I'd like to set up a personal cloud, probably through a vps to start. However, I'd also like to move my domains to the same server. It's been well over a decade since I did any server admin style work, so in technology years I'm old as feck.

What are my best options to look into as far as privacy/security/reliability/price for a vps? What are my best options to allow friends and family to mindlessly backup their data to our private cloud (if such a thing exists)? I'm looking for cross platform support and the ability to host multiple websites.
