Self-hosting services

I like self-hosting my own services to have complete control over them, below you can find a list of services I self-host.

Nextcloud + Collabora: This is probably one of the first one I've been hosting. I'm using it for file storage, Obsidian notes, calendar, contacts.
Matrix: An decentralised encrypted chat platform, I mostly use it to contact some friends. For configuration I use Matrix Ansible.
DNS Nameservers: Some of my domains I own are served by my own DNS-system. There are currently three separate PowerDNS servers on my cloud servers serving about a dozen domains.
Mail server: I'm hosting my own mail server, currently it is using Mailcow, I did previously use Mail-in-a-box.
Various others: I have some others too (Minecraft, Home Assistant, Influx, Gitea) but they are not as interesting as the ones above.
