How we saved an airport from a domino effect
At AeroPort, we set up fault isolation so that if one of 20+ microfrontends goes down, it doesn’t take the entire display board with it. Now each module follows a simple rule: if it falls, it shouldn’t take others down with it.

In AeroPort, we set up fault isolation so that a failure in one of the 20+ microfrontends wouldn’t bring down the entire display board. Because, let’s be honest, if the commercial zones module breaks, passengers still need to see flight information rather than get an unexpected digital detox in the terminal.
What we implemented:
- Error Boundaries — catch rendering errors inside a specific microfrontend without letting them pull down neighboring ones
- Circuit Breaker — stops cascading failures when backend services start failing
In practice, each module lives by the rule: if it falls, it shouldn’t take others down with it. In an era when distributed systems are back in the spotlight, this kind of isolation is no longer a “nice to have” — it’s a must. Especially in an airport, where uptime matters more than any flashy duty free banner.
