The short version

  • Only Rook has a free tier, so it costs nothing to try first.
  • Each has a real cost: OVHcloud public Cloud pricing table lists a scheduled price change with a column labeled Price on April 1, 2026, showing current rates are promotional and set to change on that date; Rook rook automates Ceph but does not abstract it, so an incident still demands Ceph expertise, and organisations without it end up hiring consultants at exactly the wrong moment.
  • They diverge on capability: OVHcloud covers Public Cloud, Rook covers Ceph operator.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

OVHcloud

  • Managed Kubernetes container orchestration for cloud-native applicationsnot Rook
  • Virtual machine instances with customizable CPU, RAM, and IOPSnot Rook
  • Object storage with S3-compatible API for scalable data archivalnot Rook
  • Managed databases including PostgreSQL, MySQL, MongoDB, and ClickHousenot Rook
  • Private network connectivity with vRack for multi-AZ isolationnot Rook

Rook

  • An on-premises Kubernetes platform needing block, shared filesystem and S3 storage without buying three productsnot OVHcloud
  • A team that already runs Ceph and wants its lifecycle managed declaratively inside Kubernetesnot OVHcloud
  • A large cluster where three-way replication overhead is unaffordable and erasure coding is requirednot OVHcloud
  • An organisation building a private cloud that cannot use managed cloud storage services for residency reasonsnot OVHcloud

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

OVHcloud

  • Public Cloud pricing table lists a scheduled price change with a column labeled Price on April 1, 2026, showing current rates are promotional and set to change on that date
  • Free network traffic and free Object Storage API calls exclude the Asia-Pacific region

Rook

  • Rook automates Ceph but does not abstract it, so an incident still demands Ceph expertise, and organisations without it end up hiring consultants at exactly the wrong moment.
  • There is no vendor and no SLA; the realistic commercial support routes are IBM Red Hat OpenShift Data Foundation or an independent Ceph consultancy, both of which change the cost picture entirely.
  • Ceph is resource hungry, needing substantial memory and dedicated disks per OSD, so the hardware cost of a properly sized cluster is often underestimated.
  • Recovery and rebalancing after a disk or node failure generates heavy background input and output that can degrade application performance for hours, which surprises teams sizing for steady state.
  • Minimum viable clusters require several nodes with several disks each, so it is impractical at small scale and the entry hardware cost exceeds simpler alternatives.

Answered from the vendors’ own pages

OVHcloud: How does OVHcloud charge for cloud services?

OVHcloud offers pay-as-you-go pricing for compute, storage, and bandwidth. Specific per-unit costs are accessed through the pricing calculator on the vendor site.

Source
Rook: Who supports it in production?

Nobody by default. IBM sells Red Hat OpenShift Data Foundation, which is supported Rook and Ceph, and independent consultancies sell Ceph support. Decide this before deployment.

OVHcloud: Are there savings plans for OVHcloud services?

OVHcloud mentions savings plan options on its services pages, but pricing discounts and commitment terms are not detailed on the homepage.

Source
Rook: Does it need Ceph knowledge?

Yes. Rook handles deployment and routine operations, but troubleshooting a degraded cluster is a Ceph skill and there is no way around it.

OVHcloud: What is the cost of OVHcloud zero inter-AZ fees?

OVHcloud advertises zero inter-AZ (availability zone) fees for data transfers within its network. Monthly subscription rates for individual services are not published on the vendor homepage.

Source
Rook: Can it replace an object storage appliance?

Functionally yes, through the RADOS gateway, but you take on the operations that an appliance vendor would otherwise carry.
