The failover strategy is a critical component of ensuring high availability and reliability in system design and operations. It involves the automatic switching to a standby system when the primary system fails or becomes unavailable. This process helps ensure that services continue to run without significant downtime, thereby maintaining business continuity and minimizing disruptions.

In a failover scenario, if the primary system encounters an issue—such as hardware failure, software malfunction, or network problems—the system automatically transfers control to a backup or standby system. This seamless transition allows users to experience minimal interruption, as the standby system takes over the operations that the primary system was handling. This approach enhances the resilience of IT systems and applications, making it a fundamental practice in cloud environments and other IT infrastructures.
