Self-hosting static or almost-static websites is now really easy with a Cloudflare front. I just closed my account on SmugMug and published my images locally using my NAS; this costs no extra money (is basically free) since the photos were already on the NAS, and the NAS is already powered on 24-7.
The NAS I use is an Asustor so it's not really Linux and you can't install what you want on it, but it has Apache, Python and PHP with Sqlite extension, which is more than enough for basic websites.
Cloudflare free is like magic. Response times are near instantaneous and setup is minimal. You don't even have to configure an SSL certificate locally, it's all handled for you and works for wildcard subdomains.
And of course if one puts a real server behind it, like in the post, anything's possible.
