Variations exist, often incorporating other technologies like MariaDB (a MySQL fork), Python, Ruby on Rails, or Node.js, depending on the specific application requirements.
These stacks provide a standardized and well-supported foundation for deploying and managing web applications.
Architecture of a Typical Linux Web Hosting Setup
The following describes a diagram illustrating the architecture. Imagine a layered structure.
Layer 1: Client – This represents the end-user’s web browser, making requests to access a website.
Layer 2: Load Balancer (Optional) – This distributes incoming traffic across multiple web servers, improving performance and availability. For example, a load balancer might direct 50% of traffic to ‘webserver1’ and 50% to ‘webserver2’.
Layer 3: Web Servers (Apache/Nginx) – These servers receive client requests, process them, and return the appropriate website content. They interact with the application server.
Layer 4: Application Server – This handles the dynamic aspects of the website, interacting with databases and processing user input. It could be running PHP, Python, or other languages, based on the website’s technology stack. This layer is often where the code for the website resides.
Layer 5: Database Server (MySQL/MariaDB/PostgreSQL) – This stores website data, such as user information, product catalogs, or blog posts. The application server queries the database to retrieve and update information.
Layer 6: Operating System (Linux) – This forms the underlying foundation of the entire system, managing hardware resources and providing the runtime environment for all other components. It manages processes, security, and file systems.
Layer 7: Network Infrastructure – This encompasses all networking components, including routers, switches, and firewalls, ensuring connectivity and security.
Data flows from the client through each layer, with each layer performing its specific function before passing the request or response to the next layer. For example, a request for a webpage might travel from the client to the load balancer (if present), then to the web server, which retrieves the content from the application server, potentially querying the database, before returning the webpage to the client.
Error handling and security measures are integrated at various points in this process.
