Things are really getting easier nowadays.

2 years ago I deployed the backend of this website on a VPS, even though the backend itself is simply brought up by docker compose, I still had to do a whole bunch of nginx reverse proxy setup manually, and then paying Hetzner cloud 10 euros per month for the instance.

But finally I brought a raspberry pi 4B from home (which hasn't been used for a long time) and setup the same system with Cloudflare tunnel, it does the job perfectly and I don't need the VPS instance anymore
