Failover definition

Failover is the ability of a computer system to automatically switch to a reliable backup system when it experiences network or service failure. When a primary system or one of its components fails, failover enables it to get back up and running immediately by switching to a redundant or standby system, server, or hardware device. That way, the services that the primary system offers will always be online and won’t be affected by the failure. This is a great solution for systems and networks that experience regular crashes and disconnects. It also allows the users of those services to get an uninterrupted experience.
