Stressing EC2 to see Auto-scale in Action

Login to both the instance created by auto-scaling group and run below commands on both
```
sudo su
yum install stress -y
stress -c 70
```
Above commands will basically put a load 70% on both of your instance which should ideally trigger your Auto-Scaling policies and add one more EC2 instance to your group
As auto-scaling depends on cloudwatch to provide utilization data and we are using basic monitoring as of now, it will take 5 min of 70% CPU load to add more instance
Now delete your auto-scaling group then launch configuration, this will also delete the EC2s
Also delete the AMI which was created in previous lab
