  • Each has a real cost: Buildah linux only, with no native macOS or Windows support; Datadog consumption-based pricing model makes costs hard to predict and can scale quickly
  • They diverge on capability: Buildah covers Daemonless builds, Datadog covers Infrastructure monitoring.

Where each one falls short

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

Buildah

  • Linux only, with no native macOS or Windows support
  • Scriptable builds are powerful but less portable and less familiar than a Dockerfile
  • Narrow by design: it builds images and does not run them, so it needs Podman or another runtime alongside

Datadog

  • Consumption-based pricing model makes costs hard to predict and can scale quickly
  • Add-on modules significantly increase costs: custom metrics, indexed spans, extended retention
  • No free tier for production monitoring
  • High costs for organizations with large amounts of log data or high-cardinality metrics
