• A PHP page
• One item is added to a DynamoDB table
• The Cloudwatch Agent is installed and configured. These configuration doesn't make any sense in a real scenario but it's useful for training purposes. An Application Load Balancer and a DynamoDB table are configured too. Finally, an instance profile is created to allow the autoscaling group instance to get access to Dynamo and CW.
