The Real Truth About Event-Driven Architecture

Event-Driven Architecture (EDA) gets hyped as the silver bullet for loosely coupled, scalable systems—but it’s not a one-size-fits-all. Temporal coupling still hides at runtime even if you decouple design time, and scaling doesn’t magically dissolve bottlenecks, it just shifts them around. Chaining complex workflows across services often signals a design smell rather than a clever solution.

On top of that, event ordering adds extra wrinkles—without clear boundaries and a solid ordering strategy, you’ll end up with chaos instead of agility. EDA can shine when you embrace true decoupling, avoid hidden dependencies, and keep your event flows simple and well-ordered.
