I have written articles about the benefits of a virtual environment before, but I am reminded by a client once again that whilst VMware and Citrix alike are worth 'X' billion dollars, the IT world still needs to wakeup to virtual machines. IT managers are still paying enormous sums for hardware and experiencing all the pain of running servers estates, when a simple ESX server will do the job within a contained, remotely managed environment. Helpful tip of the day - VMotion used in-line with VMware can ensure your server is up and running on another ESX machine, potentially on another site (say DR) with the same state and the same everything (ip, mac etc...) within seconds. Makes clusters look like wind up toys.

Wake up and virtualize. I am encouraging users of virtual environments to post up code that helps easily build and manage virtual estates (like NRLComputers VPloyment)
