...nds; which one you use depends on your exact requirements.
I'm going to start with what's widely considered the "best" approach:

Why shouldn't I use PyPy over CPython if PyPy is 6.3 times faster?
...cial.
I think it's possible that if PyPy gets into a stable state, it may start getting more widely used. I also think it would be great for Python to move away from its C underpinnings. But it won't happen for a while. PyPy hasn't yet reached the critical mass where it is almost useful enough o...

I wonder how long it will take for REST-I to develop now with it starting to look more and more SOAP like with RAML , Swagger and WADL slogging it out for the de-facto standard of being REST.
