DR across GCP regions or VPC networks - Linux
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 the Google Cloud. The cluster nodes can be in the same zone or in different zones.
The following information is required:
VPC peering between regions or VPC networks
The IP address to be used for cross-cluster communication:
Virtual private IP for cluster the nodes that exist in the same subnet
Overlay IP for cluster the nodes that exist in different subnets
The
google-api-python-clientGCP Python module. For details, see the Bundled Agents Reference Guide - Linux.
The following graphic depicts a sample DR configuration across GCP regions:
The sample configuration includes the following elements:
VPC network peering between Region A and Region B
The primary site has the following elements:
A VPC network, VPC1, is configured in Region A of the Google cloud.
An application is configured for HA using an InfoScale cluster that comprises two nodes, Node 1 and Node 2, which are VM instances.
Node 1 exists in Subnet 1 and Node 2 exists in Subnet 2.
The virtual private IP of a node to be failed over in a subnet within the same zone or across zones.
The secondary site has the following elements:
A VPC network, VPC2, is configured in Region B of the Google cloud.
The same application is configured for HA on Node 3 and Node 4, which exist in Subnet 3 and Subnet 4 respectively.
The virtual private IP of a node to be failed over in a subnet within the same zone or across zones.
