Deployment diagram for my assignment is almost similar to Cade's example. But only addition to it is to add firewall. The whole application is packaged in a single ear file and is expected to have heavy traffic.
Diagram is almost similar to Cade's example and ear file is shown as artifact in web and app server profile. In Load balancer I am planning to include even firewall, mentioning it has load balancer with firewall.
It is expected to be implemented using DMZ, In notes if I mention that load balancer is in DMZ used as reverse proxy to server static pages and Cluster is behind DMZ, Is it ok to show like this or I need to put even the whole DMZ in the diagram.
