I'm considering having an HTTP server as a reverse proxy between the clients and the cluster of application servers.
This will require off-course a DMZ zone in witch this reverse proxy will sit.

My question is: how do I depict this DMZ on the deployment diagram?

I was thinking to add an artifact named <<firewall>>, on the the physical machine of the reverse proxy. But then where do I put the second firewall?

Or perhaps what I need are two more physical machines to install the firewall software on them? In this case I will finish having a deployment topology quite stuffed with servers:
2 for firewalls, 1 for reverse proxy, 2 for clustered application servers and perhaps one more for the Message Broker.

Is the price of the solution an issue I need to consider?
