1. Use the launch configuration that created in Creating launch configuration.
  2. Optional: Attach the ELB to the auto-scale group that you created in step 1.
  3. Configure the following rules for the auto scale group:
    1. To configure the Increase Group Size rule, add one instance when the Average CPU utilization is greater than 90% for at least 2 consecutive periods of 5-minutes.
    2. To configure the Decrease Group Size rule, remove one instance when the Average CPU utilization is less than 10% for at least two consecutive periods of 5-minutes.

Optionally, you can uninstall the API Security Enforcer (ASE) service installed in Creating an AMI for ASE by running the uninstall_service.sh command, which results in an output similar to the following:

/opt/pingidentity/ase/bin$sudo ./uninstall_service.sh
This script will uninstall ASE service
