EY's cloud services are great. I'm using it for Boxcar (http://boxcar.io http://boxcar.io) with a decent amount of traffic. The ease of adding additional instances make it an excellent service. Should you need it, their support guys are sharp. If you're by chance already familiar with their filesystem layout, you'll feel right at home. If not, no worries - it's not hard to figure out where things persist at. You can write your own custom chef recipes if you have any requirements outside of the standard "here's the list of gems and *nix packages I need installed." I've used Heroku in the past for "toy" projects, since it's just so damn easy to get something online. It's just lacking, though once you end up doing anything outside of the norm.
