Creating load balancers

Last Updated : Jun 05, 2026 |

About this task

In a cluster deployment, a load balancer distributes incoming traffic between Avaya Aura® Device Services nodes. In Google Cloud Platform cluster deployments, you must create and configure a separate load balancer for each VPC network:

  • A load balancer for a VPC network that contains application network interfaces of the Avaya Aura® Device Services application. These network interfaces are the NIC0 interfaces of virtual machines.

  • A load balancer for a VPC network that contains network interfaces of the Utility Server nodes. These network interfaces are the NIC1 interfaces of virtual machines.

Before you begin

Configure instance groups for your deployment as described in Creating an instance group for load balancers.

Procedure

Repeat the following steps to create a load balancer for Avaya Aura® Device Services nodes and for Utility Server nodes.

  1. In Google Cloud Console, navigate to Network services > Load Balancing.
  2. Click Create load balancer.
  3. Select TCP Load Balancing.
  4. In Internet facing or internal only, select Only between my VMs and then click Continue.
  5. In Name, type a name of your choice for the load balancer.
  6. Click Backend configuration and configure the following settings:
  7. In Region, select a region where you want to create the load balancer.
  8. In Network, select a VPC network depending on the load balancer that you are configuring:

    • For the load balancer for the VPC network that contains Avaya Aura® Device Services application network interfaces, select the VPC network that contains NIC0 network interfaces of the virtual machines.

    • For the load balancer for the VPC network that contains Utility Server network interfaces, select the VPC network that contains NIC1 network interfaces of the virtual machines.

  9. In Instance group, select the instance group that you created previously.
  10. In Health check, in the drop-down list, click Create another health check and configure the following settings:
    1. In Name, type a name of your choice for the health check.
    2. In Protocol, select TCP.
    3. In Port, type 443.
    4. For other settings, keep the default values.
    5. Click Save and continue.
  11. In Health check, select the health check that you just created.
  12. In Session affinity, select Client IP and protocol.
  13. Click Frontend configuration

    Google Cloud Platform displays the Frontend configuration page.

  14. In Name, type a name of your choice for the frontend configuration.
  15. In Subnetwork, select the subnetwork where you deployed virtual machines.
  16. In the Internal IP section, in Purpose, select Non-shared.
  17. In the Internal IP section, in IP address, select Reserve static internal IP address and configure the following settings:
    1. In Name, type a name of your choice.
    2. In Static IP address, select Assign automatically.
    3. Click Reserve.
  18. In Ports, select Multiple.
  19. In Port number, type the following comma-separated port numbers:

    • For the load balancer for Avaya Aura® Device Services nodes, type 443,8440,8442,8443,8445.

    • For the load balancer for Utility Server nodes, type 80,8443,443.

  20. For other frontend settings, keep the default values.
  21. Click Done.
  22. Optional To verify the load balancer settings, click Review and finalize.
  23. Click Create.
  24. Repeat the procedure to create a load balancer for the Utility Server nodes.
