It’s not been a secret that MS has been working on this. I was at a small meeting at TechEd EMEA where we were asked about this subject and whether it’s something we’d consider. It’s an interesting idea … imaging a SQL instance being a mobile resource, or a web server being mobile? That’s what we’re talking about. Deploy instantly when you need extra resources, move resources around to balance workloads or for fault tolerance.
Microsoft did a demo of their new technology at MMS. What’s really cool is that they appear to be reusing VMM for this.
