Choice of Language for Large-Scale Web Apps?
anyon wonders: "PHP is the most popular language for the web. eBay uses ISAPI (C), Google uses C/C++ (search), Java (gmail), and Python. Microsoft uses ASP (what else?). For small web site, it really doesn't matter. What's your take on language choice for large-scale web applications? Maybe language choice is irrelevant, only good people (developers) matter? If you can get the same good quality people, then what language you would chose? Considering the following factors: performance, scalability, extendibility, cost of development (man-month), availability of libraries, cost of libraries, development tools? Has there been a comprehensive comparison done?"
Ajax, which stands for Asynchronous JavaScript and XML, does not necessarily imply Java on the backend. Many Web application frameworks, such as Ruby on Rails, include Ajax helpers. I'm sure many Java Web app frameworks have also added support for it.
Adaptive Path has a nice article introducing Ajax called Ajax: A New Approach to Web Applications.
