# Exaion Trusted Private Cloud

> A practical guide to trusted private cloud from Exaion: where the market is heading, what it means for your sector, and which type of private cloud (dedicated off-prem or on-premises) meets your needs. Exaion provides a fully open-source, sovereign private cloud for organisations that handle sensitive, regulated or mission-critical data.

Exaion was originally developed within the French energy group EDF. Its IaaS/PaaS layer is built entirely on open-source technology (OpenStack, Kubernetes, Ceph), with no proprietary licences or vendor lock-in. Key facts:

- Deployment: on-premises (control plane on the customer's site) or dedicated off-prem; can run fully air-gapped, with no dependency on internet connectivity
- Control: source code delivered to the customer, fully auditable and patchable; zero Exaion visibility into customer data
- Compliance: DORA, NIS2, HDS and GDPR built in, with 100% auditable data residency; ZRR ("Secret Défense") compatible
- AI: 10+ open-source LLMs available, plus bring-your-own-model (BYOM) support
- Pricing: capacity-based, fixed-rate billing, predictable over 3 to 5 years
- Timeline: typically 6 to 12 months from scoping to industrialisation (scoping, proof of concept, production pilot, multi-site rollout)
- Scale: 1,250+ GPUs in production, 37 PB of storage, 4 data centres, 99.9% availability, 24/7 technical support
- Sectors served: financial services, healthcare and pharma, defence and sensitive manufacturing, critical infrastructure and energy, and other regulated industries
