Heroku is a cloud application platform for Ruby/Rails and Node.js. However, the Cedar stack on Heroku makes it possible to deploy other types of applications. In this blog entry, I will first describe how to write a simple Clojure web app using the Ring library and the build tool Leiningen. Then I will show how to deploy this Clojure web app on Heroku, using nothing but Git. I will make a change and see how to deploy that. I will also show how to easily roll back to a previous release.
