Managed OpenStack virtualization for sovereign cloud.

You can migrate in waves. Kumorion Virtualization can run alongside your existing environment during the transition, so you can move risk-tolerant workloads first and keep the option to reverse course. No big-bang cutover is required.

It depends on your environment — VM count, dependencies between systems and storage are the main drivers. We recommend starting with a pilot: it gives you a credible timeline based on your own data, and builds the internal business case at the same time.

Migration tooling handles the transfer, with a short cutover window per workload rather than a claim of magic zero downtime. Each wave has a rollback path, so a failed migration is not catastrophic. You get the tooling and the runbook, not a slogan.

We walk through what carries over and what gets rebuilt before anything moves. The fallback is plain: the source environment stays intact until each wave is verified, so nothing is lost if a wave needs to be repeated.

Yes, the equivalents exist: live migration, high availability, resource scheduling and host maintenance workflows are all part of the technology. Where behaviour differs from VMware, we say so. The automation layer handles the parts that are more manual in raw OpenStack.

Daily workflows barely change. Administrators and end users work through the standard OpenStack API and the Horizon web interface, including self-service for your own customers — so retraining needs are minimal and your product experience is protected.

In operator terms: lifecycle, upgrades and recovery become automated and repeatable instead of manual. The architecture supports ongoing Day-2 operations, not only the initial deployment.

You can start small and grow from there. Sizing follows actual usage — for example the High Water Mark model for cores — so cost tracks what you use rather than peak guesses. Scaling up does not mean re-architecting.

With artifacts, not claims: the Nokia reference environment (around one million CPU cores in operation), ISO 27001 certification underway on Kumorion's side, and architecture documentation your procurement team can cite. The scale proof answers the “open source is not enterprise” concern directly.

Ownership and jurisdiction, not features. Your own infrastructure, operated by a 100% Finnish-owned company with full control of the software, is a different position from a region owned by a US entity subject to US law. Data, operational and technological sovereignty are all in your hands — and it is a story you can resell to your own regulated customers.

The full picture matters: licence savings — over 65% seen in practice — plus the operations effort you no longer have to carry yourself.

The safety is open source, not a vendor. The technology is built on upstream OpenStack, so even if Kumorion disappeared, your environment keeps running on the same open technology. Kumorion has operated OpenStack at Nokia scale for 10+ years — this is a mature destination, not a science project. The dependency you are leaving is proprietary and priced at will; open source removes that lever.

You keep your data, your workloads and your environment — they were always yours. The stack is upstream open source, so you can continue on vanilla OpenStack; what you lose is Kumorion's automation layer. A low exit cost is exactly why you can commit now.
