The short version

  • Confluent Cloud is a managed Apache Kafka service billed.
  • containerd is free; Confluent Cloud starts at $385/mo.
  • Where Confluent Cloud falls short: requires understanding of eCKU (Elastic Confluent Unit) billing.
  • Where containerd falls short: not a developer-facing tool: there is no build command and the CLI is deliberately minimal, so it needs companions like nerdctl or Buildah.
  • Prices and features on this page were last checked on 13 November 2026.

Where each one falls short

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

Confluent Cloud

  • Requires understanding of eCKU (Elastic Confluent Unit) billing
  • Data in/egress costs add $0.014-$0.050 per GB
  • Storage costs of $0.03-$0.08 per GB-month
  • Minimum commitment recommended for cost optimization

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

containerd: Is containerd free?

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

Confluent Cloud: Is there a free tier for Confluent Cloud?

Yes, the Basic tier is free with one eCKU credit included. Additional usage is billed at $0.14 per eCKU-hour, plus data transfer and storage fees apply.

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.

Confluent Cloud: What additional fees does Confluent Cloud charge?

Beyond eCKU hours, Confluent charges data in/egress at $0.014-$0.050 per GB and storage at $0.03-$0.08 per GB-month. Costs vary by tier and region.

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.

Confluent Cloud: Does Confluent offer discounts for higher usage?

Yes, volume discounts are negotiated upfront based on annual consumption estimates. Annual commitments allow flexible cross-product allocation with guaranteed cost savings.

Source
containerd: Can containerd build images?

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