[How-To] Emby Server on Windows Server with IIS as Reverse Proxy with Automatic Certificate Renewal

[Justus 7]

I have just read the guide and it seems to be very good and interesting for many people. Since I want to set up my Emby server on a mini Windows PC that runs 24/7, I was also interested in it. But it seems to be much more complicated than what I have in mind. Can't I just take the normal Emby installation and use a Powershell script via Windows task scheduling? That then automatically retrieves the IP address of the server and compares it with the DNS-A-Record-IP stored with my domain provider. If there is a discrepancy, the script updates the A-record at the domain provider with the new IP address. Just schedule this every minute. The SSL certificate script by Certbot can also be entered in the Task Scheduler and be executed. 

And that's actually it, isn't it? What are the advantages of using 10 different applications in the guide? Security aspects or other things?
