The short version

  • Only Azure Functions has a free tier, so it costs nothing to try first.
  • 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; OneTrust complex usage-based pricing model with multiple meters (admin users, inventory size, daily visitors, data subjects) making total cost unpredictable

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

OneTrust

  • Complex usage-based pricing model with multiple meters (admin users, inventory size, daily visitors, data subjects) making total cost unpredictable
  • No published pricing examples or per-unit costs; all pricing requires custom quotes
  • Each solution area uses different pricing metrics, requiring complex calculations for multi-solution purchases
  • Enterprise-only positioning (Fortune 500 focus) suggests premium pricing, discouraging mid-market or startup adoption
  • Platform complexity and multiple solution areas may result in significant implementation and ongoing costs not disclosed upfront
