You have decided to leverage EC2 Auto Scaling to scale your application efficiently. To start, you create an EC2 Auto Scaling group without any Auto Scaling policies.

  1. In Cloud9 IDE terminal, check you’re at this directory ec2-spot-workshops/workshops/efficient-and-resilient-ec2-auto-scaling.
  2. You create an Auto Scaling group using asg.json configuration file, open the file to review the configuration.
    cat ./asg.json
  3. Create the auto scaling group using below command. This command does not return any output if it is successful.
    aws autoscaling create-auto-scaling-group --cli-input-json file://asg.json
  4. Then run this command to enable CloudWatch metrics collection for the Auto Scaling group, which will help you in monitoring the capacity in the group.
    aws autoscaling enable-metrics-collection \
     --auto-scaling-group-name ec2-workshop-asg \
     --granularity "1Minute"
  5. Browse to the Auto Scaling console and check out your newly created auto scaling group. At this step of the workshop, the auto scaling group will have no instances running, as the desired number of instances is set to 0.
