Why Exaion for Private Cloud?

The use of public clouds raises serious concerns for organizations that manage sensitive, regulated, or mission-critical data. With unpredictable licensing costs, dependency on a handful of major cloud providers, and stringent regulations such as DORA, NIS2 and GDPR, firms are being forced to reconsider where and how their most important data is stored.

Exaion provides an alternative: a completely open-source, on-premises or dedicated private cloud that restores control — without having to rebuild everything from scratch.

1

You stay in full control

Keep your autonomy, resilience and high performance

  • Control plane on your premises
  • Source code delivered to you, fully auditable and patchable by your own staff
  • Zero Exaion visibility into your data
  • You can't be cut off unexpectedly

In other words: if you can’t audit it, remove it, or operate it without the internet, then it doesn’t truly belong to you. Exaion’s system passes all three tests.

Open-source, no lock-in

Exaion’s entire IaaS/PaaS layer is built on open-source technology (OpenStack, Kubernetes, Ceph) not a proprietary layer with an open-source veneer.

  • No hidden licenses, no forced bundling, and no vendor lock-in
  • 10+ open-source LLMs available, plus bring-your-own-model (BYOM) support
  • Switch models or components without reconfiguring your applications
  • Existing workloads run unchanged; new services are cloud-native from day one

Proprietary virtualisation licenses have risen in price by 150% to 500% since 2024, and some by more than 1,000%. A greenfield, open-source foundation insulates you from that inflation.

Built for regulated and sensitive environments

Exaion is purpose-built for organizations that cannot compromise on data control. It was originally developed within French energy giant EDF, so the constraints of critical-infrastructure operations are in our DNA — an understanding few cloud providers can match.

Regulated industries

DORA, NIS2, HDS and GDPR compliance built in, with 100% auditable data residency.

Healthcare & pharma

HDS-compliant hosting for health data, GxP-aligned workflows, and full residency for clinical and R&D workloads.

Defence & sensitive manufacturing

Air-gapped operation, ZRR (“Secret Défence”) compatibility, and physical and logical resource isolation.

Financial services

Dedicated, non-shared resources with guaranteed SLAs.

Critical infrastructure & energy

On-prem GPU inference, real-time digital twins, and edge deployment close to operational assets.

Reliable costs and a quicker rollout

Cloud costs shouldn’t keep changing. Exaion uses capacity-based, fixed-rate billing, so you get a budget you can plan for over a 3-to-5-year period rather than facing unexpected price increases later on.

  • Up and running in 6–12 months; quicker than sovereign infrastructure
  • Detailed usage reporting to support internal chargeback and billing
  • Optimised, right-sized hardware sourcing that lowers total cost of ownership
5

Resilience that doesn’t depend on the internet

Exaion’s private cloud can operate in full air-gapped mode and keeps working even if the connection is lost, something no hyperscaler is able to provide. Coupled with a distributed, multi-site architecture, it ensures operational continuity for the workloads that matter most, wherever they run: on a factory floor, at a trading desk, or in a classified research environment.

Proven at scale, backed by serious partners

Exaion already runs over 1,250 GPUs and 37 petabytes of storage across four data centres, with a 99.9% availability rate and 24-hour technical support.
