    I refrain from making a snide comment re Amazon's recent cloud outage. (Xen wasn't the issue.)

    We've settled on VirtualBox for a variety of server functions and it works pretty well. I'm also driving a robotic observatory with a Linux box running two instances of XP in VirtualBox. The XP vm's drive the cameras, dome and telescope mount, and we do the processing and archiving on the Linux side. We're basically imaging the entire sky to create a color catalog of all objects in a certain range of brightnesses (10th - 17th magnitude for you astro geeks). It's been running for a year and a half, one system in New Mexico and one down in Chile, and it's worked like a charm.

The laws of necessity, of self- preservation, of saving our country when in danger, are of higher obligation. To lose our country by a scrupulous adherence to written law would be to lose the law itself, with life, liberty, property, and all those who are enjoying them with us; thus absurdly sacrificing the end to the means."

    Nice. Yeah I'm well versed in what happened with AWS, and despite the recent human-caused outage they still have a very nice service offering.

    Oh yeah. I was just having a chuckle at their expense. We use their service quite a bit for Mars atmospheric simulations, and they were very forthcoming about what happened. It just shows how difficult it can be to predict how badly and rapidly things can go haywire in such complex systems.
