Failover across AWS subnets using overlay IP - Windows
InfoScale clusters let you fail over IPs - and thereby, the application configured for HA - between different subnets in the same AZ or in different AZs.
The following information is required:
The overlay IP address to be used for failover
The device to which the IP should be plumbed
The directory in which the AWS CLI is installed; this input is not required if it is provided in the PATH environment variable
AWS does not allow the private IP of one subnet to be failed over to a different subnet. To overcome this limitation, provides an overlay IP, which is defined at the VPC level, so that it can be used across subnets.
The following graphic depicts a sample failover configuration across subnets within the same AZ using an overlay IP:
The sample configuration includes the following elements:
A virtual private cloud (VPC) is configured in Region A of the AWS cloud.
An application is configured for HA using an InfoScale cluster that comprises two nodes, Node 1 and Node 2, which are EC2 instances.
Node 1 exists in Subnet 1 and Node 2 exists in Subnet 2.
An overlay IP is configured, which allows the private IP of a node to be failed over from one subnet to another in an AZ as part of the failover or the failback operations.
