A tenant administrator or business group manager can configure a load balancer for a multi-machine component blueprint. All machines provisioned from the component blueprint are added as members of the load balancer.

About this task

When you configure a load balancer, you specify a network adapter and select an external, private, NAT, or Routed network profile for the virtual IP address. The network profile you select for the virtual IP address must be the same one that the network adapter uses.

Prerequisites

Procedure

  1. Select Infrastructure > Blueprints > Blueprints.
  2. Locate a multi-machine blueprint with at least one virtual component blueprint.
  3. Click Edit in the drop-down menu.
  4. Click the Build Information tab.
  5. Locate a blueprint in the Components table that has editable network settings.

    Look for Edit in the Network column.

  6. Click the Load Balancer tab.
  7. Select the service to use for load balancing.

    The load balancer settings are not editable if a machine provisioned from this blueprint still exists.

    1. Select the service check box in the Services table.

      The service entry becomes editable.

    2. Type values in the text boxes as needed.

      vRealize Automation populates the text boxes with typical values.

    3. Click the Save icon (Save) to save the values and select the service.

      Selecting a service enables the text boxes for that service.

    4. (Optional) : Repeat to add other services.
  8. Type the URI in the URI for HTTP service text box, if enabled.

    For vCloud Networking and Security 5.5.2, do not leave this option blank even if disabled. Type / as the default value to avoid a load balancer data path error.

  9. Type the ID of the network adapter in the Network adapter text box, or use the up and down arrows to select a value.

    The ID is in the # column of the Network Adapters table on the Network tab. During provisioning, a load balancer pool member assumes the IP address of the network adapter.

  10. Select the network profile from the Network profile drop-down menu in the Virtual IP section.

    An external, private, or NAT network profile must have the load balancer virtual IP address in its IP range, static for external, static or DHCP for others. A routed network profile does not have a static IP range and does not have this requirement.

  11. For private and NAT network profiles, type the virtual IP address for the load balancer in the IP Address text box.

    The IP address must be within the IP ranges defined in the network profile.

  12. Click OK.
