A great article, even if a bit self serving: written by Heroku people, and it is relatively easy to develop and deploy Twelve Factor Apps using Heroku services.

I like that the article was written as a response to observing problems deploying real apps. I just emailed this link to two of my customers, just in case they did not see it. There are too many good points in the article to comment on.
