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; TypeScript requires build/compilation step; adds complexity to development workflow
  • They diverge on capability: Lambda (AWS Serverless) covers Function-as-a-Service, TypeScript covers Static typing.

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

TypeScript

  • Requires build/compilation step; adds complexity to development workflow
  • Performance slower than compiled languages like Rust or Go when running on same hardware
  • Type safety only at compile-time; runtime errors still possible if types are misused
  • JavaScript ecosystem requires understanding both TypeScript and JavaScript
