Enabling a sovereign european cloud
Use Case: Apeiro-RA Project
We work with SAP’s CobaltCore team to co-design a Kubernetes-based OpenStack distribution for enterprise and public sector use.
At its core is the Cyberus Hypervisor – an open-source, secure, and high-performance virtualization solution. Integrated with OpenStack-Nix, it enables reproducible, modular, and infrastructure-as-code cloud deployments.

Benefits
The benefits of our Hypervisor
Modular, secure, and high-performance by design—our hypervisor stack enables near-zero downtime updates, seamless integration, and near-native speed.
Modularity
- Pluggable Components
Swap or extend hypervisor services (scheduler, APIs, add-ons) on demand with near-zero downtime. - Layered Abstractions
Thin base OS + KVM kernel + cloud hypervisor stack keeps each layer independent and replaceable. - Integrator-Friendly
Well-documented interfaces let your team plug in custom logic or third-party tools in minutes.
Security (Rust)
- Memory-Safe Codebase
VMM written in Rust to eliminate classes of vulnerabilities (buffer overflows, use-after-free, etc.). - Auditable & Verifiable
Deterministic builds and clear module boundaries support code reviews, formal checks and compliance. - Cleared by Gemany's BSI
Same architecture underlies our VS-NfD approved variant, cleared by Germany's BSI for classified workloads.
Performance
- Near-Native Throughput
Minimal context switches deliver bare-metal-like I/O and CPU performance. - Elastic Resource Allocation
Rapid VM spin-up and real-time scaling ensure you only pay for exactly the resources you use. - Cache-Aware Scheduling
Intelligent placement keeps working sets hot and maximizes multi-tenant efficiency.
Cyberus Hypervisor architecture
The Core of our Cloud-Solution
Secure and Reliable Isolation
Runs cloud hypervisor in VMX root mode—minimizing attack surface without sacrificing performance.
API-First Orchestration
Unified VM scheduler + external APIs enable fully automated provisioning, scaling, and lifecycle management.
Clear Responsibility Model
Distinct “Cyberus vs. Integrator vs. Shared” ownership boundaries streamline integration and support.
