A general help regarding the tools required for cloud app without ssl

I know this may be basic, but i really need your help to getting started because i need to choose the right horses to ride now .

I need to have some cloud application that do this :

User can access to it via http requests (not ssl! ) and perform one of these(according to the rest api request) :

1. register to some basic table with an ID and a few other fields.
2. check some conditions from a user table, and then send a push notification (APNS) to iOS device (Amazon sns? )
3. check some condition and perform some https(ssl) request to some other third party service.

So basically save basic data, make basic decision based on the data, and preform one of the 2 : push notification / other https request . Should serve many users.( 1000- 10,000)

I know only C/C++/objective-C(very good).

Parse.com services are not good, because its an ssl ( i cant use ssl for the API)

Amazon AWS seems like the best choice , but i wonder how to start and if its something that would take a long learning process or not ,and what exact service do i need.

Any advice on how to make this app alive ,what service is fit the best, where to start, would be great .
