Redundancy
Duplicating critical components of an automation system so that if one fails, another takes over. Example: two n8n instances running in active-passive mode if the primary fails, the secondary takes over within seconds.
Expert insight
Redundancy (running a backup system or process ready to take over) only provides real protection if it's actually tested under failure conditions, a backup automation path that has never been exercised is an assumption, not a verified safeguard, the same principle as failover, redundancy that's never tested is not proven redundancy.
In a real workflow
Critical webhooks are received by two independent endpoints, so one failure does not lose orders.
Common mistakes
- Redundant systems that share the same weak point.
- Never testing the redundant path.
Complexity level
Requires some familiarity with automation concepts.
