What got you into selfhosting and what was the first thing that you hosted?
For me, it was PhotoPrism. I used to be an idiot, and used Google Photos as my gallery. I knew that it was terrible for privacy but was too lazy to do anything about it. When Google limited storage for free accounts, I started looking for alternatives. Tried out a lot of stuff, but ended up settling on PhotoPrism.
It does most things that I need, except for multiple user support (it's there in the sponsored version now). It made me learn a bit about Docker. Eventually, I learned how to access it from outside of my home network over Cloudflare tunnel. I'm happy that I can send pics/albums to folks without sharing it to any third party. It's as easy as sending a link.
Now I have around a dozen containers on a local mini pc, and a couple on a VPS. I still route most things through Cloudflare tunnels (lower latency), only the high bandwidth stuff like Jellyfin are routed through a wireguard tunnel through the VPS.
Anyway, how did you get into selfhosting? (The question is mostly meant for non-professionals. But if you're a professional with something interesting to share, you're welcome as well.)
For me it was ages ago (probably 2006), I was starting to learn about virtualization so I got a cheap server on ebay and started with VMWare ESX. I then virtualized Asterisk PBX and self hosted that for about 10 years, and an open source radio automation software named Rivendell Radio Automation, I self hosted 2 Internet radio stations for about 5 years since 2008, and had a small studio at home (before all the podcast kits that became very common a few years later).
I moved to the cloud for a bit while working at a big cloud provider that offered us a lot of free credits, but I'm back to having servers at home and hosting my media collection, some services my family uses and a lot of learning labs.
Yep, it was my door to working at a terrestrial radio conglomerate as the IT manager and having a small technology segment on-air daily. It was good times!
I started by self-hosting an autoDJ to pipe music into Second Life, later did a weekly show on a tiny internet radio station for maybe 18 months ... trying to make a name in order to get a DJ spot on-air at a local community radio station that was indie/alt-rock format at the time. Sadly my life took a turn and the community station changed hands and changed formats, but it was a cool experience nonetheless!
