This document provides an overview and introduction to using jclouds, an open source multi-cloud toolkit for Java. It outlines the key aspects of jclouds including that it is cross-cloud, open source, has a community and portable APIs. The document then covers setting up cloud accounts, installing jclouds and walking through a compute example to launch servers on Rackspace and HP clouds. It concludes with next steps and thanks.
