Compute
Overview
We have an Auto Scaling Group which can scale up or down the number of instance in public Subnet.
The EC2 instance in the Auto Scaling Group will automatically run a script to install an Apache Web Server.
We also create Target Tracking Policy with policy type is Target tracking scaling, Metric type is Average CPU Utilization, and Target value is 50.
-> The policy is set to target tracking scaling with a target value of 50% CPU utilization.
It ensures that the Auto Scaling Group maintains the desired CPU utilization by scaling the number of instances up or down accordingly.
