Linode has some cool “turnkey” solutions for this. One example: https://www.linode.com/marketplace/apps/nextcloud/nextcloud/

So instead of doing a reverse proxy or vpn on self hosted hardware you would be renting linode servers that are already connected. Then you just have to follow the instructions to hook up a domain or add the relevant dns records.

Either way is fine it just depends on what you’re comfortable with and what you have on hand/want to buy.

And it is probably the coolest one for the rest of our lives.
