2.1 Deploying: how a website gets onto a server

Deploying means putting a website or app on a server so people can reach it.

What happens when someone opens your domain

1. DNS turns the domain into your server's IP address.
2. The visitor's browser connects to your server on port 80 (http) or 443 (https).
3. nginx, the web server, sees which domain was asked for.
4. It sends files (a website), or passes the visit to an app running on the server.
5. HTTPS (the padlock) protects everything sent. It needs a certificate, which is free.
