Translator: Alfredcheung on the topic of building high throughput Web applications, Nginx and Node.js are natural couples. They are all based on the event-driven model and are designed to easily break through the c10k bottlenecks of traditional Web servers such as Apache. Preset configurations can be highly concurrent, but there is still work to do if you want to do more than thousands of requests per second on inexpensive hardware. This article assumes that readers use Nginx's httpproxymodule for upstream node ....
