Sovereign Cloud on Open Source: The Proxmox Case
Mid-market customers don't need a hyperscaler's catalogue. They need compute, backup and storage they can trust — hosted at home.
The gap in the middle
Organisations often choose between overseas hyperscalers and on-premise hardware they struggle to run. In between sits a large, underserved market: businesses that want reliable compute, backup and disaster recovery, with data kept in-country and support in their own time zone.
Why Proxmox
Proxmox VE delivers KVM virtualisation, clustering, live migration and a full API without licensing that punishes growth. Licence spend becomes engineering investment. Enterprise support subscriptions exist — and for production clusters, they are worth taking.
Start narrow, scale honestly
Launch with three things done well: VM cloud, backup/DR and object storage. Begin with a small high-availability cluster behind redundant firewalls, then grow toward Ceph for distributed storage and Kubernetes for containers when demand — not ambition — justifies it.
Sovereignty is an architecture decision
Data residency is not a marketing line. It is where the disks sit, who holds the keys and which jurisdiction governs access. Design it in, document it, and let regulated customers audit it.
The trade-off, stated plainly
Open source shifts cost from licences to people. You need engineers who can run storage, upgrades and incident response around the clock. If you cannot staff that, buy support — or buy the managed alternative. Pretending otherwise is how outages are scheduled.
