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
They server my domains and 100 other domains, one of the also act as a slave/secondary DNS server for others who wish to use it.
