I am heading down the same path. However I would need Java, Active Perl and a database. I lean towards Postgresql, because I have worked with it in the past. My prior experience (6 years ago) with MySQL was not good.
Oh would also need MS Office.
So my question: Did you work with someone at Amazon to build an AMI or did you select a preconfigured one.
Any feedback on your experience would be helpful.
