The short version

  • Only Kubernetes has a free tier, so it costs nothing to try first.
  • Each has a real cost: Kubernetes complex initial setup and configuration with multiple interdependent components; 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.
  • They diverge on capability: Kubernetes covers Container orchestration, Portworx covers Container-native volumes.
  • 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.

Kubernetes

  • Complex initial setup and configuration with multiple interdependent components
  • Significant resource requirements for both hardware infrastructure and specialized human expertise
  • Expensive specialized talent in Kubernetes domain; hiring costs prohibitive for many organizations
  • New security challenges around container isolation and network security requiring robust measures
  • Requires continuous maintenance and updates to stay current with releases and security patches

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

Kubernetes: What is Kubernetes used for?

Kubernetes is a container orchestration platform that automates deployment, scaling, and management of containerized applications across clusters of machines.

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.

Kubernetes: Is Kubernetes free?

Yes, Kubernetes is free, open-source software maintained by the Cloud Native Computing Foundation. However, running Kubernetes clusters requires infrastructure investment.

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.

Kubernetes: How hard is it to learn Kubernetes?

Kubernetes has a steep learning curve. It requires deep knowledge of containerization, networking, and distributed systems. Teams without prior container experience should expect significant training time.

Source
Portworx: Is backup included?

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