- NGINX is pronounced as "engine-ex".
- It is an open-source, fast, lightweight and high-performance web server that can be used to serve static files.
- It has considered as the popular web server behind the Apache web server and Microsoft's IIS.
- In its initial release, NGINX functioned for HTTP web serving. Today, however, it also serves as a reverse proxy server for HTTP, HTTPS, SMTP, IMAP, POP3 protocols, on the other hand, it is also used for HTTP load balancer, HTTP cache, and email proxy for IMAP, POP3, and SMTP.
- It improves content and application delivery, improves security, and facilitates scalability and availability for the busiest websites on the internet.
- In short, we can say that Nginx is just a kind of software that is used in web servers to serve concurrent requests.
- Previously we used to install Apache in web servers to handle these functions, but as the world, in growing and demanding more things at one time, the term concurrency comes into the world and nginx launched for the same thing.
- Nginx was created by Igor Sysoev, with its 1st public release on October 2004 as an attempt to answer the C10k problem. Where C10k is the challenge of managing 10,000 connections at the same time. Today there are even more connections that web servers have to handle. Because of this reason, nginx offers event-driven and asynchronous architecture. This feature makes nginx as the most reliable servers for scalability and speed.
- Some high profile companies using Nginx include IBM, Google, Atlassian, Autodesk, GitLab, DuckDuckGo, T-Mobile, Microsoft, Adobe, Salesforce, VMware, LinkedIn, Cisco, Twitter, Apple, Intel, Facebook, and many more.
