We have a private bay in which we built a private cloud with vmware vSphere. We received directly the web trafic on a firewall VM and then we forward the trafic to the appropriate VMs.
We are worry about this situation because the first machine direcly exposed to the web is the vmware hyperterminal. Is this a common and safe architecture? Is it better to do this kind of architecture or to put the firewall on a dedicated server?
