The short version

  • Each has a real cost: Northflank pricing complexity with multiple rate dimensions; 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: Northflank covers Application deployments, 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.

Northflank

  • Deploying AI inference models with GPU accelerationnot Rook
  • Running training workloads on distributed GPUsnot Rook
  • Building microservices with multi-cloud reliabilitynot Rook

Rook

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

Where each one falls short

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

Northflank

  • Pricing complexity with multiple rate dimensions
  • GPU costs can be expensive for large-scale deployments
  • Learning curve for Kubernetes concepts

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

Northflank: What is included in the free Sandbox tier?

The Sandbox includes always-on compute, 2 free services, 1 free database, 2 free cron jobs, and is perfect for testing applications.

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.

Northflank: How much does CPU cost on Northflank?

CPU costs $0.01667 per vCPU per hour on pay-as-you-go pricing.

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.

Northflank: What GPUs are available?

GPU options include NVIDIA L4 at $0.80/hr through H100 at $2.74/hr.

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.
