In his Virtualization Blog this week, David Marshall from Infoworld mentioned a couple of recently published documents should make your reading lists. I have already talked about one of these in a previous post—“VI3 in a Cisco Network Environment.”
The other document David mentions is, “DMZ Virtualization with VMware Infrastructure.” This paper discusses the pros and cons and best practices associated with three different approaches to virtualized DMZs, right down to a fully collapsed model. It’s only six pages of text with liberal use of diagrams. I highly recommend giving it a read.
