Using the Web Server Plug-in to load balance HTTP Requests to WebLogic cluster

The WebLogic cluster itself does not distribute the incoming HTTP requests across the Managed Servers, so the architecture design should foresee a load balance mechanism.

WebLogic can use either an external load balancer appliance/hardware such as the BIG-IP F5 (http://www.f5.com/products/big-ip), a Web Server such as the Apache HTTP Server configured with the WebLogic Web Server plug-in, or the embedded WebLogic HttpClusterServlet configuration.

Load balancing options:

  • External load balancer

  • Web Server with plug-in

  • WebLogic HttpClusterServlet configuration

For production environments, it is recommended to use a mixed architecture that includes an external load balancer and a Web Server with the proxy plug-in. The HTTP requests will be received and distributed by the external load balancer to the Web Servers, and the Web Servers will then proxy the requests through the plug-in across the WebLogic Managed Servers of...
