Experimenting with AWS FIS on EC2 instances with a CPU stress action
In this section of the chapter, we will create an FIS experiment template that applies CPU stress to an EC2 instance using Amazon Systems Manager Agent. We will validate the fact that once the chaos experiment starts giving CPU stress to an EC2 instance and CPU utilization of the server increases by more than 50%, then ASG should automatically increase a new instance and take over the load.
Perform the following steps to implement the experiment using AWS FIS:
- Since the AWS FIS CPU stress action uses an SSM agent on an EC2 instance, make sure that the SSM agent is installed and that the
AmazonSSMRoleForInstanceQuickSetupIAM role is attached to both servers running in ASG. Amazon Linux 2 AMI comes with an SSM agent installed and in a running state. In Step 2 | IV of the previous section, Experimenting with AWS FIS on multiple EC2 instances with a terminate action, we also applied the IAM role to the launch...
