The short version

  • Only OpenTelemetry has a free tier, so it costs nothing to try first.
  • Each has a real cost: OpenTelemetry genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right; 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: OpenTelemetry covers Vendor-neutral SDKs, Portworx covers Container-native volumes.
  • Prices and features above were last checked on 1 September 2026.

  • Standardising telemetry across services written in different languagesnot Portworx
  • Routing and filtering telemetry centrally to control observability spendnot Portworx

Portworx

  • Running a production PostgreSQL or Cassandra cluster on Kubernetes and needing the data to survive node lossnot OpenTelemetry
  • A platform team offering self-service databases to developers on an internal Kubernetes platformnot OpenTelemetry
  • Failing over stateful applications between clusters in different regions as a disaster recovery positionnot OpenTelemetry
  • An OpenShift estate where the built-in storage option does not meet the availability requirement for stateful setsnot OpenTelemetry

Where each one falls short

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

OpenTelemetry

  • Genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right
  • Language SDKs mature at different rates, so a polyglot estate gets uneven support
  • It produces and moves telemetry but does not store or visualise it, so a backend is still required and still billed

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.

Can I use OpenTelemetry for free?
Yes. OpenTelemetry has a free tier, so you can try it without paying. Portworx starts at $0.33/node hour.
What is OpenTelemetry best used for?
OpenTelemetry is most often used for instrumenting once and keeping the option to change observability vendor later, standardising telemetry across services written in different languages, routing and filtering telemetry centrally to control observability spend. Of those, instrumenting once and keeping the option to change observability vendor later and standardising telemetry across services written in different languages are not what Portworx is typically brought in for.
What can OpenTelemetry do that Portworx cannot?
OpenTelemetry covers Vendor-neutral SDKs, Collector, Three signals, Auto-instrumentation. Portworx covers Container-native volumes, Failure domain placement, Volume encryption, Database automation.

Answered from the vendors’ own pages

OpenTelemetry: Is OpenTelemetry free?

Yes, open source under the CNCF. What you pay for is the backend you export to.

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.

OpenTelemetry: Does OpenTelemetry replace Datadog or Grafana?

No. It replaces their proprietary agents and instrumentation libraries. You still need a backend to store and query the data.

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.

OpenTelemetry: Why adopt a vendor-neutral standard?

Because instrumentation is the expensive part. Once code emits OTel, changing observability vendor is a collector config change instead of re-instrumenting every service.

Portworx: Is backup included?

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