Why Your Microservices Architecture Is a Ticking Time Bomb
“Let’s break this monolith into microservices!”
It’s the rallying cry of architects and CTOs everywhere. Microservices architecture has been praised as the solution to scaling problems, team autonomy, and deployment flexibility. Major tech companies showcase their microservices success stories, and suddenly every startup thinks they need 50 independently deployable services to be competitive.
After spending years helping companies untangle their microservices disasters, I can tell you that for many organizations, their beautifully designed microservices architecture is quietly evolving into a catastrophe waiting to happen.
Here’s why your microservices might be a ticking time bomb — and what you can do to defuse it before it explodes.
The Distributed Monolith: Worst of Both Worlds
The most dangerous type of microservices architecture isn’t actually microservices at all — it’s what we call a “distributed monolith.”

- You can’t deploy one service without deploying others
- Services directly call each other via synchronous HTTP/gRPC
- Schema changes in one service break multiple other services
- You have circular dependencies between services
- Your services share a database or access each other’s databases
- Seemingly simple features require coordinating multiple service teams
A distributed monolith combines the tight coupling of a monolith with the operational complexity of microservices — giving you the drawbacks of both with the benefits of neither.
The Cascading Failure Nightmare
One of the most insidious problems with poorly designed microservices is how failures propagate through the…
