Matthew McCullough's presentation to DOSUG on the Google App Engine's new Java language and JSP/servlet support. Covers the current definition of what Cloud means, and why you'd want to use it. All materials are highly subject to change, as this talk covers the Java Beta GAE support on the App Engine just 27 days after launch.
