 ## Autoscaling test
 
 To test how your application will perform under a peak of traffic, a stress test configuration file is provided.
 
 For this stress test [Artillery](https://artillery.io/) is being used. Please be sure to install it following [these](https://artillery.io/docs/guides/getting-started/installing-artillery.html) steps.
 
-Once installed please change the ALB DNS to the desired layer to test (front-/backend) in the **target** attribute, which you can copy from the generated Terraform output, or you can also search it in the AWS Management Console.
