents various use cases that can be applied to different industries like banking, fintech, healthcare.
Keywords—architecture pattern, cloud native, distributed system, reliable messaging, robust design
