This plugin makes it easy to deploy a Grails application to Amazon EC2. It takes care of configuring MySQL, Tomcat and Apache and deploys the application. The plugin currently provides the following scripts:
* cloud-tools-deploy - deploy the web application
* cloud-tools-describe - display information about the running EC2 instances
* cloud-tools-redeploy - redeploys the application
* cloud-tools-stop - terminates the instances
I've also started to expand the project's wiki.
