title: Why do I need to enable instance scale-in protection in my Auto Scaling Group when enabling a capacity provider within a cluster?
body: <p>I am making an AWS ECS cluster using EC2 and trying to use capacity providers. I don't really understand why do I need to enable instance scale-in protection inside my AWS Auto Scaling group.</p>
  <p>Isn't the point of Auto Scaling the termination of needless EC2 instances?</p>
