Cloud Infrastructure for Beginners: Server, Domain, and DNS Explained

Cloud infrastructure becomes easier to understand once you separate the parts. A website usually depends on a server, a domain name, and DNS.

Server

The server is where the website lives. It stores the files or runs the application so users can access the site.

Domain

The domain is the address people type into the browser. It is the human-friendly name that points to the website.

DNS

DNS connects the domain to the correct server. You can think of it as the routing layer that tells the internet where the site should go.

Takeaway

Once you know what each piece does, cloud infrastructure stops feeling mysterious and starts feeling manageable.
