Deployment

• Making changes in the API Gateway does not mean they're effective

  ⇒ need to make a "deployment"

• Changes are deployed to "Stages", can use the naming you like for stages (dev, test, prod)

• Each stage has its own configuration parameters

• Stage can be rolled back as a history of deployments is kept

• Stage variables are like environment variables for API Gateway

Stage Variables & Lambda Aliases
