Sovereign cloud — migration, FinOps, DR, multicloud

A cloud that breathes with your business — sovereign by default, hybrid if needed, FinOps from start to finish.

01 · Pillar

Proprietary sovereign cloud

Our [sovereign datacenter](/en/infrastructure/datacenter/) is multi-site in France (Île-de-France and Occitanie, HDS-certified) and operated by our teams. No extra-European third party, no telemetry leaving the EU.

02 · Pillar

Cloud migration

Scoping, eligibility study, migration plan, wave-by-wave execution, change management. Lift-and-shift, replatforming or refactoring depending on criticality and ROI.

03 · Pillar

FinOps and cloud governance

Real-time cost tracking, tagging, drift alerting, reserved instances and savings plans. Monthly reports readable by your CFO.

04 · Pillar

Tested DR and BCP

Disaster recovery plan and business continuity plan documented and exercised twice a year. RPO and RTO contractual, not just promised.

05 · Pillar

Multicloud and hybrid

AWS, Azure, GCP, OVHcloud, Scaleway. Combined with your on-premise or our sovereign datacenter — no hard lock-in to a single provider.

Sovereign cloud — without giving up control

Cloud is not an end in itself: it is a lever for agility, resilience and FinOps. But when your data crosses three continents and four subcontractors, you lose control. Hexceos operates a proprietary cloud in France for workloads that must stay there, and supports — with rigour — your deployments on AWS, Azure, GCP, OVHcloud or Scaleway.

What we cover

  • Hexceos sovereign cloud — VM, containers, databases, object storage, HDS hosting.
  • Hyperscalers — AWS, Azure, GCP with GDPR-aligned architecture and BYOK.
  • European cloud — OVHcloud, Scaleway, Outscale.
  • Hybrid — interconnect between Hexceos datacenter / public cloud / on-premise.
  • DR / BCP — sizing, implementation, biannual exercises.

Service commitments

  • Documented and auditable architectures before deployment.
  • Monthly FinOps reporting with quantified recommendations.
  • Contractual reversibility — your data, your configurations, your backups.
  • Contractual SLA per environment (production, pre-prod, dev).
FAQ

Questions
we get asked.

Do your hosting offers respect French sovereignty?
Our proprietary datacenter is in France (Île-de-France and Occitanie), operated by Hexceos employees, HDS-certified. No transfers out of the EU, no extra-European party in the critical chain. For workloads that must stay on a hyperscaler, we apply confidentiality architectures (end-to-end encryption, BYOK, strict segmentation).
Can you migrate our IT estate to the cloud without downtime?
Yes, in the vast majority of cases. We plan migration by waves, with progressive cutover, regression testing, short switch windows (often overnight or over a weekend), and a documented rollback plan. No customer has suffered data loss since 2022.
How much does a DR plan cost?
Cost depends on the expected RPO and RTO, on data volume and on application criticality. For an SMB, a classical DR (RPO 1h, RTO 4h) typically costs 1 to 4% of the annual IT spend. We provide precise pricing after scoping.
Do you work with AWS, Azure, GCP?
Yes. Hexceos supports workloads on hyperscalers (AWS, Azure, GCP) and on European actors (OVHcloud, Scaleway) and on our own datacenter. We tailor architecture to criticality, compliance and budget — not to a commercial partnership.
