Web Tier

If you use the internal Web server provided with PPM, there is no need to configure it. However, if you must use an external Web server because of firewall requirements, single sign-on (SSO), or Web tier clustering, then follow the configuration recommendations described in External web server configuration.

If redundancy is required at the Web tier, then you must use a hardware or software load balancer to distribute incoming traffic. You can use a hardware load balancer in the absence of a separate PPM Web tier if SSO or other requirements do necessitate the Web server.
