The short version

  • Each has a real cost: Puppet no pricing published for commercial tiers; requires contacting sales; 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: Puppet covers Manifests, Rook covers Ceph operator.
  • Prices and features above were last checked on 1 September 2026.

Rook

  • An on-premises Kubernetes platform needing block, shared filesystem and S3 storage without buying three productsnot Puppet
  • A team that already runs Ceph and wants its lifecycle managed declaratively inside Kubernetesnot Puppet

  • An organisation building a private cloud that cannot use managed cloud storage services for residency reasonsnot Puppet

Where each one falls short

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

Puppet

  • No pricing published for commercial tiers; requires contacting sales
  • Enterprise and Advanced tiers require custom quote
  • Free tier limited to 25 nodes maximum

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

Puppet: How much does Puppet cost?

Puppet's Developer tier is free for up to 25 nodes. Commercial, Enterprise, and Advanced tiers require contacting their sales team for a custom quote.

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.

Puppet: Is there a free version of Puppet?

Yes, Puppet's Developer tier is free forever for up to 25 nodes of infrastructure.

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.

Puppet: What does the Enterprise tier include?

Puppet's Enterprise tier includes web GUI, RBAC, and multi-environment support for organizations managing infrastructure at scale, with pricing available upon request.

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.
