The short version

  • Only Apache HTTP Server has a free tier, so it costs nothing to try first.
  • Each has a real cost: Apache HTTP Server process-based or thread-based architecture consumes more memory per connection than nginx's event-driven model; 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

Where each one falls short

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

Apache HTTP Server

  • Process-based or thread-based architecture consumes more memory per connection than nginx's event-driven model
  • Static file serving performance lags behind nginx, particularly under high concurrency
  • Module system flexibility can add overhead compared to nginx's streamlined single-purpose design
  • Configuration complexity for advanced features like reverse proxying is higher than nginx
  • Performance monitoring in hybrid and cloud environments requires additional tools beyond built-in diagnostics

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
