The short version

  • Only Rook has a free tier, so it costs nothing to try first.
  • Each has a real cost: IAR Embedded Workbench no pricing information published on product page; prospective customers directed to free trial or sales contact only; 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.
  • 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.

IAR Embedded Workbench

  • Embedded software development and debuggingnot Rook
  • Compiler and linker tools for embedded systemsnot Rook
  • Multi-architecture embedded development supportnot Rook

Rook

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

Where each one falls short

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

IAR Embedded Workbench

  • No pricing information published on product page; prospective customers directed to free trial or sales contact only
  • Pricing model not specified; customers must request quote or try free trial to understand licensing costs
  • Embedded development tools typically require expensive licenses, but specific IAR costs unavailable online

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

IAR Embedded Workbench: How much does IAR Embedded Workbench cost?

IAR Embedded Workbench pricing is not published on the product page. Prospective customers are directed to free trials or must contact the sales team to request pricing.

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.

IAR Embedded Workbench: Does IAR Embedded Workbench offer a free trial?

Free trials are available for IAR Embedded Workbench evaluation at https://www.iar.com/embedded-development-tools/free-trials, though specific trial length and limitations are not detailed on the product page.

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.

IAR Embedded Workbench: What is the pricing model for IAR Embedded Workbench?

The pricing model is not disclosed on the product page. Customers must contact the sales team to obtain quotes and understand licensing terms.

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.
