Reliability vs Fault Tolerance
I am confused with the following terms: Reliability and Fault Tolerance According to Designing Data Intensive Applications book, the definition of Reliability is: The system should continue to work correctly (performing the correct function at the desired level of performance) even in the face of adversity (hardware or software faults, and even human error). And from what I understand, Fault Tolerance means the ability of a system to keep functioning despite the occurrence of a fault. So is fault tolerance a necessary condition for reliability OR is it a necessary and sufficient condition for reliability. Would be great if someone could explain with a practical example. Thanks in advance.
