Scenario 2: IBM WebSphere Application Server with IBM HTTP server transport

An overview of the setup for scenario 2.

Figure 1 shows the System Under Test (SUT) system and software setup with IBM HTTP server (IHS)acting as HTTP transport for IBM WebSphere Application Server (WAS).

Basically, this second scenario is set up in the same way as the previous scenario. It implements also a three-tier architecture, consisting of a client, an application server and a database server. The only difference is that WAS is not responsible for HTTP transport. The HTTP transport is now offloaded to the IHS. However the additional web server processes are running in the same Linux™ server as the WAS.
