Similar to OpenShift, Heroku grants you a limited set of free resources each month (750 free dyno-hours per app) that you can leverage to run Kill Bill and the Kill Bill admin UI — Kaui, for free, in the cloud. This article will guide you through it. The same word of caution applies here as well regarding scalability: your free 750 dyno-hours will allow you to run one 1X dyno for an entire month free of charge, which is limited to 512MB of RAM.

The first step is to install the Herok Toolbelt by going to https://toolbelt.heroku.com/ and verify you can log-in by running heroku login To deploy WARs, you need to install the heroku-deploy CLI plugin: heroku plugins:install https://github.com/heroku/heroku-deploy Kill Bill deployment Grab the latest jar-with-dependencies.war artifact from Maven Central and create our kbdemo app, which will be running Tomcat and MySQL: heroku create kbdemo heroku deploy:war --war /path/to/killbill-server-*.war --app kbdemo heroku addons:remove heroku-postgresql:dev --app kbdemo --confirm kbdemo heroku addons:add cleardb --app kbdemo Kill Bill system properties are defined via the JAVA_OPTS environment variable.
