 It should be noted that these types of failures, although rare, fall outside the scope of the protection offered by a stretched cluster private cloud. Because of those types of rare failures, a stretched cluster solution should be regarded as a multi-AZ high availability solution reliant upon vSphere HA. It's important you understand that a stretched cluster solution isn't meant to replace a comprehensive multi-region Disaster Recovery strategy that can be employed to ensure application availability. The reason is because a Disaster Recovery solution typically has separate management and control planes in separate Azure regions. Azure VMware Solution stretched clusters have a single management and control plane stretched across two availability zones within the same Azure region. For example, one vCenter Server, one NSX Manager cluster, one NSX Edge VM pair.
