What is the difference between High Availability and Fault Tolerance in AWS architecture?

Accepted Answer

High Availability in AWS architecture ensures a system is operational for a high percentage of time, tolerating brief interruptions for recovery. On the other hand, Fault Tolerance means a system continues operating without interruption even when component failures occur, typically requiring redundant systems running simultaneously.
