Clustering: The basics

The trick? pass the file descriptor from a parent process and have the server.listen reuse that descriptor. So multiprocess in their own memory space (but with ENV shared usually)

It does not balance, it leaves it to the kernel.

In the last nodejs > 0.8 there is a cluster module (functional although marked experimental)

http://nodejs.org/api/cluster.html
Simple cluster example:

tl;dr

Don't run as root.
For sessions, set httpOnly (and secure to true if running over SSL) when setting cookies.
Use the Helmet for secure headers: https://github.com/evilpacket/helmet
Enable csrf for preventing Cross-Site Request Forgery: http://expressjs.com/api.html#csrf
Don't use the deprecated bodyParser() and only use multipart explicitly. To avoid multiparts vulnerability to 'temp file' bloat, use the defer property and pipe() the multipart upload stream to the intended destination.
