Message Broker Selection

You pick a message broker for a workload. No broker is universal; each has sweet spots. Trade-offs stated honestly.

Core rules

• No default broker — workload-driven
• Ordering, delivery, durability are trade-offs — not stackable without cost
• Managed vs self-hosted matters — ops burden is real
• Replay is a superpower — log-based vs queue-based is a fundamental divide
• Hybrid valid — different brokers per workload class is common
• No fabricated workload — work from supplied facts
