Oracle APEX on AWS

I only know of one documented public case study, but it is documented very well!  While at Oracle, I co-authored the book Migrating to the Cloud.  The Oracle partner JSA2 (http://www.jsa2.com) authored a chapter (13) in the book which goes into extensive detail on moving a Powerbuilder/Oracle/on premise application to APEX/Oracle/AWS.  The book can be found here:  http://www.amazon.com/Migrating-Cloud-Oracle-Client-Modernization/dp/1597496472/ref=sr_1_1?ie=UTF8&qid=1355941590&sr=8-1&keywords=migrating+to+the+cloud
