The Real Truth About Event-Driven Architecture

Event-Driven Architecture promises loose coupling and easy scaling, but in reality you’re trading one set of bottlenecks for another—temporal coupling (when events fire) can be just as sticky as design-time dependencies. Piling on more nodes doesn’t magically solve hot spots; it just moves them around.

On top of that, stitching together complex workflows across services quickly turns into a tangled mess—if you find yourself orchestrating every step in code, you’ve lost the simplicity you were chasing. Lastly, unless you’re deliberate about event ordering and well-defined service boundaries, you’ll end up with hard-to-debug chaos rather than clean, decoupled streams.
