The short version

  • Each has a real cost: 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; Chef priced per node per year, at $59 on Business and $189 on Enterprise, so cost scales with fleet size rather than with team size

Where each one falls short

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

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

Chef

  • Priced per node per year, at $59 on Business and $189 on Enterprise, so cost scales with fleet size rather than with team size
  • Tripling the price between the two published tiers puts compliance and audit features well above basic automation
  • Enterprise Plus and every self managed deployment are custom quoted with no published price
