DR across GCP regions or VPC networks - Windows

InfoScale Enterprise 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 VPC networks in GCP. The cluster nodes can be in the same zone or in different zones.

The following graphic depicts a sample DR configuration across GCP regions:

The following snippet is a service group configuration from a sample VCS configuration file (main.cf) at the primary site (Region A):
