Failover

What is a failover?

Failover refers to a mechanism in which a system automatically switches to a backup system or redundancy solution in the event of a failure in order to maintain operations. Failover solutions ensure high availability and reliability in IT infrastructures, especially in critical applications such as banking systems, e-commerce platforms and medical systems.

Advantages and application examples

Failover prevents business interruptions, minimizes downtimes and protects companies from financial losses due to system failures. Typical applications include cluster systems, where several servers work in parallel, and database mirroring. Failover solutions are a central component of disaster recovery plans and ensure that IT services remain available even in an emergency.
