Web Server Technology Basics

What is a Web server?

A web server acts as an intermediary between a client, typically a web browser, and a collection of resources known as websites. Typically, the web server processes HTTP requests and generates HTTP responses, including the content specified in the request.

The roles of Nginx and Apache in the web server landscape

Nginx: the performance maestro

Nginx was originally developed with the main goal of addressing performance issues such as high latency and CPU usage. With its event-driven architecture, it quickly established itself as the ideal choice for high-performance web applications.

Apache: The all-rounder

Apache, the pioneer in web server technology, offers a wide range of modules and is known for its robustness along with reliability. It has a large, active community and therefore offers a wide range of extensions and customization options.

Historical background of Nginx and Apache

The origin of Apache

• Foundation and Development: Apache was released in 1995 by the Apache Software Foundation and is one of the oldest web servers. Originally developed as a fork of the University of Illinois NCSA HTTPd web server, Apache quickly became the web hosting of choice.
• Growth: Apache dominated the web server market for many years and at times had a market share of over 70%. Although market share has declined in recent years, Apache remains a strong choice for many developers and organizations.
• Community and Open Source: Apache has one of the largest open source communities. The software is constantly updated also improved, there are many modules and extensions.
• Influence: Apache has been instrumental in shaping standards such as the HTTP protocol and offers a variety of features that have been adopted in many other web servers.

Apache was launched in 1995 as part of the Apache Group project and has since established itself as one of the dominant web servers on the Internet. Its origins lie in the NCSA HTTPd web server software that it replaced.

The birth of Nginx

• Foundation and development: NGINX was originally developed by Igor Sysoev and released in 2004. Sysoev started the project to solve the C10K problem, which refers to the ability of a web server to serve numerous clients simultaneously.
• Growth: the software quickly gained popularity, especially among websites that needed high performance and scalability. Today, NGINX is one of the most widely used web servers and is used by some of the largest websites in the world.
• Company History: In 2011, NGINX, Inc. was founded to provide commercial products and support for NGINX. in 2019, the company was acquired by F5 Networks for $670 million.
• Impact: NGINX has significantly influenced the way modern web servers are developed and scaled, and is known for its asynchronous architecture.

Nginx was launched much later, in 2004, by Igor Sysoev. Originally developed as a response to the C10k problem, which describes a web server’s ability to manage tens of thousands of connections simultaneously, it has excelled in performance and modularity.

Through this historical outline, it becomes clear how the two technologies differ in their development and core competencies. This contrast will be further explored in the following chapters to provide you with a comprehensive basis for decision-making.

This will give you a deeper insight into the history and influence of NGINX and Apache.

Architecture and Performance

NGINX

• NGINX: Known for its high-performance and low resource consumption. It is particularly well suited for high traffic websites.
• Asynchronous Architecture: One of the main strengths of NGINX is its asynchronous, event-driven architecture. This allows it to handle a high number of concurrent connections with minimal memory consumption.
• Load Balancing: NGINX is known for its efficient load balancing capabilities, which can distribute the load evenly across multiple servers to ensure optimal resource utilization.
• Caching: NGINX offers advanced caching options that help reduce response times and put less load on the server.
• HTTP/2 and SSL: NGINX supports advanced protocols such as HTTP/2 and offers robust SSL options that can further improve server speed.
• Metrics: In various benchmarks, NGINX has often performed better in terms of request rate and latency.

Apache

• Apache: Extensible through modules, which makes it very flexible, but may consume more resources.
• Modular architecture: Apache uses a modular architecture that allows it to load only the functions that are needed. However, this can lead to increased memory consumption if not configured carefully.
• .htaccess: Apache allows granular configurations at the directory level through .htaccess files. Although this is flexible, it can impact performance.
• Keep-Alive: Apache supports keep-alive connections, which can reduce latency but also increase memory consumption.
• MPMs (Multi-Processing Modules): Apache provides several MPMs such as Prefork, Worker, and Event that can affect load times depending on the use case.
• Metrics: In benchmarks, Apache often shows a lower request rate and higher latency compared to NGINX, especially with high traffic.

Each web server has its strengths and weaknesses, and the choice should be based on the specific needs of your project.

Since Nginx interprets requests as URI locations, it can not only act as a web server, but also easily serve as a proxy server, load balancer and HTTP cache.

In the duel between Apache and Nginx, Nginx once again convinces in terms of transfer rate. Here, Nginx outperforms the competition in most cases and clearly in the 500/100 test.

Event-Driven vs Process-Driven Architecture

Event-Driven: Nginx

Nginx uses an event-driven architecture, which is particularly suitable for applications with high loads. This architecture allows for better scalability through asynchronous, non-blocking operations. In short, a single worker thread can handle multiple requests simultaneously.

Process-Driven: Apache

In contrast, Apache relies on a process-driven or multi-threaded architecture. Each request is handled in its thread or process, which provides excellent isolation but limits scalability, especially as request rates increase.

Memory consumption and resource efficiency

Nginx as the clear winner: as you can see, Nginx emerges as the undisputed winner in this test. The differences are so glaring that they are almost hard to believe.

Resource efficiency with Nginx

Nginx scores high in resource efficiency due to its low memory consumption. Since it requires fewer threads, it is less resource intensive, which can play a crucial role in cloud environments and containerized applications.

Apache’s memory consumption

Apache, due to its architecture, can consume more resources in high load scenarios. However, it offers more flexibility in configuring performance parameters.

Performance with static and dynamic content

Nginx: static content performance

Nginx shows its strength predominantly in delivering static content such as HTML, CSS and images. Its architecture is optimally designed to efficiently process large amounts of such data.

Apache: Dynamic content

Apache, on the other hand, is better optimized for dynamic content. Thanks to a wide range of available modules, Apache HTTP Server can handle more complex server tasks, such as server-side script execution.

Benchmarks and case studies

Performance metrics

Various benchmarks show that Nginx is superior in raw performance in most cases, especially when it comes to delivering static content. However, Apache can match it often through specialized configurations and extensions.

Case studies

Companies like Netflix and WordPress.com use Nginx for their high-traffic scenarios. Apache, on the other hand, often finds its place in enterprise environments with many backend applications.

In this chapter, we analyzed the architecture and performance of Nginx and Apache. In doing so, we saw that both web servers have their strengths and weaknesses that qualify them for different application domains.
