Coming from the traditional root-server world and using EC2 since 2007 basically as a virtual replacement of root boxes, I always wanted to go one step further to get rid of all that unproductive admin stuff (sorry admins, but I’m a developer by heart) and for easy scaling. With a PaaS provider like Heroku, (Engine Yard) or AppFog focussing on developer needs, I feel I found a good new playground.
