Apache Web Application Architecture

When it comes to building web applications, Apache plays a crucial role in the overall architecture. It is part of the widely-used LAMP stack, which stands for Linux, Apache, MySQL, and PHP.

Linux serves as the operating system that handles the application’s operations, while Apache acts as the web server responsible for processing requests and serving web assets and content through the HyperText Transfer Protocol (HTTP).

MySQL, on the other hand, is the database system that stores information in a queryable format, allowing web applications to retrieve, manipulate, and manage data efficiently. PHP, as a server-side scripting language, works seamlessly with Apache, enabling developers to create dynamic web content.

Although web applications may vary in their functionalities and purposes, they often share similar architectural structures. In addition to the core LAMP components, other elements such as Firewalls, Load Balancers, Web Servers, Content Delivery Networks (CDNs), and Database Servers can be integrated to enhance the application’s functionality, performance, and security.

It is worth noting that separating the database and application servers is a recommended practice, as it allows for better scalability, performance optimization, and improved security measures.

Web Server Landscape

The web server landscape comprises various technologies, with Apache being one of the most popular web servers in the industry. Back in the late 90s and early 2000s, Apache dominated the market, serving over 50% of active websites. However, the current market scenario shows Apache holding just under 40% of the market share, with NGINX as the second most popular web server. Microsoft IIS holds around 8-10% of the market.

The web server landscape is constantly evolving with advancements in technology and the emergence of new servers. This dynamic environment ensures that web servers can adapt to changing user needs and technological advancements. As a result, web developers and system administrators have a variety of options to choose from when selecting a web server for their applications.

Let’s take a closer look at the current market share of web servers:
