The short version

  • Each has a real cost: Lambda (AWS Serverless) billed on two axes at once, $0.20 per million requests plus $0.0000166667 per GB-second of duration, so memory settings change the bill as much as traffic does; Node.js slower cold-start time in serverless environments compared to Bun which wakes up in under 5ms
  • They diverge on capability: Lambda (AWS Serverless) covers Function-as-a-Service, Node.js covers V8 JavaScript engine.

Where each one falls short

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

Lambda (AWS Serverless)

  • Billed on two axes at once, $0.20 per million requests plus $0.0000166667 per GB-second of duration, so memory settings change the bill as much as traffic does
  • Provisioned concurrency, used to avoid cold starts, is charged separately at $0.0000041667 per GB-second whether or not the function runs
  • Ephemeral storage beyond the included 512 MB is metered
  • Lambda@Edge costs $0.60 per million requests, three times the standard request rate
  • VPC use and cross-region data transfer carry EC2 charges on top

Node.js

  • Slower cold-start time in serverless environments compared to Bun which wakes up in under 5ms
  • Requires separate setup for TypeScript support unlike Deno which treats TypeScript as native
  • Larger memory footprint on startup compared to lightweight alternatives like Deno
