Mid 2022, a friend of mine helped me set up a selfhosted Vaultwarden instance. Since then, my "infrastructure" has not stopped growing, and I've been learning each and every day about how services work, how they communicate and how I can move data from one place to another. It's truly incredible, and my favorite hobby by a long shot.
Here's a map of what I've built so far. Right now, I'm mostly done, but surely time will bring more ideas. I've also left out a bunch of "technically revelant" connections like DNS resolution through the AdGuard instance, firewalls and CrowdSec on the main VPS.
Looking at the setups that others have posted, I don't think this is super incredible - but if you have input or questions about the setup, I'll do my best to explain it all. None of my peers really understand what it takes to construct something like this, so I am in need of people who understand my excitement and proudness :)
I saved this! Yeah, it seems like a lot of work, but I got inspired again (I had a slight self-hosting burnout and nuked my raspberry setup ~year ago) so I appreciate it. :) Can I ask what hardware you run this on?
edit: I just wanted to ramble some more: I just fired up my rPI4 again just last week, setup it with just as barebone VPS with wireguard, samba, jellyfin and pi-hole+unbound (as to not burn myself again :D )
My homelab runs on an N100 board I ordered on Aliexpress for ~150€, plus some 16GB Corsair DDR5 SODIMM RAM.
The Main VPS is a 2 vCPU 4GB RAM machine, and the LabProxy is a 4 vCPU 4GB RAM ARM machine.
I use Hetzner, mainly because of their good uptime, dependable service and being geographically close to me. Its a "safe bet" if you will. Monthly cost, if we're not counting power usage by the homelab, is about 15 bucks for all three servers.
