Description: Instance failover is a critical process in database management that allows service continuity in the event of failures in the primary instance. This mechanism is automatically triggered when a failure is detected, redirecting operations to a backup instance. Failover ensures that applications and users can continue accessing data without significant interruptions, which is essential for maintaining availability and data integrity. This process relies on data replication and constant synchronization between the primary and backup instances, ensuring that information is up-to-date and ready for use in case of a failure. Additionally, failover can be configured to be manual or automatic, depending on the specific needs of the organization and the criticality of the applications relying on the database. In a business environment, where downtime can translate into significant economic losses, instance failover becomes an indispensable tool for risk management and business continuity.
