What is target value in AWS Auto Scaling?
With target tracking, you select a load metric for your application, such as “Average CPU Utilization” or the new “Request Count Per Target” metric from Application Load Balancer, set the target value, and Auto Scaling adjusts the number of EC2 instances in your Auto Scaling group as needed to maintain that target..
Does ec2 auto scale?

What are the types of scaling policies available within Auto Scaling groups?
Scaling policy types Step scaling—Increase or decrease the current capacity of the group based on a set of scaling adjustments, known as step adjustments, that vary based on the size of the alarm breach. Simple scaling—Increase or decrease the current capacity of the group based on a single scaling adjustment.
What is the difference between auto scaling and load balancing?
Load balancing evenly distributes load to application instances in all availability zones in a region while auto scaling makes sure instances scale up or down depending on the load.
What are the two main components of AWS Auto Scaling?

What is scale in and scale out in AWS?
Scaling out is when you add more instances to your Auto Scaling Group and scaling in is when you reduce the number of instances in your Auto Scaling Group. When you scale out, you distribute your load and risk which in turn provides a more resilient solution, here is an example: Let’s say you have an ASG with 4x m4.
What are Auto Scaling groups?
An Auto Scaling group contains a collection of Amazon EC2 instances that are treated as a logical grouping for the purposes of automatic scaling and management. An Auto Scaling group also enables you to use Amazon EC2 Auto Scaling features such as health check replacements and scaling policies.
