The short version

  • Each has a real cost: containerd not a developer-facing tool: there is no build command and the CLI is deliberately minimal, so it needs companions like nerdctl or Buildah; 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
  • They diverge on capability: containerd covers Full container lifecycle, Microsoft Azure covers Virtual Machines.
  • 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.

containerd

  • Not a developer-facing tool: there is no build command and the CLI is deliberately minimal, so it needs companions like nerdctl or Buildah
  • Debugging is lower-level than Docker, and error messages assume knowledge of the runtime internals
  • Documentation is aimed at platform engineers, so newcomers usually find Docker or Podman material more useful
  • No image building at all — that is out of scope by design

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

Answered from the vendors’ own pages

containerd: Is containerd free?

Yes. It is an open-source CNCF graduated project with no licence fee.

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
containerd: Do I need containerd if I use Docker?

You already have it. Docker uses containerd underneath to run containers; it is not an alternative you install separately.

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
containerd: Why did Kubernetes drop Docker for containerd?

Kubernetes talks to runtimes through the Container Runtime Interface. Docker did not speak CRI natively and needed a shim, so Kubernetes removed the shim and talks to containerd directly, which Docker was already using anyway.

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
containerd: Can containerd build images?

No. Image building is deliberately out of scope. Tools such as Buildah, BuildKit or Docker handle that.
