Introduction to NGINX | FreeCourseSite

NGINX is an open-source web server written in C and can be used as a reverse proxy and a load balancer.   This class Is an introduction to NGINX; by the end of this class, you will be able to understand the fundamentals of NGINX and spin up your instance and even secure it with a legitimate certificate.

Here are the topics that I will discuss:

• What is NGINX?
• NGINX Use Cases
• Layer 4 and Layer 7 Proxying in Nginx
• NGINX Timoouts
• Example
  • Install Nginx (Mac)
  • Nginx as a Web Server
    • Static content
    • The regular expression in NGINX
    • proxy_pass
  • Nginx as a Layer 7 Proxy
    • Proxy to 4 backends NodeJS services (Docker)
    • IP_Hash load balancing
    • Split load to multiple backends (app1/app2)
    • Block certain requests (/admin)
  • NGINX as a Layer 4 Proxy
  • Create DNS record
  • Enable HTTPS on NGINX (let’s encrypt)
  • Enable TLS 1.3 on NGINX
  • Enable HTTP/2 on NGINX

A small blurb about NGINX

NGINX is one of a handful of servers written to address the C10K problem. Unlike traditional servers, NGINX doesn’t rely on threads to handle requests. Instead, it uses a much more scalable event-driven (asynchronous) architecture. This architecture uses small but, more importantly, predictable amounts of memory under load. Even if you don’t expect to handle thousands of simultaneous requests, you can still benefit from NGINX’s high performance and small memory footprint. NGINX scales in all directions: from the smallest VPS to large clusters of servers.
