What do you self-host?

I'll start:

• Kubernetes
• Nextcloud
• Matrix-synapse
• Minecraft
• Authoritive DNS servers (powerDNS)
• Mail-servers (postfix, and Haraka)
• Peertube
• Writefreely
• GoToSocial (a small footprint fediverse server)
• CalcKey (fediverse software)
• My own small websites
• Some small bots
• Kubernetes
• VPN

The Hardware I use:

• A bunch of Dell Optiplexes, Proliant Microserver G8, Synology NAS, mikrotik switches.
• And a rack with a 100TB ceph cluster with some friends with a total of 700 cores and 4tTB RAM
