Now that we have the basics covered, let’s take a closer look at the history and background of web servers.

Background

Web servers are the backbone of the internet. They are responsible for serving web pages to users when they visit a website. The web server receives requests from clients (usually web browsers) and responds with the requested content.

In the early days of the internet, the most widely-used web server was Apache HTTP Server, commonly known as Apache. Apache was released in 1995 and quickly became the de facto standard for web servers. It was known for its stability and flexibility, but as the internet grew, so did the need for faster and more efficient web servers.

This led to the rise of NGINX (pronounced “engine-x”) in the early 2000s. NGINX was designed to address the limitations of traditional web servers like Apache. It introduced a lightweight and event-driven architecture that allowed it to handle a large number of concurrent connections with minimal resource usage. This made NGINX an ideal choice for high-traffic websites and applications.

What is a Web Server?

Before we dive deeper into the performance of NGINX, let’s take a step back and understand what a web server is. At its core, a web server is a software application that runs on a physical or virtual server and listens for incoming requests from clients (usually web browsers). When a request is received, the web server processes it and sends back the requested content, such as HTML, CSS, JavaScript, or images.

Web servers can be categorized into different types based on their architecture and the technologies they use. Some of the most widely-used web server stacks include LAMP (Linux, Apache, MySQL, PHP), LEMP (Linux, NGINX, MySQL, PHP), and MEAN (MongoDB, Express.js, AngularJS, Node.js).

What Are The Most Widely-Used Server Stacks?

When it comes to web server stacks, there are several popular options to choose from. Let’s take a look at some of the most widely-used server stacks:

1. LAMP (Linux, Apache, MySQL, PHP): This is one of the oldest and most popular server stacks. It combines the Linux operating system, the Apache web server, the MySQL database, and the PHP programming language. LAMP is known for its stability and wide support in the web development community.

2. LEMP (Linux, NGINX, MySQL, PHP): LEMP is a modern alternative to LAMP that replaces Apache with NGINX as the web server. NGINX is known for its speed and efficiency, making it a popular choice for high-traffic websites. LEMP is often preferred for its performance and scalability.

3. MEAN (MongoDB, Express.js, AngularJS, Node.js): MEAN is a full-stack JavaScript framework that uses MongoDB as the database, Express.js as the web application framework, AngularJS as the front-end framework, and Node.js as the server-side runtime environment. MEAN is popular for its simplicity and the ability to write JavaScript code across the entire stack.

4. WAMP (Windows, Apache, MySQL, PHP): Similar to LAMP, WAMP is a server stack that is specifically designed to run on the Windows operating system. It combines the Windows operating system, the Apache web server, the MySQL database, and the PHP programming language.

These are just a few examples of the most widely-used server stacks. The choice of server stack depends on various factors, including the specific requirements of your website or application.

Our Testing Environment

To determine whether NGINX is the fastest web server, we conducted a series of tests in our state-of-the-art testing environment. Our setup consisted of a VPS server on Google Cloud with the following specifications:
