Virtualisation of interfaces between systems and entities will actually provide more robust and persistent characteristics of nodes and resources. It will also allow for dynamic and non-disruptive "adds, moves and changes", but will be a troubleshooting nightmare whereupon convergence of skills and depth of code shall introduce more complexity. A new paradigm of defensible, self monitoring and self diagnosing code will be required. I also believe we need a virtual internet for testing, but that's going to be the next big thing! Donal.
Note: EHV = End Host Virtualiser
NPV/NPIV = N_Port Virtualisation / N_Port Identifier Virtualisation
This is a pretty good overview on "
