Load Balancer

The edge gateway acts as a basic Layer 3 load balancer, and distributes IP traffic to a pool of servers while appearing as a single virtual server.

The offered load balancing methods are:

  • Roundrobin

  • IP hash

  • URI

  • HTTP header

  • Least connected

Note: The edge gateway Load Balancer meets basic requirements. To meet complex requirements, contact your sales representative for advanced solutions.

Configure a load balancer

To configure a load balancer:

  1. On the vCloud Directory Virtual Data-Center dashboard, select the VDC that contains the edge gateway where you will configure the load balancer.

  2. From the left navigation panel, click Edges.

  3. Choose the edge you want to configure and click Configure Services.

  4. Click the Load Balancer tab.

  5. Make sure the Enabled option is selected on the Global Configuration tab.

  6. Select Enable logging if you have a syslog server configured.

  7. Click Save changes.

Configure a pool server

Pool servers are the real servers that will be masked by the load balancer.

Note: Before configuring a pool server, make a list of the IP addresses that you will use to populate the pool, later in the procedure.

  1. Click the Pools tab.

  2. Click the add, button.

  3. In the Add Pool window, enter a Name and Description.

    4. Note: The pool name should not include any spaces.

  5. From the Monitors dropdown, select the monitors policy.

  6. Enable the Transparent option for the IP addresses to be transparent.

  7. In the Members section, click the add,button.

  8. In the Add Member window, enter the server Name, IP Address, Port, and Weight.

  9. Click Keep.

  10. To view the status of pool members, click Show Pool Statistics.

Configure a virtual server

A virtual server masks the pool of real servers and presents a single IP address.

  1. Click the Virtual Servers tab.

  2. Click the add, button.

  3. In the Add Virtual Server window, enable the option to Enable Virtual Server.

  4. Enter a Name for the virtual server, assign it a virtual IP Address, and assign it to the server Pool you want to mask.

    You can also choose the services you want to apply to the virtual server.

  5. Click Keep.
