STACKIT is the cloud platform of Schwarz Group (Lidl, Kaufland) — the largest German hyperscaler initiative. With data centers in Heilbronn (operational) and Lübbenau (under construction, €11B investment), STACKIT targets sovereign cloud solutions for authorities and regulated industries. The BSI has been cooperating with Schwarz Digits since 2025.

Native STACKIT services use OpenStack-based Kubernetes/IaaS. Proxmox on STACKIT additionally provides KVM virtualization with full hardware control, simpler VM management and no vendor lock-in — you can migrate the Proxmox stack to another provider anytime.

Yes, significantly. STACKIT is positioned in the premium segment (comparable to Microsoft Cloud Germany). The premium pays off with compliance requirements that Hetzner does not fulfill: BSI C5, KRITIS, BaFin, government certifications. In consulting we clarify whether STACKIT is economically sensible for you.

Schwarz Digits is the IT subsidiary of Schwarz Group (Lidl, Kaufland) and operates STACKIT as German hyperscaler. Unlike US hyperscalers, Schwarz is not subject to foreign jurisdiction — no CLOUD Act exposure, no FISA requests.

Yes. Since we use Proxmox VE (open standard), your VMs can be migrated to another Proxmox cluster at Hetzner, OVH, IONOS or on-premise anytime. You have no vendor lock-in — that's a central advantage over native cloud services.

STACKIT compute and storage costs come directly from STACKIT — priced in the AWS/Azure range. Our managed service on the Proxmox layer: from €99.90/month (standard SLA). A complete cost framework comes after the architecture workshop.
