What Is Failover?

What you have here is a classic bromance: you love and hate him, yet you will always care for him as he is always there for you. This kind of relationship always seems to be too perfect to be true. Yet here we are to tell you more about it. Failover is like a friend who's always there for you but makes you feel like a loser because he's so darn perfect. You know what we are talking about: that friend who's always there for you no matter what but makes you feel like a loser because they're just so darn perfect. You know, the one who will be there for you no matter what and make sure that everything goes smoothly but also makes you feel like a loser because they're just so darn perfect? Yeah, that's a failover. A failover is a backup constantly ready to switch to a highly reliable system. It is continuously prepared to switch to a highly reliable backup in a redundant manner or an operational standby mode upon the failure of a primary server, application, system, or another primary system component. Failover is a term used to describe how a system reacts when it encounters failure. It's also known as fallover, which is probably why you've never heard of it. The system automatically switches to a backup resource when a failover occurs to avoid any service disruption. This is done using redundancy or high-availability features, such as RAID technology or load balancing. Failover can be either manual or automatic. Manual failover occurs when network administrators manually change a server's or network device's configuration to make it function again after an outage. Automatic failover occurs when the backup component takes over without user intervention. In other words, no one has to do anything except watch helplessly.
