I am going to give amazon EC2 a try by moving my drupal site to it. At present the site is on a VPS running Ubuntu 10.04 and served through nginx+fastcgi.
Regarding that there are literally thousends of Amazon Machine Images (AMI) , I am wondering which suits the best for my need? After a brief research I found a pretty good general tutorial here, however a bit dated, that suggests RightScale. Also chapterthree offers a customized image, but I am not sure what is the best solution.
The AMI's are kinda outdated now, but if you follow these instructions from the pantheon group on g.d.o using one of the Alestic Ubuntu 10.4 ami's as a base you should be fine to roll your own.
