The Real Truth About Event-Driven Architecture

Event-Driven Architecture often gets hyped as the silver bullet for loose coupling and infinite scalability, but there’s more nuance here. You’ve got temporal vs. design-time coupling to watch out for, and scaling your events doesn’t magically solve every bottleneck—it can just move them around. Plus, stitching together complex workflows across multiple services usually signals a design smell, not a clever pattern.

Beyond that, nailing event ordering and defining clear service boundaries are where the real magic (and headaches) lie. Get those right, and you’ll tame the chaos of asynchronous systems; get them wrong, and you’ll be chasing ghosts in your logs.
