It's perhaps worth noting that any example of IaaS (Infrastructure As A
Service) deals with the same issues that Kelly will be dealing with.
This is typical of "cloud" computing; in fact, Amazon EC2 is perhaps the
largest public cloud provider, and any firewalls, A-V scanners, IDS
engines and other security-related pieces of infrastructure are running
in VMs, whether that's immediately evident to the end user or not.
(Linux-based EC2 instances are all, AFAIK, Xen DomU instances. I
suspect Windows EC2 instances also run under Xen, but I've never
researched that.)
So, at the very least, a whole bunch of quite large companies have
decided that yes, it *is* OK to host security services on virtualized
hardware.
By the same token, I'm quite certain that Citrix provides a *very*
different level of support to Amazon than they'll provide to you or me!
