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:
