Failover vs. Failback
⋙ Failover is switching the running application to another Availability Zone, or even a different Region, should outages or issues occur that threaten the availability of the application.
⋘ Failback is the process of returning the application to the original on-premises location or Region. For failovers to another Availability Zone, customers who are agnostic to the zone may continue running the application in its new zone indefinitely if so required. In this case, they will reverse the recovery replication, so the recovered instance is protected for future recovery. However, if the failover was to a different Region, its likely customers will want to eventually fail back and return to the original Region when the issues that caused failover have been resolved.
