What is Failover?
Failover is the ability to switch to another communication channel in cases where the primary communication channel fails to deliver a message.
Failovers can be considered as backup or standby channels.
How does Failover work?
Failovers occur automatically after a certain amount of time when a system detects that a message was not delivered via the primary source of communication. They ensure that you can get your messages delivered via an alternative means of contact.
What is the difference between Failover and Backup?
Backups are copies of existing systems or data stored for later recovery. Failover is a backup connection or duplicate of the production server environment when the main one does not work unexpectedly.
What is the difference between Failover and Disaster Recovery?
Failover and disaster recovery ensure high availability and business continuity. Still, failover is more relevant to day-to-day small-scale machine or network failures, while disaster recovery addresses large-scale infrastructure damage.
