Digital Router Question:

Virtual Machines have only recently come into mainstream use, however they have been around under many different names for a long time. With the massive growth of hardware outstripping software requirements, it is now possible to have a server lying dormant 90% of the time while having other older systems at max capacity. Virtualizing those systems would allow the older operating systems to be copied completely and running alongside the server operating system- allowing the use of the newer more reliable hardware without losing any information on the legacy systems. On top of this, it allows for much easier backup solutions as everything is on a single server.
