Utility Server VIP and FQDN in AWS cluster deployments

Last Updated : Jun 10, 2026 |

In AWS cluster deployments, the Utility Server VIP is assigned to the eth1 interface. To find this VIP address, in the AWS Management Console, navigate to EC2 > Instances > <node name> > Network interfaces > eth1.

Unlike VMware and ASP deployments, where the Utility Server VIP and FQDN remain the same across the cluster nodes, AWS deployments have a dedicated set of Utility Server VIPs and FQDNs. That is why AWS deployments use a separate eth1 network interface.

In AWS deployments, the Utility Server FQDNs uses the following pattern:

<Utility Server Host Name><node number reduced by one>.<Domain Name>

For example, in a cluster with two nodes, where the Utility Server with the aads716–us host name is added to the avaya.in domain, the Utility Server FQDNs will be the following:

  • aads716–us0.avaya.in for the first, that is, the seed node in the cluster.

  • aads716–us1.avaya.in for the second node in the cluster.
