DR from on-premises to Azure and across Azure regions or VNets - Windows

VCS lets you use the global cluster option (GCO) for DR configurations. You can use a DR configuration to fail over applications across different regions or VNets in Azure or between an on-premises site and Azure.

The following is required for on-premise to cloud DR using VPN tunneling:

The following is required for region to region DR using VNet peering:

The sample configuration includes the following elements:

The following snippet is a service group configuration from a sample configuration file (main.cf):
