The short version

  • Each has a real cost: Microsoft Azure the 12 months of free services is available only to new customers who have not previously had an Azure account or received 12 months of free services; OpenTelemetry genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right
  • They diverge on capability: Microsoft Azure covers Virtual Machines, OpenTelemetry covers Vendor-neutral SDKs.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Microsoft Azure

  • The 12 months of free services is available only to new customers who have not previously had an Azure account or received 12 months of free services
  • The 12 months free offer is not available to customers who sign up directly for pay as you go in China and India
  • Customers who try Azure free must move to pay as you go within 30 days to keep receiving the 12 months of free services
  • Free services are capped at specified monthly amounts, and only some of them are always free

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

Answered from the vendors’ own pages

Microsoft Azure: How much does Microsoft Azure cost?

Azure uses consumption-based pricing where you pay only for resources used and scale as you grow, with no fixed monthly fee. Prices are listed in USD globally, and pricing varies by service, region, and usage patterns.

Source
OpenTelemetry: Is OpenTelemetry free?

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

Microsoft Azure: How can I save money on Azure services?

Azure offers savings up to 65% on select compute services through Azure Savings Plans with one- or three-year commitments. Using Azure Hybrid Benefit with existing Windows Server and SQL Server licenses plus reservations can save up to 85% compared to standard rates.

Source
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.

Microsoft Azure: Does Azure offer a free tier?

Azure provides free tier services for new users and perpetually free options, including free Spot Virtual Machines, dev/test pricing for development workloads, and access to the Azure Pricing Calculator to estimate monthly costs before deployment.

Source
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.
