Announcing public preview of Azure IoT Hub manual failover feature – IoT Hub cloud service manual failover enables customers to failover an IoT hub instance from its primary Azure region to its corresponding geo-paired region with a recovery time objective (RTO) of 10 min–2 hours. The IoT Hub service provides cross-regional automatic disaster recovery as a default mitigation for region-wide failures or extenuated outages, which has an RTO of 2 – 26 hours. If your business uptime goals are not satisfied by the RTO that the Microsoft-initiated failover provides, you should consider using manual failover to trigger the failover process yourself.
