The response to my earlier post about my experience with a (admittedly, small) Java to Rails port has got me thinking. There's a lot of folks, here, on /., and elsewhere, who dismiss Rails out of hand as not being "Enterprise Ready". And, as much as I want to argue with them, I kind of have to agree. Even though I can't really define "Enterprise Ready", or what "Enterprise Software" is, I can say that there are classes of web-enabled applications that you simply can't solve with Rails right now.
Which begs the question: enough FUD, what is it really missing? I've heard that internationalization is a big one for lack of Unicode support, though that argument doesn't really hold water anymore with Ruby's support for Unicode and the new article on using GetText for translation. And I know the "its interpreted, not compiled or managed" argument, which has merit and for which there is no current answer. But I'm interested in features: what is Rails really missing that would allow it to grow into the next tier of application development?
