The short version

  • Each has a real cost: GNAT Pro no pricing published on website; requires contacting AdaCore directly for quotes; Portworx bare metal nodes are charged at 1.11 USD per node hour against 0.33 for virtual nodes, so a bare metal cluster costs more than three times a virtualised one for identical capability.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

GNAT Pro

  • No pricing published on website; requires contacting AdaCore directly for quotes
  • Vendor indicates per-user, per-year subscription model but does not disclose specific costs

Portworx

  • Bare metal nodes are charged at 1.11 USD per node hour against 0.33 for virtual nodes, so a bare metal cluster costs more than three times a virtualised one for identical capability.
  • A 1,000 node hour monthly minimum applies, which means small or intermittent clusters pay for capacity they do not consume.
  • Replicating volumes across nodes consumes real capacity and network bandwidth, so the underlying infrastructure cost rises alongside the licence in a way the node hour rate does not show.
  • Pure Storage ownership means roadmap priorities are set by an array vendor, and buyers should confirm that hardware independence remains contractual rather than assumed.
  • Operating it well requires Kubernetes storage expertise, and teams that adopted Kubernetes to simplify operations often find they have added a distributed storage system to run.

Answered from the vendors’ own pages

GNAT Pro: How much does GNAT Pro cost?

GNAT Pro pricing is not published on the website. Customers must request a pricing quote by contacting AdaCore directly or speaking with a GNAT Pro expert.

Source
Portworx: Is Portworx tied to Pure Storage hardware?

No. It runs on any Kubernetes distribution over any underlying storage, though Pure has owned it since 2020 and sets the roadmap.

GNAT Pro: What is GNAT Pro licensing model?

GNAT Pro is sold on a per-user, per-year basis with no license locks. Customers can request pricing for their specific needs.

Source
Portworx: What does a real cluster cost?

At 0.33 USD per virtual node hour, twenty nodes running continuously is roughly 4,800 USD a month. Bare metal at 1.11 USD per node hour is around 16,000 USD for the same node count.

Portworx: Is backup included?

No. Portworx Backup is a separately priced product covering Kubernetes application backup.
