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
Indeed it is! I remember a big change in resource-use between 1.18 and 1.22. And it is even less now. My server has joined many big rooms and it is doing great on 1 core and 1gb ram (even thou I have allocated more to it).
