The short version

  • Each has a real cost: 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.; Vultr vultr Cloud Compute pricing as captured 31 December 2022 started at $5/month (1 vCPU, 1GB RAM, 25GB storage, 1TB transfer), scaling to $10/month and $20/month with more vCPU/RAM/storage; bandwidth overage billed at $0.01 to $0.05 per GB depending on plan
  • They diverge on capability: Rook covers Ceph operator, Vultr covers Cloud servers.

Where each one falls short

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

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.

Vultr

  • Vultr Cloud Compute pricing as captured 31 December 2022 started at $5/month (1 vCPU, 1GB RAM, 25GB storage, 1TB transfer), scaling to $10/month and $20/month with more vCPU/RAM/storage; bandwidth overage billed at $0.01 to $0.05 per GB depending on plan

Questions people ask

Is Rook or Vultr better?
Neither clearly leads. Rook starts at Free and Vultr at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Rook or Vultr?
Rook starts at Free and Vultr at Free.
Does Rook or Vultr run on more platforms?
Rook runs on Linux, Kubernetes. Vultr runs on Web, Api, Cli.
Can I use Rook for free?
Both have a free tier, so you can try either at no cost before committing.
What is Rook best used for?
Rook is most often used for an on-premises kubernetes platform needing block, shared filesystem and s3 storage without buying three products, a team that already runs ceph and wants its lifecycle managed declaratively inside kubernetes, a large cluster where three-way replication overhead is unaffordable and erasure coding is required, an organisation building a private cloud that cannot use managed cloud storage services for residency reasons. Of those, an on-premises kubernetes platform needing block, shared filesystem and s3 storage without buying three products and a team that already runs ceph and wants its lifecycle managed declaratively inside kubernetes are not what Vultr is typically brought in for.
What can Rook do that Vultr cannot?
Rook covers Ceph operator, Block, file and object, Erasure coding, CSI driver. Vultr covers Cloud servers, Bare metal servers, Block storage, Object storage.

Answered from the vendors’ own pages

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.

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.

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.
