Session Presented @IndicThreads Cloud Computing Conference, Pune, India ( http://u10.indicthreads.com ) ------------ The Java EE 6 platform is an extreme makeover from the previous versions. It breaks the “one size fits all” approach with Profiles and improves on the Java EE 5 developer productivity features. It enables extensibility by embracing open source libraries and frameworks such that they are treated as first class citizens of the platform. NetBeans, Eclipse, and IntelliJ provide extensive tooling for Java EE 6. But how can you leverage all of this on a cloud ? GlassFish v3, the Reference Implementation of Java EE 6, can easily run on multiple cloud infrastructures. This talk will provide a brief introduction to Java EE 6 and GlassFish v3. The attendees will learn how to create a simple Java EE 6 sample application and deploy them on GlassFish v3 running locally. Then it will deploy that sample using Amazon, RightScale, Joyent, and Elastra cloud infrastructures. It will also show how servers are dynamically provisioned in some environments to meet the demand. The talk will also explain the advantages of each approach enabling you to choose the optimal strategy for your environment. Takeaways from the session The attendees will be able to learn how to deploy a Java EE 6 application in different cloud environments. They’ll also learn about the pros/cons of these infrastructures.
