Own projects
Private cloud
It all began in 2016 with "ownCloud", running on a ThinClient with Debian 8 (Jessie) as the operating system, featuring a simple Apache web server and MySQL database.
Today, "Nextcloud" is running with MariaDB in a Docker environment on a Terra Server System equipped with an Intel Xeon CPU, hardware RAID, and Ubuntu Server (22.04 LTS) as the operating system. System backups are stored on a QNAP NAS with RAID configuration, as well as on externally hosted storage.
The environment is operated behind a hardware firewall with OPNsense as the operating system in its own DMZ.
Minecraft Server [Java]
For relaxation and building with the family, I have my own Minecraft server. It was initially started in 2011 with Beta 1.7.2 as a native server. Shortly thereafter, it was set up with Bukkit for mods and plugins.
Since the beginning of 2024, it has been running on version 1.20.1 with Forge plugins, offering more possibilities and fun. It's set up in a Docker environment for high flexibility and easy data backup.
