LANSA Web supports both Single-tier and Multi-tier installations.
A Single-tier installation includes the Web Server and Data/Application Server on a single machine. Deploying a WAM on a single tier machine is relatively straight forward.
A Multi-tier installation has the Web Server on one machine and the Data/Application Server on a separate machine. If you install a Multi-tier configuration with a Windows IIS web server, the XSL Processing of your WAMs, by default, is moved to the Web Server tier, thereby distributing the processing load across the tiers. The application on each machine needs to be deployed, then the machines connected as a separate step. This option is configurable in Web Administrator, Local Configuration of your LANSA Web Server Extension.
For details, refer to Linking Steps for Windows Multi-tier Set Up in the Web Administration Guide.
