This kind of msg aimed squarely at the PHB
"the OpEx nirvana of having one system administrator be able to manage 1,000 virtual nodes in a cluster all by his or her lonesome"
If I were proposing a real business case for Virtual Machines in the Cloud then I would describe the current infrastructure for a medium size business eg. switches, routers, servers and client desktops. On top of that runs your business processes. Moving to a VM would involve moving the former to the cloud. As such you are out sourcing your underlying network infrastructure. And when you say 'manage 1,000 virtual nodes`, who are you going to get to analyse your data, engage with customers and colleagues and maintain your business processes or write your own in-house applications.

Haaa, nice one ...
