The short version

  • 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; Azure Functions consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that

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

Azure Functions

  • Consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that
  • The newer Flex Consumption plan's free grant is smaller still, at 250,000 executions and 100,000 GB-seconds per month
  • Premium plan avoids per-execution charges but bills continuously for allocated core seconds and memory regardless of invocation volume
  • Memory is rounded up to the nearest 128 MB and execution time to the nearest 1 ms for billing, so small overages round upward
