Wow!  What a day and it is not yet over.  The keynote, the sessions and the Sites Hackathon are over and now it is party time - I can hear the Foo Fighters playing in the background.  This is actually my second Dreamforce, I presented at the very first Dreamforce as a Salesforce partner back in 2003.  At that time, there were a few hundred attendees, the Web Services API was in version 1.0, and I don't think the term Cloud Computing was even around.  Today, there are almost 10,000 attendees here, version 14 of the API is in GA and hundreds of companies small and large run their business in the cloud.  All this is a short span of five years - Salesforce.com and its customers have changed an entire industry!

There were too many exciting announcements at the key note - Jon has a good summary for the platform piece here.  Let me talk about one of them - Force.com for Amazon Web Services.  I am particularly excited about this because I believe that a platform should let developers easily reuse functionality from existing programs irrespective of the language it was written in (in the world of languages there are no ugly babies).  Now you can with the integration with EC2. If you have some code already written in Java (or anything else) and you want to combine with some new functionality on Force.com, you can run that Java piece in the Amazon cloud and control and interact with it from Force.com seamlessly.  Now your entire composite application is running in the cloud.  The integration with Amazon's S3 let's you store and access your documents from Force.com.  I am looking forward to playing with this new toolkit soon.

The sessions were all fantastic and I would encourage you to go through them - they are great learning resources.  If you want to pick just one thing to watch, I would recommend the keynote.  I bet you that you will not only get excited about Cloud Computing in general but start thinking about your application in new and different way.
