This document summarizes a presentation by Everett Toews on using jclouds to access multiple cloud providers. The presentation introduces jclouds, an open source toolkit that provides a common API for interacting with various cloud platforms. It then covers setting up accounts with Rackspace and HP cloud and discusses basic cloud terminology. The agenda includes an overview of jclouds, a compute example, and next steps for learning more.
