Spring Roo is a tool to offer rapid application development on the Java platform. I already explained when to use it: http://www.kai-waehner.de/blog/2011/04/05/when-to-use-spring-roo. Spring Roo supports two solutions for Cloud Computing at the moment: Google App Engine (GAE) and VMware Cloud Foundry. Both provide the Platform as a Service (PaaS) concept. This article will discuss the Cloud Foundry support of Spring Roo. GAE was discussed in part 1 of this article series (http://www.kai-waehner.de/blog/2011/07/18/rapid-cloud-development-with-spring-roo-%E2%80%93-part-1-google-app-engine-gae).
Deployment of a Cloud Foundry Application to the Cloud
The reference guide of Spring Roo gives an introduction at http://www.springsource.org/roo/guide?w=base-cloud-foundry, which describes the combination of Spring Roo and Cloud Foundry. In a nutshell, there is not much to do to deploy your (CRUD-) application in the Cloud Foundry cloud.
