DR from on-premises to AWS - Windows

InfoScale Enterprise lets you use the global cluster option (GCO) for DR configurations. You can use a DR configuration to fail over applications from on-premise cluster to AWS.

The following information is required:

VPN tunnel information between regions or VPCs
The Virtual private IP address to be used for cross-cluster communication.

Note:

If you use an Amazon VPN tunnel in a global cluster configuration between an on-premises site and AWS, the cluster nodes in the cloud must be in the same subnet.

Sample configuration for DR across regions or VPCs

The following graphic depicts a sample DR configuration from on-premise cluster to AWS cloud:

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 virtual private cloud, VPC, is configured in Region Aof the AWS cloud
- The same application is configured for HA on Node 3 and Node 4, which exist in the same subnet

Sample service group configuration for GCO from on-premise to cloud

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