In-house development
Developed and built in Munich
The metalstack.cloud On-Prem Starter was conceived, built, and perfected by the metalstack.cloud team at x-cellent technologies in Munich.
The compact all-in-one rack was developed entirely in-house – from hardware design to software integration. The result: a fully functional private cloud test environment that enables companies to experience our technology hands-on and in real conditions.
A system we’re proud of – unique, reliable, and available exclusively from us.
Cloud freedom starts on premises
With metalstack.cloud On-Prem, you can operate your cloud infrastructure in your own data center—with full control, real hardware, and open technology. This creates true sovereignty: independent, secure, and “Made in Germany.”
Maximum data protection through physical isolation and dedicated firewalls.
Already aligned with regulatory requirements — and certifiable if needed.
Automation minimizes operational effort and costs. Open source ensures full transparency.
Operate without vendor lock-in – easily switch between platforms and environments when required.
