Smith Floyd. High Performance Caching with NGINX & NGINX Plus

Nginx.com. — 43 p.NGINX is the leading web server and reverse proxy server for high-performance websites, in use by more than 50% of the top 100,000 websites.One of the most important capabilities of NGINX is content caching, which is a highly effective way to improve the performance of a website. In this ebook, we describe how NGINX caches, how to use caching and cache clustering, and some of the ways that you can improve performance.We’ll do a deep dive into how content caching really works so that you’re equipped to debug and diagnose what’s happening within NGINX. We also round up some clever hints and tips to give you fine-grained control over what NGINX does with content that can be cached, and point you to additional resources to take caching even further.Caching takes the burden of serving and generating repetitive content away from your upstream servers, so they’re freed up to run the applications that your business really needs. This gives your end users a better level of service and increases the reliability of your service as a whole in the face of big spikes of traffic from the Internet and, potentially, failures of upstream servers.This ebook is adapted from a wide range of caching-related resources available on the NGINX website.
