"if you care about, say, responding to load within ten seconds, VMs aren't a great choice."

That's actually exactly why I would use a VM..

You can spin up, configure, and push into production an application in a new virtual machine in ten seconds? I'd like to see proof of that.

The best I've managed was ninety seconds on my own hardware and three minutes (on average) in AWS.

Ah sorry! I didn't think you meant literally "10 seconds", was assuming you just meant quickly (a few minutes).

I can't really think of a use case though where someone would need more capacity in sub 10 seconds. Maybe if you only intend to scale horizontally with a bunch of 500Mb instances and had little to no room to set an appropriate scaling threshold? What would be a couple examples? With the apps I've seen the past several years generally they have scaling thresholds at 'X' resource and 3 minutes is more than enough to provision extra capacity for their needs.

Also, kind of ironic but your site is giving me a 503 :p
