Fault Tolerance vs Redundancy: Complete Comparison | Vibepedia

Fault tolerance and redundancy are two related but distinct concepts in system design, with fault tolerance referring to a system's ability to continue functioning despite failures, and redundancy referring to the duplication of components to ensure continued operation. As noted by experts like Steve Jobs and Elon Musk, designing systems with these concepts in mind is crucial for ensuring reliability and minimizing downtime. For instance, companies like Google and Amazon have implemented fault-tolerant systems to ensure high availability, while NASA has used redundancy in its spacecraft systems to ensure mission success.
