  • Uses the config.json file for AWS credentials and region.

• executePolicy.js: Executes a scaling policy for the Auto Scaling group.

  • Takes the policy name as a command-line argument.
  • Executes the specified policy with the option to honor cooldown.
  • Uses the config.json file for AWS credentials and region.

• stopInstance.js: Stops an EC2 instance and creates an AMI from it.

  • Takes the instance ID as a command-line argument.
  • Stops the instance and waits for it to stop.
  • Creates an AMI with specified block device mappings, description, and name.
  • Uses the config.json file for AWS credentials and region.

• demo.js: Creates the complete infrastructure for the application.

  • Creates a load balancer, target group, listener, Auto Scaling launch configuration, Auto Scaling group, scaling policies, and CloudWatch alarms.
