Description: Host failover is a critical process in network and computer system management that allows for automatic transition to a backup host in the event that the primary host fails. This mechanism is essential for ensuring high availability and service continuity, minimizing downtime, and ensuring that applications and services continue to operate without interruption. In the context of network routing protocols, failover is implemented to redirect traffic through alternative routes when a link or node becomes inoperative. In virtualization environments, this technique is used to maintain the operability of virtual machines, allowing workloads to be transferred to backup hosts in the event of hardware or software failures. Host failover not only enhances the resilience of IT infrastructure but also optimizes resource management, enabling organizations to respond quickly to incidents and maintain end-user satisfaction.
