I have been reminded that "We build roads so everyone can drive the car" this past weekend at SCALE 10x. Rick Clark mentioned it during a cloud computing panel toward the end of the conference, Greg was there too, but sadly didn't wear the penguin hat given to the keynote speakers (his talk is online as well as most of the others presentations).
I do like the comparison of IaaS to road infrastructure in its simplicity and obviousness: building IaaS may not be glamorous, yet it's a fundamental piece of the cloud puzzle. I wonder where the analogy is for the API: is the AWS API like the signs and lights in the streets to direct and control the traffic?
Thanks to all who stopped by at our booth to check with us, having some technical discussion or just to chill. It's always gratifying to put a face to an email address or to an IRC handle. And if weren't around SCALE, you can meet us at our Bay Area Eucalyptus Cloud meetup.
