1.6.1 Considerations for Multi Tier Deployment Models

Multi-Tier Deployment Model

With this model, if you will be using, for example, a Windows, IBM i or Linux Web Server with a Windows Application Data Server:

  • The Visual LANSA development environment is installed on the Data/Application Server. The LANSA Repository (including the generated HTML) and your application data are installed on this machine. 
  • The LANSA for the Web PC-based Administrator will only need to connect to the Data/Application Server.
  • A Visual LANSA system is not required on the Windows Web Server. Only the appropriate LANSA for the Web Plug-in needs to be installed on the Web Server.
  • A Windows Web Server will use the LANSA IIS Plug-in
  • An IBM i or Linux Web Server will use the LANSA Apache Plug in.

Mixed Multi-Tier Deployment Model

In this model, and assuming, for example, that you are using a Windows Web Server with an IBM i Application Data Server:

  • The LANSA for the Web development environment is installed on the Data/Application Server along with LANSA for i. The LANSA Repository (including the generated HTML) and your application data are installed on the Data/Application Server.
  • The LANSA for the Web PC-based Administrator will only need to connect to the Data/Application Server.
  • A Visual LANSA system is not required on the Web Server. Only the LANSA IIS Plug-in needs to be installed on the Web Server.
  • A Windows Web Server will use the LANSA IIS Plug-in
  • A Linux or IBM i Web Server will use the LANSA Apache Plug in.
  • A Listener must be configured on an IBM i Data/Application Server for the communications link from a Windows Web Server.
  • Refer to the LANSA for the Web Administrators Guide for set up instructions for Multi-Tier Deployment.
