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

CrowdStrike Falcon

  • Falcon Go device limit: capped at 100 devices maximum, forcing mid-market/enterprise customers to upgrade despite lower cost
  • EDR locked behind Enterprise tier: endpoint detection and response available only at $19.99/device/month tier; not available in Pro
  • Managed service pricing opaque: Falcon Complete Next-Gen MDR requires contacting sales; no pricing range for 24/7 MDR services published
  • Annual discount modest: 17-24% savings on annual vs. monthly create minimal incentive to prepay
