In the physical network diagram, there is no virtualization platform set up. The network is set up with physical devices, such as firewalls, switches, servers, and full desktops. Each department has its own servers and network segments. A centralized management for the whole company does not exist. This is a costly solution due to all the physical hardware. If redundancy is a requirement, it will incur twice the cost since we will need identical physical servers. All the connectivity in this network is done with physical cable links. Backups in this setup are quite challenging since all the physical servers in the two departments have to be backed up on a per-device basis.
