Detailed explanation-1: -Amazon EC2 Auto Scaling metrics that collect information about Auto Scaling groups are in the AWS/AutoScaling namespace. Amazon EC2 instance metrics that collect CPU and other usage data from Auto Scaling instances are in the AWS/EC2 namespace.
Detailed explanation-2: -With step scaling, the policy can continue to respond to additional alarms even in the middle of the scaling event. In this example, the Auto Scaling group maintains its size when the CPU utilization is between 40% and 60%.
Detailed explanation-3: -Step scaling policies and simple scaling policies are two of the dynamic scaling options available for you to use. Both require you to create CloudWatch alarms for the scaling policies. Both require you to specify the high and low thresholds for the alarms.
Detailed explanation-4: -In Simple Autoscaling Policy, you define the threshold value and upper bound. The alarm monitors the metric values. When the metric value breaches the threshold, the scaling policy acts. The instances are added or removed as per the policy.
