Sounds like a poster scenario for Saas!

Live Migration for desktops? Offline desktops in VDI maybe the answer there.

Now we've stepped off the Merry Mixer and boarded the Rotor, and the floor has already dropped. http://en.wikipedia.org/wiki/Rotor_(ride)

To go deeper into the rabbit hole – what if you're protecting the VMware database servers with DRS, too? Woohoo! The protection mechanism flowcharts boggle the mind…

Yeah.. now we just need live migration for Desktop PC's... (presumably with KVM and client-side hypervisor required)

And all other server resources. Live migration of things like DHCP servers, file servers, Exchange Mailbox stores, etc, between servers.

And aribtrary applications, like browser windows. It would be great to be able to right click a browser windows (with all their tabs), and just move them.

For most individual apps, there's no reason for them to be tied to specific hardware anymore. And even apps being tied to particular running OS instances ought to go away.

If every important server app implemented a seamless motion capability, it could take over a bit of what Virtual machine live migration does.

In some ways, the app itself is in a better situation to handle application performance issues for load balancing; app-aware clustering may ultimately be able to even divide load at a more granular level than the "whole OS instance" level, which DRS operates at.

Much like virtual machine migration has replaced some uses of clustering implemented at the hardware level, that OS instances ran on top of.

App level migration techniques could replace some uses of virtual machine level migration that virtual OS instances ran on top of.

I should clarify… I had not had coffee and dont want people to be mislead. PolyServe does consolidate SQL workloads. But it does not do live migration. The SQL service still needs to be started on the node that it is being moved to and stopped on the other node, so you will get a blip… So I apologize for any disinformation. It's still a cool piece of software.
