Support for Grails on Heroku was recently announced and I’d like to walk you through the steps to create a simple Grails app and then deploy it on the cloud with Heroku. Before you get started install Grails 2.0.0, install the Heroku toolbelt, install git, and signup for a Heroku.com account. Don’t worry, you won’t need to enter a credit card to give this a try because Heroku gives you 750 free dyno hours per application, per month.
