Nginx vs Apache: Which Is the Best Web Server for you?

Apache and Nginx, which we pronounce as “engine-x,” are the two major players in the web hosting business. They account for nearly half of all web traffic. They are the most popular and widely used open-source web servers.

Their common goal is to manage diverse workloads and meet the requirements of modern operating systems like Windows and UNIX.

Apache is a well-known web server company, but Nginx has been managing so many websites that it can’t stop. While both web servers cannot be replaced, they each have their own pros and cons.

Summary of Apache vs. Nginx

Apache and Nginx are both open-source web servers that can handle a variety of workloads, to meet modern web requirements. They are conceptually similar; they are also close competitors in the webserver industry.

Apache has been the webserver ecosystem leader for over 20 years. Nginx has its advantages, but it is still a popular choice. Nginx is the future of web apps and websites.

What’s Apache?

Apache HTTP Server, also known as “Apache,” is an open-source web server software that is high-performance and fast. It was developed by developers who the Apache Software Foundation sponsors.

It is a collaborative webserver project that aims to build a secure, robust, and commercial-grade web server in accordance with current HTTP standards.

The project is a collaborative effort by a group of volunteers from all over the world to create the HTTP web server and accompanying documentation via the internet. Since 1995, Apache has been a leader in the web server market. In 2009, it reached 100 million websites.

Apache is still the preferred choice for server administrators because of its power compatibility, multi-platform support, and ease of use. Apache can be used with Linux or Windows. Because of its simplicity and flexibility, Apache became a favorite choice for administrators.

There was an early thirst to invent and try new technologies. Apache was the backbone of the World Wide Web. That’s it. The old saying is that when you are at the top, the only way to go down is up.

What’s Nginx?

One’s loss is another person’s gain. This is exactly what happened. Nginx, a potential rival to Apache, has eroded Apache’s powerful status. One of the early contenders to gain worldwide recognition, Nginx is a solid web server platform that can handle modern web needs.

In straight words, Nginx, a Russian developer, is an open-source, free HTTP server that can be conveniently used as a mail proxy, generic TCP/UDP proxy, or reverse proxy. It is designed to serve large numbers of concurrent users with limited resources efficiently. Nginx was born in a time when it was difficult to handle large web traffic.

Although Nginx can’t compete with Apache on many fronts, Nginx’s asynchronous status makes it an attractive choice over Apache.

It also has a single-threaded architecture and is, therefore, a more intelligent choice than Apache. Administrators love Nginx’s light architecture, resource efficiency, and high concurrency. It can be used as a standalone HTTP Server to enhance the architecture of the webserver as well.

Its ability to efficiently and quickly serve static traffic with minimal hardware resources is unmatched. Nginx could also act as a shock absorber to protect Apache servers against sudden spikes in traffic and other security vulnerabilities.

Nginx offers all the basic HTTP server functions without sacrificing its ability to handle multiple requests using limited hardware resources.

A detailed comparison between NGINX and Apache

Simplicity

Apache makes application development easier. It is easy to add modules to any part of the web-serving logic because it uses a connection per process model. If one process fails, all other operations are not affected.

Nginx, unlike Apache, has a complex architecture that makes application development quite difficult.

This certainly requires an in-depth understanding of how to create efficient code without bugs to achieve the appropriate interaction with event-driven architecture.

Handling connections

One of the key differences between Apache Web Server and Nginx is their ability to handle connections and traffic.

Apache’s development team was well aware of the problems associated with handling multiple connections.

A fast-looping function was created to search for and process events continuously. Every worker can make a connection once an event has been activated.

This type of connection processing allows Nginx to scale even higher, given limited resources. Even under heavy load, CPU and memory utilization remains relatively constant.

The Apache request processing method can be configured in one of the following modules (also called multi-processing modules (MPMs):

  1. The worker model: The beauty of this feature is the creation of child processes that generate a definite number of threads and listener threads. Listener threads listen for connections and pass them on to a thread for processing.
  2. Process model: This is the old method. It’s slow and can refuse connections at high loads. Small sites might not notice this, but larger sites will.
  3. Event model: Like a worker-model, it creates a listener thread that listens and then passes it on to a worker thread.

Nginx workers can simultaneously support thousands of HTTP client connections. NGINX is a highly-respected implementation due to its lightweight architecture, high performance, and scalability.

Dynamic Content

Dynamic content was tested using the same benchmark. It showed the exact same speed. This is because all requests are processed in the PHP runtime environments identical to both servers.

Static Content

Nginx is faster than Apache, it’s clear. It was tested by running up to 1000 connections. The benchmark test showed that Nginx performs 2.5 times faster than Apache and takes less memory.

Nginx is the best choice for concurrent static content handling.

Operating Systems Support

Apache is available on all operating systems, including Windows, Linux, and UNIX. NGINX is stable on UNIX platforms, and it’s also supported on Windows.

Caching

Caching, in very simple terms, is the act of preparing content before a visitor visits it. This means that you can request the content and not search for it. It is ready for them, and they will receive it as soon as possible.

Apache offers three types of caching to increase its performance:

  • File caching is a special service that allows files to be preloaded at start-up, which increases access time and speeds up retrieving them when needed.
  • Two states – shares value with object caching.
  • Smart caching with RFC266 three-state caching – allows smart caching for locally stored dynamic content.

Nginx caches dynamic content, allowing faster load speeds and reducing server load.

These are the two directives that Nginx uses to cache data:

  • Proxy_cache: Activates the cache
  • Procy_cache_path sets the cache path, configuration

Nginx also has the ability to display cached web content even if the server is down.

