This document provides an overview of Apache jclouds, an open source library that helps developers build applications in the cloud using Java. It introduces jclouds, describes how it provides portable APIs to work with multiple cloud providers and services, and demonstrates how to use jclouds to interact with the Rackspace cloud through code examples. The presentation agenda includes sections on cloud concepts, jclouds features and benefits, a live demo, and a Q&A.
