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:

Prepare the setup at on-premise data center
Prepare the setup at on-cloud data center
Establish a VPN tunnel from on-premise data center to cloud data center
Virtual private IP for cluster nodes that exist in the same subnet. The IP address is used for cross-cluster communication

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

Prepare the setup at both the data centers in the regions
Establish a VNet peering from one region to the other region
Virtual private IP for cluster nodes that exist in the same subnet. The IP address is used for cross-cluster communication

Note:

If you use an VPN tunnel between an on-premises site and Azure or you use VNet peering between Azure regions, the cluster nodes in the cloud must be in the same subnet.

Sample configuration with private IP

The sample configuration includes the following elements:

VPN tunnel between on-premise data center and Region A
The primary site has the following elements:
- Cluster nodes in the same subnet
- Virtual private IP for cross-cluster communication
The secondary site has the following elements:
- A VNet is configured in Region A of the Azure cloud
- The same application is configured for HA on Node 3 and Node 4, which exist in Subnet
- Virtual private IP for cross-cluster communication

Sample service group configuration with private IP

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