OVHcloud Object Storage

OVHcloud Object Storage is the S3-compatible object store from the French provider OVH Groupe, reached at a single endpoint per region with SigV4 signing, so existing clients, SDKs and backup tools point at it by changing an endpoint rather than rewriting code.

The commercial argument is what is not metered. OVHcloud’s own product page states there are “no charges for API calls, incoming traffic, or outgoing traffic” — you pay for stored capacity and, on the archive classes, for restores. Against S3, where egress is billed per gigabyte and PUT, GET and LIST are each metered, that removes the two line items that make an object-storage bill hard to predict. Storage classes run from High Performance on NVMe through Standard and Infrequent Access down to Cold Archive on tape, with lifecycle rules to move objects between them. Of thirteen regions, eight are in Europe — Gravelines, Roubaix, Strasbourg, Frankfurt, London, Warsaw, Paris and Milan — and parts of the estate carry ANSSI SecNumCloud qualification, which no American hyperscaler can offer a French public buyer.

The gaps are specific and worth knowing before a migration. OVHcloud’s published S3 compliance table marks “put bucket notification configuration” as unsupported, so the S3-event-triggers-a-function pattern has no counterpart here. S3-style JSON bucket policies are also unsupported in the standard regions, which means access rules written as policies have to be re-expressed as ACLs plus OVHcloud IAM. SSE-KMS, Intelligent-Tiering and Block Public Access are likewise absent. Versioning, object lock with legal hold and retention, lifecycle configuration, CORS, presigned URLs, multipart upload and async replication are all present.

The operating company is OVH SAS, a société par actions simplifiée with EUR 50,000,000 of capital at 2 rue Kellermann, 59100 Roubaix, RCS Lille Métropole 424 761 419, VAT FR 22 424 761 419. It is a subsidiary of OVH Groupe SA, RCS Lille 537 407 926, the listed holding company at the same address, registered in October 2011 under the holding NAF code 64.20Z. Octave Klaba founded the business in 1999 and the French register records him as chairman of the board and chief executive; Henryk and Miroslaw Klaba also sit on it.

Family control is not in doubt. At 5 December 2025 the Klaba family — Henryk, Octave, Miroslaw and Halina, plus entities they control — held 79.0% of the capital and 79.6% of the voting rights; employees, executives and directors held 1.8%, treasury shares 0.8%, and the free float 18.4% of 151,651,536 shares. The group reported EUR 1,085 million of revenue and EUR 438 million of adjusted EBITDA for FY2025, with 1.6 million customers and around 3,000 employees, and guides to 5-7% like-for-like growth for FY2026.

OVHcloud designs and manufactures its own servers and builds its own data centres, a vertical integration it credits for its price-performance, and it cools them with water of its own design. It counts 46 data centres on four continents, roughly 500,000 servers, 31 Local Zones, 44 redundant points of presence and 100 Tbps of backbone capacity, with a network of 150 mini-datacentres planned by the end of 2027. Its Bare Metal Pod, SecNumCloud Private Cloud and SNC Cloud Platform carry the SecNumCloud qualification from ANSSI, the French state’s highest cloud trust level, which is the thing no American hyperscaler can offer a French public buyer.
