Failover within an Azure subnet using private IP - Windows
InfoScale clusters let you fail over IPs - and thereby, the application configured for HA - within the same subnet in the same VNet.
The following information is required:
A private IP (secondary private IP) address to be failed over
The device to which the IP should be plumbed
The following graphic depicts a sample failover configuration within the same subnet using a private IP:
The sample configuration includes the following elements:
A Azure virtual network (VNet) is configured in Region A of the Azure cloud
An application is configured for HA using a cluster that comprises two nodes, Node1 and Node2, which are Azure virtual machines
Both the cluster nodes exist in the same subnet
A private IP is configured, which is failed over from one node to the other as part of the failover or the failback operations
The following snippet is a service group configuration from a sample configuration file (main.cf):

SystemList = { AzureVM1 = 0, AzureVM2 = 1 }
