Failover
Automatically switching to a backup when the main system fails
What's it for?
Keeps a service running by switching to a backup automatically when the main one fails.
For example…
When the primary database stops responding, failover automatically directs the application to its ready standby.
A website fails over to a second data centre after the first loses power, keeping the service available with minimal interruption
Think of it like…
A building switching to its backup generator when the mains power fails
