Integration Patterns and Messaging Systems Questions

Understand approaches to integrating different systems: synchronous APIs, asynchronous messaging (queues, topics, events), batch processing, and data synchronization. Know when to use message queues vs. publish-subscribe vs. event streams. Understand the reliability patterns (acknowledgments, retries, dead-letter queues) and consistency implications. Know about API gateways, service discovery, and orchestration. Discuss trade-offs between tight coupling and loose coupling, and how integration choices affect system resilience.
