The Best Damn Server Virtualization Book Period: Including Vmware, Xen, and Microsoft Virtual Server

Building a virtual server park on one machine is one step, creating an entire network infrastructure and logical dividing servers through virtual networks is another.
Using virtual networks opens the possibility to use Virtual Server in your test environment to include test/production scenarios with a demilitarized zone (DMZ). It is even possible to configure Virtual Server in such a way that network users aren t able to connect to the physical server over the network, enabling you to reduce the attack surface even further.
Each virtual machine can have up to four network adapters, each of which can be configured differently. A virtual network can be configured to support:
External resources A network that connects the virtual server and the virtual machines to outside resources such as the Internet or other resources on the local area network (LAN). This type of network uses the physical network adapter in the host computer for the virtual network.
Internal networks An internal network connecting virtual machines only to other virtual machines on the host computer or a connection between the virtual machine and the virtual server host computer. This type of network uses the Microsoft Loopback adapter and does not require any external support or physical network adapter.
Using the different types of virtual networks will enable you to build very sophisticated infrastructures without a large investment in physical servers or network devices. You can also use the features of the virtual network...
