Amazon Web Services released their Platform as a Service offering on Wednesday, January 19th. I've gotten an opportunity to play with it and I'm quite impressed. I created a seven-minute screencast that takes you through the steps to deploy and configure an application/environment using Elastic Beanstalk. In this screencast, you'll see how easy it was to get a Hudson CI server up and running in an EC2 environment. Furthermore, Elastic Beanstalk provides automatic scaling, monitoring, configuration right 'out of the box'. It's worth checking out.
