The short version

  • CloudAMQP is a managed RabbitMQ hosting service billed per second.
  • Azure Functions is free; CloudAMQP starts at $19/mo.
  • Where Azure Functions falls short: the newer Flex Consumption plan's free grant is smaller still, at 250,000 executions and 100,000 GB-seconds per month.
  • Where CloudAMQP falls short: free tier messaging limits are low: 1-2M messages/month.
  • Prices and features on this page were last checked on 13 November 2026.

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

CloudAMQP

  • Free tier messaging limits are low: 1-2M messages/month
  • Free tier connection limits are restrictive: 20-40
  • Multi-tenant plans have queue limits (200-2,000 max)
  • Dedicated plans expensive at scale: up to $14,995-$17,495/month
  • Extra disk space add-on at $0.35/month per GB may add significant cost