Caching is not advised in certain situations.

File vs. URI Based Interpretation

Apache uses the Directory block and FilE blocks to interpret filesystem resource requests. The server attempts to locate the file by following the port number and host.

Apache searches the file system for alternative ways to fulfill requests when a match isn’t found.

  • Alias: maps URLs to filesystem locations. It allows you to store documents other than DocRoot.
  • Redirect: works in the following way: server maps an old URL to a new URL and redirects clients so that they can fetch the resources at a different location
  • Location: Working with URLs is possible through the use of blocks.

On the other hand, NGINX allows a server to serve as a proxy, and therefore it mainly deals with URIs. Configuration blocks are used primarily by server and location blocks.

  • Server Block: A config file subset identifies the virtual servers to handle requests. Server administrators can assign blocks to different domains and ports to allow virtual servers to be configured to handle certain types of connections.
  • A location block: It’s a server block that handles requests to various resources and URLs. It routes requests to the correct file locations within the file system.

Flexibility

Apache has had dynamic module loading for quite some time to be customized easily. Nginx Plus, a software module built on Nginx, acts as a load balancer, web server, and content cache. Besides that, Additional software modules can be run from this module.

Both web servers support core operational functions.

Security

Both servers are considered secure, and problems can only result from poor configuration. These are the key points that you should follow in the letter.

For Apache

  • Configure the server configuration file in order to protect your system from .htaccess overriding
  • Modify the permissions for the directory ServerRoot
  • To avoid DoS attacks, adjust the configuration.
  • Always keep your server up-to-date.
  • Counter-check CGI scripts.
  • Make sure you have the correct server-side inclusions.
  • Keep an eye on your logs.

For Nginx:

  • Security headers should be included.
  • Disable server_tokensdirective to hide your Nginx version.
  • To reduce vulnerability exploits by attackers, disable unwanted modules.
  • Unnecessary or unneeded HTTP methods should be disabled.
  • Upgrading your server to the latest version.
  • To avoid DoS attacks, disable resources.

Support and Documentation

Apache HTTP server mailing lists provide community support. You can also get support through Stack Overflow or IRC channels. Third-party channels also offer Apache commercial support, but it does not maintain an official list.

NGINX supports IRC, mailing lists, and Stack Overflow. NGINX Plus, a commercial product, offers additional features such as load-balancing and server monitoring.

Both servers provide amazing documentation. NGINX Wiki is available on Nginx. Apache generally has more support from outside parties because it has been around for longer.

Apache VS NGINX Servers: Pros and Cons

You must select a web server compatible with your website’s needs before you host it. It’s vital to cherish the pros and cons of each server. This section will talk about the same.

The Apache Web Server

Apache certainly is much older than Nginx and is the preferred choice of many webmasters. It works on various operating systems, including Windows, Unix, and Linux.

Advantages to Apache

  • Provides. htaccess can be used on a per-directory basis to override system-wide system-wide settings.
  • Includes mod_security and mod_evasive modules that provide additional security.
  • Dynamically load and unload modules
  • Uses one-connection-per-process model.
  • Excellent support and documentation.
  • High performance for dynamic content serving

Advantages of Apache

  • Websites with high traffic can have performance issues.
  • Comparable to Nginx, static content displays slower.
  • Unable to process multiple requests simultaneously.
  • It can be configured and managed in detail. It isn’t recommended for beginners.

The Nginx Webserver

A lightweight, fast, and simple web server, Nginx, is available. It was specifically designed for websites with high traffic.

Advantages to Nginx

  • Optional configuration to protect against DDoS attacks.
  • It works great in a multiprocessor environment.
  • There are many options available to optimize and deliver static content. It can serve static content 2.5x faster than Apache and takes up less memory.
  • Non-blocking, Event-driven architecture requires less memory and CPU.

The disadvantages of Nginx

  • NGINX doesn’t support Apache’s.htaccess files.
  • Log monitoring tools lacking – Writes logs to files you must manually navigate.
  • A smaller number of modules are available.
  • It is not possible to process dynamic content natively.
  • Supports Linux and Unix operating systems – Windows support is limited.

When to Use Every Server

We can see that Apache and Nginx both have powerful, flexible, and excellent web servers. Apache is the best choice for dynamic content, while Nginx works best for static content and media streams for high-traffic websites. The bottom line is this:

Use Nginx

  • If you’re using dedicated hosting or a VPS.
  • You can manage your incoming traffic and then distribute it to upstream servers.
  • You manage a very popular website and have a lot of static material.

Use Apache

  • If you use shared hosting.
  • Web developers often use Apache because it’s easy to configure.
  • You will appreciate the support community and the abundance of resources that it offers.

Working together: When to use both Nginx & Apache

Now you know the advantages/disadvantages of Apache or NGINX. Both servers work well together in many cases.

NGINX was traditionally placed before Apache in order to act as a reverse proxy. NGINX is able to handle multiple concurrent requests and connections, which allows clients to be accommodated.

Allowing NGINX to only sort requests and processes that it can handle by itself avoids overloading problems. Apache would still be able to process smaller volumes of requests.

NGINX can also be scaled easily because it communicates with server pools and allows for the addition of servers to address specific requests.

Conclusion

We hope the differences between Apache and NGINX are clear now. You can also identify which one is best suited for your needs. Both Apache and NGINX are powerful, flexible, and offer incredible performance. Both can compete with each other.

A variety of tangible differences can significantly impact performance, capabilities, and time to implement each solution. Certainly, no web server can meet all of the requirements and needs of everyone. It is best to choose the one that meets your needs.
