SDDC Manager orchestrates the deployment, configuration, and (LCM) of vCenter, NSX, and vRealize Suite above the ESXi and vSAN layers of VxRail. It unifies multiple VxRail clusters as workload domains (WLDs) or as multiple WLD. For multiple-availability zones (Multi-AZs), SDDC Manager creates the stretched cluster configuration for a dual-availability zone (AZ) WLD.
