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.

Explain the difference between message queues and publish-subscribe (topics). Provide examples of real-world use cases where a queue is the better fit and where pub-sub is preferable. Include a short comparison of delivery semantics (e.g., competing consumers vs fan-out).

A downstream analytics job requires events in canonical form, but multiple upstream services emit different representations. As a Solutions Architect, how would you introduce a canonical data model and enforce it across pipelines while minimizing friction for teams?

A client asks how to expose an internal microservice functionality without giving direct network access to it. Propose an integration approach using API gateway, service mesh, or BFF patterns. Explain trade-offs in terms of security, caching, and developer velocity.

A partner asks for SLAs on message delivery including max time to delivery and guaranteed durability. How do you craft a realistic SLA for an asynchronous messaging integration, and what operational mechanisms back up the SLA (replication, ACKs, retries, monitoring)?

Describe how you'd implement end-to-end encryption and zero-trust networking for cross-organization event streams that traverse public clouds. Include key exchange, broker trust models, and approaches to prevent unauthorized consumers from replaying events.
