Failover Latency

Failover latency is the duration of time it takes for a redundant system to detect a failure and assume control of operations. In high-performance trading, this duration must be kept to an absolute minimum to prevent gaps in price discovery or missed trade opportunities.

High failover latency can lead to significant slippage or even total system stalls during periods of high market activity. Minimizing this metric requires optimized heartbeat monitoring and automated failover protocols that can trigger in milliseconds.

Architects focus on reducing the overhead of switching network routes and state transitions to ensure that the user experience remains smooth. It is a critical performance indicator for any platform managing live financial positions.
