Failovertilanteista

Failovertilanteista refers to situations where a primary system or component fails and a secondary, backup system automatically takes over to maintain service continuity. This is a crucial aspect of high availability and disaster recovery strategies in IT infrastructure. The primary goal of failover is to minimize downtime and data loss when a failure occurs.

There are several types of failover, including active-passive and active-active configurations. In an active-passive setup, the secondary system remains idle until the primary fails, at which point it becomes active. In an active-active setup, both systems are operational simultaneously, sharing the workload, which can provide faster failover and improved performance. Failover can be triggered by various events such as hardware malfunctions, software errors, network disruptions, or power outages.

The process typically involves monitoring the health of the primary system. If predefined thresholds indicating failure are met, a failover mechanism initiates the switch to the secondary system. This often includes redirecting network traffic and ensuring data consistency between the systems. Testing failover procedures regularly is essential to ensure they function as expected during a real incident. Successful failover minimizes disruption to users and business operations.
