If you are a tech geek, you would certainly know that websites on the internet are hosted through a robust and reliable server to offer an optimal user experience.
While there are numerous servers to choose from, one server that has always been the talk of the town and the top pick among website owners is Apache.
We are sure that your head is flooded with questions right now, like what is the Apache server, why webmasters are inclined toward it, how it works, what are its pros and cons, and so many more.
But hey, stop right there! Read this write-up, and by the end of it, you will have all your answers.
What is Web Server?
Web server refers to software reciprocating HTTP requests sent by web users. The main purpose of using a web server is to host websites on the internet and exhibit the content, visuals, and other elements of a website or page to the users.
Besides the above usage, web servers are also utilized for storing information and website elements, such as HTML documents, images, CSS and JS files, etc.
Generally, web servers process on dedicated devices or server hardware integrated with the latest softwares like Ngnix, Microsoft IIS, and the one this blog is about — Apache.
What is an Apache?
As previously mentioned, Apache is a web server allowing websites to display content, visual elements, and other components to the user upon sending an HTTP request.
To give you an overview, Apache was first developed in 1995 as a free and open-source web server by the Apache Software Foundation.
Besides being a cross-platform server, Apache is a widely preferred software among website owners for its robustness, versatility, and a suite of features, including modular architecture and extensive support.

1. Open Source Server
One of the main reasons raising the popularity of Apache is the accessibility of the source code. Simply explaining the source code of Apache is free, allowing server users and developers to modify and extend the capabilities according to their needs.
This is not only a cost-effective solution but also helps the server users and developers to identify & fix bugs and contribute improvements.
2. Reliable Solution
From Slack to LinkedIn and Netflix to Airbnb, almost everyone uses Apache, and the reason is reliability. Apache has been in the market for more than two decades, and throughout this period, it has undergone numerous upgrades to enhance the user experience.
The improvements have transformed into a one-of-a-kind, powerful, and reliable server, adaptable to any environment.
3. Community & Support
Another perk of Apache is constant community support. The server has a diverse and active range of communities comprising developers, experts in the field, and Apache users, sharing their ideas and knowledge for enhancing the server.
You can access forums, join groups, and mail relevant resources to seek their guidance and advice on the topic.
One of the amazing benefits of using Apache is that users and developers can seamlessly customize it according to their requirements since it is flexible and extensible software.
Its architecture allows you to easily integrate additional components and extensions, such as API, softwares, features, etc., without manipulating the heart of the server.
5. Unparallel Performance
Apache is known for its ability to manage high loads while ensuring unbeatable performance. Meaning every time there is an incoming request, it will efficiently split the data into available resources to strike a balance and enhance the performance & overall output.
You can even add more machines and nodes when there is a requirement to increase the storage capacity.
6. Effortless Setup
The setup process of Apache is a piece of cake, even for non-technical users. All you need to do is download the compatible and latest version of the server from the official website. Once you download the server, run the installer or package manager command to execute the process.
That’s it! You are now all set.
You can customize the listening port, the document in the root directory, and so on, and start using Apache.
Like WordPress, this one, too, has minimal code usage. Furthermore, additional features, modules, and other enhancements can also be implemented to improve performance and usability.
How Apache Works?
As previously discussed, the primary function of Apache is to showcase content and other elements of a website/webpage. While everyone is familiar with the surface level, very few are aware of what goes behind the process.
Let’s understand that!
Apache works on the HTTPS protocol, ensuring secure and uninterrupted communication between the client and server. Supposedly, a user has landed on the home page of your website. As soon as Apache receives a request from the client side, it gradually and chronologically exhibits the text, images, videos, and so on to the user.
Apart from content and visual delivery, Apache offers numerous other features, including server control & customization, maintaining access logs, and more which we will be underlining in our next section — Features of Apache.
