What is difference between fault tolerance and fault resilience?

I am reading Spring Cloud and NetFlix APIs. Many places, I read Fault Tolerance and Fault Resilience keyword.

Please explain the difference.

Solution

  • The Fault Tolerant means the ability of an architecture to survive (tolerate) when an environment misbehaves by taking corrective actions, e.g, surviving a server crash or preventing a misbehaving API from bringing down the whole system, etc. The Fault Resilience is probably the capacity to recover from these type of scenarios quickly.

    After further reading of Netflix blogs and wikis, it seemed the terms Fault Resilience and Fault Tolerant were used interchangeably.
