The short version

  • Only Ansible has a free tier, so it costs nothing to try first.
  • Each has a real cost: Ansible the open source project gives the engine and the language; the automation controller, automation mesh, automation hub, analytics and governance all belong to the paid Red Hat Ansible Automation Platform; Datadog consumption-based pricing model makes costs hard to predict and can scale quickly
  • They diverge on capability: Ansible covers Playbooks, Datadog covers Infrastructure monitoring.

Where each one falls short

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

Ansible

  • The open source project gives the engine and the language; the automation controller, automation mesh, automation hub, analytics and governance all belong to the paid Red Hat Ansible Automation Platform
  • Event-Driven Ansible and the AI coding assistant are platform features rather than open source ones
  • Red Hat does not publish platform pricing
  • Running open source Ansible at scale means building the control plane the platform otherwise provides

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
