AWS Lambdas

  • Lambdas are like a function floating around in space
  • AWS could run your code from scratch every execution
  • Technically your function gets deployed on a server (that you can't control)
  • A function may get re-used if AWS wants to reuse it
  • No strong guarantee of when this happens though
  • There is a noticeable performance hit when AWS does not reuse your code
  • This is a "cold start"
