Really enjoyed this post. Event-driven systems always look elegant on paper, but in practice the interesting part is how they behave under load, especially when multiple services, queues, and async steps all start interacting at once. I like that you focused on the load testing angle instead of only talking about the architecture itself, because that’s where real confidence in a system actually comes from.

In my own DevOps and cloud work, I’ve seen how important it is to test not just the happy path but also throughput, backpressure, retries, and failure handling in distributed systems. Once you move into event-driven designs, observability and timing become just as important as the code itself. A setup can look clean in the diagram, but the real story shows up when you push it under realistic traffic.

This was a solid write-up and a good reminder that performance testing is not just about finding bottlenecks — it’s about understanding the behavior of the whole system under stress.
