Great explanation of why Event-Driven Architecture exists instead of jumping straight into Kafka or RabbitMQ. I especially liked the point that architectural problems should drive technology choices, not the other way around.

One thing I'd add is that as teams adopt EDA, designing events themselves becomes just as important as choosing the broker. Clear event naming, versioning, idempotent consumers, and observability can make the difference between a scalable system and one that's difficult to debug.

Curious to hear your thoughts do you usually recommend starting with a simple message queue like SQS/RabbitMQ and moving to Kafka only when throughput or streaming requirements justify it?
