Creating an instance group for load balancers

Last Updated : Jun 10, 2026 |

About this task

An instance group is a collection of virtual machines that you can manage as a single entity. In a cluster deployment, you require an instance group to configure load balancers. You do not need an instance group in a standalone deployment.

If virtual machines in your deployment are located in multiple zones or regions, you must create a separate instance group for each specific zone or region.

For more information about instance groups, see Instance groups.

Before you begin

Deploy virtual machines as described in Virtual machine deployment checklist.

Important:

Do not install the Avaya Aura® Device Services application on the virtual machines until you configure instance groups and load balancers. If you install Avaya Aura® Device Services before configuring load balancers, then Avaya Aura® Device Services firewall rules might be configured incorrectly.

Procedure

  1. In the Google Cloud Console, navigate to Compute Engine > Instance groups.
  2. Click Create instance group.
  3. In the left area of the page, click New unmanaged instance group.
  4. In Name, type a name of your choice.
  5. In Location and Zone, select the location and zone where your virtual machines are located.
  6. In Network, select the VPC network that contains the primary nic0 network interfaces of your virtual machines.
  7. In Subnetwork, select the subnetwork where your virtual machines are deployed.
  8. In VM instances, click Add an instance and then select a virtual machine that you deployed.
    Note:

    The list only contains virtual machines deployed in the region and zone that you selected in step 5.

  9. Repeat the previous step to add other virtual machines in your deployment to the instance group.
  10. Click Create.
  11. If you have virtual machines located in other zones or regions, repeat the procedure for all these zones or regions.

Next Steps
