Nginx vs Apache

Apache and NGINX are among the most popular and common open-source web servers in the world. Both of these web servers are capable of handling and managing huge workloads and working with other software to provide an all-inclusive web stack.

No doubt, Apache and Nginx share many qualities, however, they should not be considered as totally similar. Each has different capabilities and it is imperative to understand the situation where you may have to reconsider your choice of the webserver.

What is NGINX?

NGINX is a web server that was released in 2004 by Igor Sysoev. Since its release, the webserver has grown in popularity because of its light-weight resource utilization and the ability to scale on minimal hardware.

Nginx is much more than just a web server. It works great at serving static content and is developed to pass dynamic requests off to other software that is best suited for such purposes.

Administrators often use this open-source web server for responsiveness and resource efficiency. The architecture of NGINX makes handling high data load much more predictable in terms of CPU usage, RAM usage, and latency.

History

The reason why Igor Sysoev developed NGINX was to solve the C10k problem, which talks about the problem of designing network sockets, handling 10,000 or more connections.

Sysoev released the open-source webserver to the public in 2004. As the Web continued to grow, Nginx gained more and more popularity as it could surpass Apache HTTP Server in performance. In the year 2016, NGINX finally took over Apache in popularity and became the widely used web server in the world.

Features

NGINX has a rich set of features. It can perform many different roles as per the requirements. Most important among these are:

  • Simplicity: Nginx has a simple yet sophisticated architecture. So developing modules is not a straightforward task. The module developers have to be cautious towards creating an accurate code and to interact properly with the difficult event-driven kernel to go past the blocking operations.
  • OS Support: NGINX runs on various modern Unix-like systems and supports Windows. However, its performance is more stable on the UNIX platform than on Windows.
  • Flexibility: New features and functionality can be added with software modules that can be plugged into a running Nginx Plus instance on demand. Modules are created by both Nginx, Inc. and third-party developers.
  • Security: It is imperative to configure the servers properly and know what each option in the Settings does. There are plenty of guidelines to secure the open-source webserver to prevent security attacks.

Pros

  • Designed to handle a bunch of requests efficiently and effectively with a low memory footprint.
  • The web server has a light-weight architecture and a high concurrency rate to meet the ever-changing requirements of websites.
  • It is better than Apache at handling static content.
  • Provides better scalability and it is highly recommended for websites running on a VPS.

Cons

  • Less community support.
  • Cannot process dynamic content natively.
  • Has a less extensive list of modules.
  • Uses an external processor for the implementation of dynamic content that delays the progress.

What is Apache HTTP Server?

Apache HTTP Server Project is a web server released under the open-source Apache 2.0 license. It hosts web content, like HTML pages, PHP files, audio, and video, and caters content to users when they visit the website.

Apache web server is an open-source software developed by the developer community. It runs on a wide variety of operating systems. The architecture of this server includes the Apache Core and modules.

History

The Apache web server came into existence in 1995 when a team of web administrators started to work with each other as a team to improve NCSA HTTPd. From the beginning, Apache was an open-source web server that could be easily downloaded by any user from any region of the world.

It became popular quickly ever since its launch. All thanks to the big team of volunteers who assisted to expand its feature set. By April 1996, Apache HTTP Server became the most widely used web server in the world. For about 20 years, it retained its position until it was surpassed by NGINX in 2016.

Features

Apache has a lot of outstanding features that can serve different purposes to meet a wide set of requirements. These are:

  • Simplicity: The single connection per process model makes it quite simple to insert modules at any point in time in its web serving logic. Developers add code in a way that even if there would be any bottlenecks, only the worker process running the code would be impacted.
  • OS Support: Apache runs on all operating systems, such as UNIX and Linux. It provides complete support for Microsoft Windows.
  • Security: The Apache team provides advice to Apache projects on existing security concerns and coordinates handling security vulnerabilities.
  • Flexibility: This web server can be easily customized by adding modules. Apache has dynamic modules loading for the longest period of time, so all Apache modules support it.

Pros

  • Considered the best choice for website owners and developers.
  • Can be used with any operating system.
  • Complete support with a lot of software projects.
  • Excellent documentation.
  • Superb community support.

Cons

  • Cannot process so many requests concurrently in case of high traffic as it uses the multi-threaded approach for client requests and every thread can only cater to one connection at one point in time.
  • Consumes more RAM than required, which makes it less efficient because of new processes for each and every request.

Similarities Between NGINX and Apache

  • Apache runs on all major operating systems, such as UNIX, Linux, BSD, and also provides complete support for Microsoft Windows. Similarly, NginX also runs on several UNIX systems and provides support for Microsoft Windows.
  • Both NGINX and Apache HTTP Server are secure web servers. It is imperative to configure the servers properly and also there are a lot of ways to secure the servers from security attacks.

NGINX vs Apache: A Head-to-Head Comparison Table

FeatureApachenGinx
Performance Static ContentSlow in showing static content.It is 2.5 times faster than Apache and takes less memory.
Operating System Support Supports all major operating systems.Supports all operating systems as Apache, however, the performance is a little less satisfying on Windows.
SecurityIt is a secure web server. It is essential to configure the security features.It is also a secure web server and it is important to understand the security features.
FlexibilityIt can be easily customized by adding modules.Version 1.11.5 and Plus release R11 introduced compatibility for dynamic modules.
Support and DocumentationGreat support and detailed documentation are available.Although there was weak support in the beginning, now it has excellent support and documentation.

Which One is the Best?

From the comparison explained above, both Apache and NginX are extremely flexible and powerful web servers. The latest versions of both open-source web servers are highly competitive. Depending upon your business requirements, you may choose the one that best suits your requirements.

We hope this comprehensive guide will help you choose the best server that meets your complex business needs.

Conclusion

Your best pick of the server will be mostly dependent on testing with the existing patterns and evaluating your requirements. The differences between Nginx and Apache really have a huge impact on the performance, capabilities, and execution time required to get the server running in no time. So, select the one that aligns with your goals.
