Step and simple scaling policies for Amazon EC2 Auto Scaling

To Nha Notes | May 19, 2021, 11:03 a.m.

We strongly recommend that you use a target tracking scaling policy to scale on a metric like average CPU utilization or the RequestCountPerTarget metric from the Application Load Balancer. Metrics that decrease when capacity increases and increase when capacity decreases can be used to proportionally scale out or in the number of instances using target tracking. This helps ensure that Amazon EC2 Auto Scaling follows the demand curve for your applications closely.

You still have the option to use step scaling as an additional policy for a more advanced configuration.
