Does serverless call aws cli externally from local environment?

Hello, we are using serverless.yml. In our pip install requirements.txt we are installing aws cli 1.*. Is the runtime where aws cli is being used?

  name: aws
  runtime: python3.7

Hello @dman777 - I don’t really understand the question, could you rephrase it? Is there a reason why you’re installing aws-cli via pip?
