Step 4. Configure Load Balancing for Web Services

Step 4. Configure Load Balancing for Web Services

To run web service requests on a grid, you must configure an external HTTP load balancer. If you do not configure an external HTTP load balancer, the Data Integration Service runs the web service on the node that receives the request.
To configure load balancing, specify the logical URL for the load balancer in the Data Integration Service properties. Then, configure the external load balancer to distribute web service requests to all nodes in the grid that have both the service and compute roles.
  1. Complete the following steps in the
    Administrator tool
    to configure the Data Integration Service to communicate with the external HTTP load balancer:
    1. On the
      Services and Nodes
      view, select the Data Integration Service in the Domain Navigator.
    2. Select the
      Properties
      tab.
    3. In the
      Web Service Properties
      section, click
      Edit
      .
      The
      Edit Web Service Properties
      window appears.
    4. Enter the logical URL for the external HTTP load balancer, and then click
      OK
      .
  2. Configure the external load balancer to distribute requests to all nodes in the grid that have both the service and compute roles.
