 Site Recovery service contributes to your business continuity and disaster recovery (BCDR) strategy by keeping your business apps up and running, during planned and unplanned outages. Site Recovery manages and orchestrates disaster recovery of on-premises machines and Azure virtual machines, including replication, failover, and failback. In the case of Azure virtual machines, Site Recovery helps with replication, failover, and failback between two Azure regions. It is the recommended Disaster Recovery option to keep your applications up and running in the event of regional outages. It also helps address the compliance needs of your organization when it comes to resiliency against different types of failures.

These customers are aware of and acknowledge the fact that metro Disaster Recovery strategy may not work in case of a large-scale physical disaster and accept this risk. For such customers, Zone to Zone Disaster Recovery can be used as a Disaster Recovery option.

 2. Many other customers have complicated networking infrastructure and do not wish to recreate it in a secondary region due to the associated cost and complexity. Zone to Zone Disaster Recovery reduces complexity as it leverages redundant networking concepts across Availability Zones making configuration much simpler. Such customers prefer simplicity and can also use Availability Zones for Disaster Recovery.
