Our cloud method

Sovereign cloud option

Public, private, sovereign Europe or hybrid. We pick the target adapted to your regulatory constraints.

FinOps from day 1

Target budget defined before migration, cost monitoring, automatic alerts. No bad surprises.

Refactoring when useful

Lift-and-shift isn't always the right choice. We qualify each app: rehost, replatform or refactor.

Frequently asked questions

No. European sovereign cloud (Scaleway, OVH, UpCloud, Infomaniak) is mature for 80% of cases and solves GDPR concerns. We also offer private / hybrid.

From 3 months (SMB, 10-20 simple apps) to 18 months (enterprise, 100+ apps with refactoring). Initial scoping gives a realistic estimate.

FinOps from day 1: target budget, strict tagging, initial rightsizing, savings plans / committed use and continuous monitoring. We make it a mandatory deliverable.
