Multi-cloud Kubernetes, for fault tolerance
Our infrastructure stays agnostic: it combines our own servers and third-party capacity to absorb failures, while management and backups stay centralised.
Multi-cloud, for us, does not mean "deploy everywhere in one click". It means one precise, useful thing: not putting all your eggs in the same hardware basket, so that the failure of one site or one provider does not stop your service.
Bunker's infrastructure combines its own servers and instances rented from third parties, so as to spread the risk. Management of the cluster and backups, however, stay centralised: you keep a single control point, not an unmanageable mosaic.
What multi-cloud actually does with us
No magic promise. An architecture that spreads load and risk across several infrastructures, driven from a single place.
An agnostic infrastructure
The cluster is not married to a single provider. It combines our servers and capacity rented from third parties, for example to absorb a spike or keep a failover site active.
Fault tolerance
Spreading workloads across several sites and providers lets you absorb the failure of one of them without interrupting the service. That is the real benefit of the approach, before any marketing consideration.
Centralised management and backups
Workloads are spread, but control is not. Management of the cluster and backups stay centralised, so that spreading does not add operational complexity on your side.
Protected secrets, zero-trust network
Secrets are managed through a key management service (KMS) and access between components goes through a zero-trust network across all clusters. Opening up to several infrastructures does not come at the expense of isolation.
What our multi-cloud is not
Let us be clear to avoid any misunderstanding. We do not offer a magic button that would deploy your workloads simultaneously on AWS, Azure and Google Cloud. We do not resell a proprietary orchestrator that would mask the differences between providers either.
Our multi-cloud is a resilience architecture: servers of our own, third-party capacity where it makes sense, and centralised control. If your need is to spread workloads across several public clouds following a precise logic, let us talk and scope what is actually feasible for your case.

Frequently asked questions
What does multi-cloud mean at Bunker?
An agnostic infrastructure that combines our own servers and third-party instances to ensure fault tolerance, with centralised management and backups. The goal is resilience, not simultaneous deployment across every public cloud.
Do my workloads run on AWS, Azure or GCP?
Our foundation runs on our own servers and on capacity rented from European third parties for fault tolerance. We do not deploy your workloads on the US hyperscalers' clouds by default. If you have a specific constraint, we discuss it and scope what is feasible.
How is data backed up in multi-cloud?
Backups are centralised, on object storage internal to Bunker. Spreading workloads across several infrastructures does not scatter your backups: they stay driven from a single point, in Europe.
Does multi-cloud stay sovereign?
Yes. The third-party capacity we use stays within a European perimeter, and management as well as backups are operated by Bunker, a European company, with no subcontractor under US jurisdiction.
How do we avoid depending on a single cloud provider?
To avoid depending on a single cloud provider, three levers matter: an open standard like Kubernetes and an open-source stack that make your applications genuinely portable, tested reversibility with a documented exit runbook, and off-site backups paired with a written recovery plan. Dependence is fought by design, not by hoping the provider stays accommodating.
