Scaling: Add an Auto Scaling Group

Amazon Auto Scaling groups (ASG) is a cloud service that allows for the automatic scaling up and down of cloud resources in response to changing demand.

An ASG consists of a collection of EC2 instances that are logically grouped together.

In this Cloud Lab, you’ll create EC2 instances within an ASG and test the behavior of the ASG in case an instance fails. Afterward, you’ll clean up all the resources created in this Cloud Lab.

The following is the high-level architecture diagram of the infrastructure that you’ll create in this Cloud Lab to add an Auto Scaling group to the EC2 instance:

Lab tasks

• Create an S3 Bucket to Store CodeBuild Artifacts
• Create a Stack on CloudFormation
• Create an ASG
• Attach the Instances Created by CloudFormation to the ASG
• Test the ASG
• Clean Up
