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.

FWIW: I didn't produce the content presented here (the outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.

What's an Effective Engineer?

Overview

DevSecOps has finally become popular within the wider IT industry in 2019. I started as a web developer in 2001, learned about testing automation, system deployment automation, and "infrastructure as code" in 2012, when DevOps has becoming a popular term. DevOps became common after the release of The Phoenix Project in Jan 2013. It has taken 7 years for security to become integrated within the devops methodology. The following is a list of concepts I go through with project owners, project managers, operations, developers, and security teams, to help establish how mature their devops and security automation is, and to help them increase that maturity over time.
