Now, I'm a huge Gabriel fan, so this was interesting in part because I feel for the guy and hope nothing of great value was stored on those servers. However, my interest was peaked by the realization that this highlights one of the key values of decoupling software from hardware. To illustrate this advantage, I'd like to paraphrase Heisenberg's famous Uncertainty Principle:
In shared resource computing, you can locate the server, but you cannot firmly define what is running on the server (over time); conversely, you can define the software image, but it is difficult to firmly locate which server it is running on (over time).Thus, if someone comes into a data center that is sharing server resources in a utility computing like model and steals a server, they will very likely get no data whatsoever. Conversely, if they want the data, they have to steal all of the storage associated with the server image, which in many environments is spread amongst several physical drives; is dependent on the network infrastructure in which it is running; and is useless without both a compatible server to execute it, and a compatible management system to deliver it to that server.
To me, this greatly enhances system security over dedicated server models. If Gabriel's stuff had been PXE booted on random servers around the hosting center, from distributed storage systems, he may have foiled his thief's plans. He certainly would have made it much more technically difficult for them.
The more I learn about decoupling software from hardware, whether through server virtualization or policy-based dynamic deployment, the more I think its a no-brainer for most computing applications. Plus, it makes SLAuto possible--which has its own benefits, of course.
