Then, the browser will send an HTTP `OPTIONS` request to the `:80`-backend, and if the backend sends the appropriate headers authorizing the communication from this different origin (`http://localhost:8080`) then the `:8080`-browser will let the JavaScript in the frontend send its request to the `:80`-backend.

To achieve this, the `:80`-backend must have a list of "allowed origins".

 5. It sends the HTTP request and reads the response.

No(s) servidor(es) DNS, você configuraria um registro (`registro A`) para apontar **seu domínio** para o **endereço IP público do seu servidor**.

Você provavelmente fará isso apenas uma vez, na primeira vez em que tudo estiver sendo configurado.

Essa parte do Nome do Domínio se dá muito antes do HTTPS, mas como tudo depende do domínio e endereço IP público, vale a pena mencioná-la aqui.
