Daily Term: Fault Tolerance

Fault Tolerance

Fault Tolerance is a system’s ability to continue functioning despite failures, such as hardware crashes or network issues. For example, a distributed database might use replication and leader election to ensure operations continue if a node fails. Fault tolerance improves reliability and availability, often through redundancy and failover mechanisms, but it increases complexity and resource usage, requiring careful design to balance cost and resilience.
