Does anyone have a good link to know what technologies and platform is being used to power the Android Marketplace?
What would be the best way to create a cost effective "clone" for a smaller audience?
Is it built on top of Google App Engine? Does anyone have an article describing the architecture behind that project?
I think people are not reading the question correctly... I am looking for an overview to the architectural problem, not just that it's a servlet, or asp page, etc... I am wondering if there is a paper or article on this topic, or Amazon Android store.
