Introduction
Welcome, dear reader! In today’s digital age, websites are essential for every business, individual or organization that wants to be present online. To achieve that, we need a web server. However, the choice of a web server can make a significant difference in website performance, speed, and security. In this article, we will take a closer look at the web server Nginx. We will explore its advantages and disadvantages and provide valuable insights into its features. By the end of the article, you will have an in-depth understanding of Nginx and the reasons why it is a preferred web server for many.
Chapter 1: What is Nginx?
Nginx (pronounced “engine-x”) is a popular web server that started as a simple reverse proxy server for high-traffic websites. Its founder, Igor Sysoev, developed it to handle the load of Russian search engine Rambler in 2004. Since then, Nginx has become the second most popular web server on the internet, with around 33% of websites using it for hosting and reverse proxying. Nginx is open-source software, and its source code is freely available for modification and distribution.
Nginx accepts and responds to incoming requests from web users on behalf of the website. It can serve dynamic and static web content, handle SSL/TLS termination, cache data, and serve as a load balancer. Nginx is lightweight and uses minimal system resources, making it ideal for high-performance websites and applications that require high traffic handling and speed.
Chapter 2: Advantages and Disadvantages of Using Nginx
2.1 Advantages of Nginx
Advantages of Nginx |
Description |

Nginx has robust security features that protect against various types of attacks, such as DDoS and SQL injection. It also supports SSL/TLS, ensuring secure communication between users and the website. |
Easy integration with other software and technologies |
Nginx can integrate with other software and technologies, such as PHP, Ruby, Python, and Node.js, to serve dynamic content and execute server-side scripts. |
2.2 Disadvantages of Nginx
While Nginx offers many advantages, it also has some drawbacks that need to be considered before using it for web hosting. Here are some of its disadvantages:
Complexity: Nginx’s configuration files can be complex, especially for beginners. Users need to understand the syntax and structure of the files to modify the server’s behavior.
No built-in support for .htaccess files: Unlike Apache, Nginx does not support .htaccess files, which can make it challenging to configure specific settings for individual directories or files.
Less support for modules and plugins: Nginx has fewer modules and plugins than Apache, which can limit its functionality for certain use cases.
Requires additional software: While Nginx can serve dynamic content, it requires additional software, such as PHP-FPM or other application servers, for that purpose.
Requires advanced knowledge: Nginx’s advanced features require in-depth knowledge of the server and the server’s architecture. This can make it challenging for users with less advanced knowledge in web hosting.
