The Real Truth About Event-Driven Architecture

Despite all the hype, Event-Driven Architecture isn’t a magical cure-all. While it does help you decouple services at runtime, you can still end up with tight design-time coupling, swapped-out bottlenecks, and hidden complexities if you try to stretch it into every corner of your system. Complex workflows stitched together by events often turn into a maintenance nightmare rather than a clean, scalable solution.

Scalability in EDA simply shifts resource constraints instead of eliminating them—so be ready to tackle new chokepoints. Event ordering and sensible service boundaries matter way more than buzzwords. Focus on clear ownership of data, sane workflow granularity, and well-defined boundaries to make EDA actually work for you.
