The perfect Varnish configuration for Joomla, WordPress & other CMS based websites

IMPORTANT: Read this before implementing one of the configuration files below (for either Varnish 3.x or 4.x+).

USE: Replace the contents of the main Varnish configuration file located in /etc/varnish/default.vcl (root server access required - obviously) with the contents of the configuration you'll use (depending on your Varnish version) from the 2 examples provided below.

IMPORTANT: The following setup assumes a 3 minute (180 sec) cache time. You can safely increase this to 5 mins for less busier sites or drop it to 1 min or even 30s for high traffic sites.

This configuration requires an HTTP Header and a user cookie to identify if a user is logged in a site, in order to bypass caching overall (see how it's done in the Joomla section). If your CMS provides a way to add these 2 requirements, then you can use this configuration to speed up your site or entire server. You can even exclude the domains you don't want to cach

MicroService Proxy Gateway Solutions

Kong, Traefik, Caddy, Linkerd, Fabio, Vulcand, and Netflix Zuul seem to be the most common in microservice proxy/gateway solutions. Kubernetes Ingress is often a simple Ngnix, which is difficult to separate the popularity from other things.

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
