How Hosting Works

Web Servers and Hosting Explained

A website needs a place to store files, images, code, and databases. Hosting is the service that stores these files on a server and delivers them to visitors through the internet.

Core Idea

You rent space on a server. When users type your domain, the server sends your website to their browser.

Main Hosting Types

1. Shared Hosting: Many websites share one server. Cheap and basic.

2. VPS Hosting: Virtual Private Server. More power and better performance.

3. Dedicated Hosting: You get an entire physical server.

4. Cloud Hosting: Runs on distributed servers. Auto-scaling. Used by AWS, GCP, Azure.

5. Static Hosting: For static sites. Examples: GitHub Pages, Netlify, Vercel, Cloudflare Pages.

What Hosting Provides

Hosting provides:

• Storage for your files
• A public IP address
• A web server program
• Bandwidth
• Security updates

How Hosting Connects to Your Domain

You point DNS records to your hosting server IP using A or AAAA records. When visitors type your domain, DNS finds your hosting server and the server sends back your site.

What Is a Web Server

A web server is software that listens for HTTP requests and sends back responses like HTML, CSS, JS, images, or API output.

Examples of web servers:

• Nginx
• Apache
• Caddy
• IIS
• Node.js based servers
• Python servers like Gunicorn or Uvicorn

What a web server does:

• Listens on port 80 (HTTP) or 443 (HTTPS)
• Accepts HTTP or HTTPS requests
• Finds the correct file or application
• Sends the response
• Logs activity

Static vs Dynamic Content

Static content: HTML files, images, CSS, JavaScript files served directly.

Dynamic content: Pages generated by code like Node.js, Python, PHP, or Ruby.

Web Server Plus Hosting

Your hosting environment runs a web server. Your domain points to that server. Visitors hit your server. Your server sends back web pages.

Conclusion

Hosting provides the infrastructure to store and serve your website. A web server is the software that handles requests and delivers content. Together with DNS, hosting makes your website accessible to the world through a domain name.
