It uses a typical setup for application servers providing services into the Internet. The the systems with the application server are protected by implementing a demilitarized zpnme (DMZ), which suppresses direct access from the Internet completely and allowing only well controlled accesses to the servers via the proxy. The entire environment was set up with z/VM guests on z/VM 5.2.

Through the project, we gathered experience on how to analyze and tune a cluster environment on Linux on IBM System z using the Trade 6.0 (Trade) application. We also learned where some of the pitfalls can be found. We were trying to find the best configuration to achieve the highest throughput.
