Scalability, latency, and throughput are key performance indicators for web servers. Keeping the latency low and the throughput high while scaling up and out is not easy. Node.js is a JavaScript runtime environment that achieves low latency and high throughput by taking a “non-blocking” approach to serving requests. In other words, Node.js wastes no time or resources on waiting for I/O requests to return.

Let me explain…

In the traditional approach to creating web servers, for each incoming request or … Read the rest
