Kubernetes in your datacenter, your data on your premises
Run your containers on your own servers, in Europe, under your control. We install and operate a standard Kubernetes cluster on your premises, without your data ever leaving your walls.
On-premise Kubernetes is a cluster installed in your own datacenter or on your own hardware, rather than on a provider's cloud. Your containers, volumes and backups stay physically on your premises.
For regulated data, a hospital, a public body or a company that will not depend on an external cloud, this is often the only acceptable architecture. Bunker designs the offer and our Kubernetes infrastructure partner deploys then operates the cluster remotely, with the same open-source Kubernetes as everywhere else.
What on-premise brings you
Your data does not leave
Containers, storage and backups live on your hardware, on your premises or in your datacenter. No data transits through a third-party cloud. For regulated hosting or sensitive information, this is the strongest guarantee.
Control without the on-call burden
You keep physical control of the infrastructure, yet you do not have to recruit a Kubernetes team. The cluster is deployed, monitored and kept up to date remotely. You focus on your applications.
A cost amortised over time
Your hardware is an investment you amortise over several years, with no usage bill that climbs with the load. For a stable, lasting workload, the total cost becomes far more predictable than a usage-billed cloud.
Standard Kubernetes
No proprietary layer. Your team finds the project's standard tools again (kubectl, Helm, the usual operators) and your workloads stay portable if you change hosting one day.
Who on-premise makes sense for
On-premise hosting becomes necessary when data cannot leave: health records, public-body data, industrial property, information classified by a sector framework. It also appeals to organisations that already own a datacenter and want to make it pay, or that want to cut their dependence on a public cloud whose bill is drifting.
Kubernetes brings to these environments what classic on-premise often lacked: automated deployment, scaling, disaster recovery and modern operations, without giving up physical control.
On-premise, bare metal, cloud: how to choose
On-premise answers the question of place: your data stays on your premises. Bare metal answers the question of the layer: Kubernetes straight on the server, with no hypervisor, for performance and cost. The two often combine, since an on-premise cluster can run on bare metal.
If you have no server room, the same dedicated cluster can be hosted in a European datacenter. We help you decide based on your data, budget and team constraints, from your real situation.

Frequently asked questions
What is the difference between on-premise Kubernetes and a public cloud?
With a public cloud, your containers run on a provider's infrastructure, billed per use. On-premise, the cluster is installed on your own hardware, on your premises or in your datacenter, and your data never leaves your walls. You keep physical control of the infrastructure.
Do I need a Kubernetes team in-house?
No. The cluster is deployed and operated remotely by our Kubernetes infrastructure partner: monitoring, updates, security patches. Your team focuses on its applications and uses the standard Kubernetes tools, without having to operate the cluster itself.
Can on-premise be linked to a sovereign cloud?
Yes. Many organisations keep their sensitive data on-premise and burst the rest onto a European sovereign cloud to absorb peaks. The same Kubernetes foundation makes this hybrid architecture consistent end to end.
What if I change my mind later?
The cluster runs on standard Kubernetes. Your manifests and Helm charts are portable to a datacenter, another host or a sovereign cloud. You are never locked into a proprietary format.
