Article: RESTful Services with Erlang and Yaws
Erlang has seen a renewed interest because it is, together with the accompanying Erlang/OTP framework, built specifically to exploit parallel computing resources. In the article, Steve shows how Erlang's features are a match for implementing RESTful services, specifically discussing how to map an application's URI space to Erlang program code.

Thanks for the article. In my own testing, I've seen Yaws fall over and die under a load of ~20 concurrent requests. This really begs the question, what can we do to repeat Joe's tests? The documentation and code of "the test" are sparse, and they aren't public so it's impossible for anyone to reproduce the same numbers. Given that, I can only assume the Yaws numbers don't take into account dynamic content, something that is important to most developers. Any thoughts there?
Apples And Oranges
First, are Apache and Yaws comparable? How much of Apache's functionality set is found in Yaws? Second, what was the test configuration for that graph? Also, no mention is made of the follow-up benchmarking
I mean, if a writer starts an article with: "Whether or not you should use X, here's how you'd use X...", shouldn't the "whether or not" part be well-established rather than open to debate?
Although the example almost reaches REST in a really simple way, it is just missing the HATEOAS point when leaving the hypermedia aspect behind. It is much easier to develop thatn SOAP based solutions, but without hypermedia support, both clients and servers are coupled in a way that REST systems should not.
