Google App Engine enables large and small businesses alike to host and run their web-based applications on Google's highly scalable infrastructure -- Google takes care of the maintenance, load balancing, and other server-side management tasks so you can focus on building out the core functionality of your web app. On the other end of the spectrum, Google Web Toolkit (GWT) enables developers to create rich, AJAX-enabled, web applications using a familar language (Java) and environment (Eclipse), which then get compiled to optimized JavaScript. This presentation will open with an introduction to Google's Eclipse plugin and demonstrate how to create a new servlet-based Java web application and deploy it to the cloud within 30 seconds -- all without leaving Eclipse! I'll then shift into a deep dive of both GWT and App Engine, showing how both work, how much they cost (hint: free to start!), the various features and services included for both, and more, and there should be plenty of time for Q&A afterward. You don't have to be entrenched in the Web 2.0 world to gain insight from this session. GWT makes it easy for businesses that are just starting to move their applications into the cloud, while maintaining an advanced feature set for those that have been there for years, and App Engine makes it especially easy to get your apps up and running in a scalable fashion. Whether you're just starting to investigate web development and cloud hosting providers or you are already a seasoned pro with other solutions, this session is for you.

leverage others' strengths

14. Enter App Engine...

15. Google App Engine pitch #1
"Run your apps on Google's
scalable infrastructure"

16. Google App Engine pitch #2
"Run your apps in Google's
managed cloud"

17. Google App Engine pitch #3
"Get your apps running reliably
and ready to scale in
30 seconds"

18. Reliability:
Building web applications is hard

19. Scalability:
With just a few users...
...tools, platform and design don't matter too much

20. Scalability:
With lots and lots of users...
...you must design for scalability
