Sizing and capacity planning

WebSEAL provides an authentication and authorization mechanism based on Tivoli Access Manager. It enables an end-to-end Single Sign On (SSO) solution for secure transactions for WebSphere application servers.

Here WebSEAL is used as proxy inside a DMZ from a secure WebSphere Application server environment. Each server runs on virtual hardware under z/VM.

The paper describes how to setup the environment and how it performs in various scenarios. Additionally it shows the impressive advantage of the IBM system z cryptographic hardware features CPACF and CEX2C cards and how to setup the system to get cryptographic hardware support. It also demonstrates that the implementation of a DMZ with all its services and servers is a very good case for server consolidation on z/VM.
