Udemy – Introduction to NGINX

Introduction to NGINX

Understand and Deploy Layer 4/Layer 7 Load Balancing, WebSockets, HTTPS, HTTP/2, TLS 1.3 with NGINX (With Docker)

What you’ll learn

• Layer 7 Load Balancing between services
• Layer 4 Load Balancing between services
• Setup NGINX as a Web Server
• TLS Passthrough vs TLS Termination
• Block Undesired Requests and Re-route requests to different services
• Enable HTTPS with letsEncrypt
• Enable HTTP/2 with NGINX
• Enable TLS 1.3 with NGINX
• NGINX Timeouts
• Scaling WebSockets with NGINX
• Load Balancing WebSockets with NGINX

Requirements

• Basic understanding of networking and coding
• Any computer (Windows, Mac or Linux)

Description

NGINX is an open-source web server written in C and can also 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 own 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
    • Regular expression in NGINX
    • proxy_pass
  • Nginx as a Layer 7 Proxy
    • Proxy to 4 backend 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 (lets 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 all the way up to large clusters of servers. You Can Learn Cloud Computing Essentials: Linode, Linux, and LAMP Stack

Who this course is for:

• Engineers who want to deploy Web Servers
• Engineers who want to understand how to enable TLS and HTTPS
• Engineers interested in Proxy technology, reverse proxy and load balancing
• Engineers who want to use NGINX to scale HTTP and WebSockets applications
