Jeff Barr, the Chief Evangelist for Amazon's Web Services (AWS) wrote to let me know about another Amazon Web Services day. They did the original at last year's ETCon in Santa Clara. This one's in San Francisco on March 17th, and like last time, its free. I blogged last year's event. If you want to understand more about how AWS works and see some great examples of it in use, then this is a great event to attend.
