Do you ever hear the term “Apache”? However, people who are already in the technology field might be aware of “Apache Projects”. So let’s start to know more about Apache. Before getting narrow down to the topic “Apache Projects” let’s understand first about Apache. So, first of all, we will understand what Apache is.

What is Apache?

Basically, Apache is an HTTP server. It is an open-source and cross-platform web server. Hope you are familiar with the word “server” which means that it is also a computer. But being a web server, it provides data to other computers in form of websites over the internet. This software was developed by an open community of developers under the Apache Software Foundation. The release of this software was under the License of Apache License 2.0. The previous versions of Apache were running only on Linux but now they are available for Microsoft Windows also. The first version of this software was available in the year 1995 but the foundation of this server was started in the USA at NCSA.

During the starting growth of the World Wide Web, Apache played an important role. This webserver served many websites. A survey, reveals that Apache gives service to 29.12% of million websites.

What does the Apache word mean?

The word Apache according to Wikipedia definition is a cute name which is depending on some code and series of software patches. Different definitions of it are available over the internet. Well, you can refer them also. The word Apache is taken as respect for Native American nations, who were known for their quite superior skills. The earlier name of Apache was httpd means “HTTP daemon” which was running on UNIX. The latest version of Apache is version 2.4.46 that is a secure and bug fix release.

So overall you can say that Apache is popular because it delivers HTML pages, multimedia, and CSS style sheets. The main advantage of this software is that it is free to download and use. You can say that the Apache Foundation doesn’t provide direct support but still, documentation is available.

On average, you can say it is a modular application. You can add it to your core application to get more functionality. For instance, it is combining with a SQL database and server-side programming language like PHP. Apache Tomcat is one module of this server that provides java servlet support to clients.

Features of Apache

  • It is a well-optimized server.
  • If there is a large amount of traffic then this software is the best option to handle it.
  • This software also provides the facility to transfer data on minimal hardware requirements.
  • It is easily scalable.
  • This is a free server.

How does Apache Servers work?

It is basically a program that does multiple tasks. As the client requests the server, it collects the data from the server file system and delivers it to the client. You can think of the client as a web browser and the server file system is a place where the website data is present. The Apache server can process multiple requests. To create data and content, the server interacts with various modules, applications, and databases.

Various companies like Apple, Google, PayPal, and Adobe trust Apache and nearly 67% of websites use its services. Usually, the most compatible operating system for Apache is Linux. WordPress hosting providers also use Apache to be used with cPanel for management purposes.

You can use Apache for hosting static and dynamic websites that use server-side scripting languages. The newer version of Apache is proving multi-processing modules and server name indication

Now let’s move to our main topic of discussion “The Apache Projects”. 350+ open-source Apache Projects are provided by Apache Software Foundation (ASF) which is 20 years old.
