Sponsored Session: Freedom to Build: Open Source Foundations for Sovereign Cloud Infrastructure

on YouTube ↗31m

" summary

Claims that a sovereign cloud can be built from open source are backed by a live setup: a two-node K3s cluster spanning Proxmox and Harvester hypervisors, running VMs and containers, serving an on‑prem Nextcloud with Longhorn storage and showing a file upload that succeeds. The stack uses Harbor registry for OCI images and Prometheus + Grafana for observability. Talk notes concrete tooling, cost and vendor‑lock reduction, and admits practical gaps: local operator skills and project sustainability remain the main obstacles.
