Cloud Architect

When should cloud architectures use queues, pub/sub, or event streams?
Answer
Use messaging to decouple services and handle spikes.
- Queues: work distribution
- Pub/Sub: fan-out notifications
- Streams: immutable event logs
Key concerns: delivery semantics, ordering, retries, DLQs, and observability. Design consumers to be idempotent.
