The Real Truth About Event-Driven Architecture

Event-driven systems really can help you avoid tight design-time coupling, but don’t mistake them for a magic bullet—temporal coupling still bites you, scalability often just moves your bottleneck elsewhere, and wrestling with event ordering can get messy fast.

Beware building huge, cross-service workflows—those are a classic design smell. Instead, focus on clear service boundaries, know where and why you need events, and keep the complexity in check.
