RESTful web API using AWS?

[p34cekeeper <wavefront.arbiter@gmail.com>]

I'm currently tasked with developing a RESTful web API as a font-end
for what amounts to a bunch of bog-standard RDB operations. I'm
currently using PHP, which, as it stands is making me feel ill.

While investigating other (more orthogonal) technology choices
(erlang, Scala, etc.), I happened to come across Ada Web Server. I
suppose my question is: is AWS up to the job? Has anyone here done
this before?

It seems to me like AWS' dispatcher mechanisms are ideal for this
purpose, because they don't make assumptions about what you want to do
with the incoming HTTP request (I'm tired of frameworks that force you
into a ham-fisted, code generating MVC implementation).

Any input from experienced Ada engineers would be greatly appreciated.
