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

Bitdefender Total Security

  • VPN limited to 200MB per day, insufficient for streaming video or extended browsing sessions
  • Limited features on Apple devices with iOS version lacking scheduled scans, firewall, file shredder, and other tools
  • Failed to detect 10% of virus samples during in-house testing, falling short of perfect detection rates
  • Auto-renewal billing issues with complaints about unauthorized recurring charges and difficulties with refunds
  • Device optimization tools less extensive than competitors, lacking game booster, driver updater, startup manager, and battery usage manager
