online Node.js server

Question

Is Node.js mature enough to make entire web applications in it? I mean entirely in Node.js. I read somewhere that for some reason there should be (for example) nginx behind

Answer 1

node v0.6 introduced cluster, allowing multiple processes to fork and listen to a single socket. This allows node to take advantage of multiple cores/cpus. This was one of the big reasons to use something like nginx, as before cluster, a single node process would hog up an entire ip/port.
