We started using the free version of VMware server to create some test systems. These were great and a great way to roll out numerous test servers…. (plus as VMware expected we did turn around and buy ESX server which works great)
Whats the catch, the ease of virtualizing makes it lot easier to lose servers. In the real world you don’t often misplace a server but once a ‘server’ become just a file, especially one that is not really being watched after, then sometimes, just sometimes, it might get deleted during a server migration or for any number of reasons.
Be warned, virtualization makes things really easy. Sometimes too easy….
