I've been working on production-quality Node.js web applications for a couple of years now, and I thought it'd be worth writing down some of the more interesting tricks that I've learned along the way.

I'm mostly going to talk about maintaining a low-defect rate and high availability, rather than get into the details about scaling that are covered in a lot of other places. In particular, I’ll be talking about load-balancing, process management, logging, and metrics, and the hows and whys of each.
