AWS - Pause autoscaling after failed retries

I have setup some Autoscaling LifeCycle hooks, where some of my other applications plug on those hooks and perform various actions (deploy app update, etc.)

However, I know that at some point my apps will fail and lifecycle hooks will never be able to complete. And therefore, AWS autoscaling will keep spawning/terminating new instances and possibly eat my money and generate noise for nothing.

Is there some protections that - are already in place by AWS ? - I can add to suspend autoscaling operations if I detect too many fails without ay success ?

AutoScaling will keep trying to launch new EC2 Instances for 24 hours.

Suspending and Resuming Scaling Processes

You can suspend and then resume one or more of the scaling processes for your Auto Scaling group. This can be useful when you want to investigate a configuration problem or other issue with your web application and then make changes to your application, without triggering the scaling processes.

Amazon EC2 Auto Scaling can suspend processes for Auto Scaling groups that repeatedly fail to launch instances. This is known as an administrative suspension, and most commonly applies to Auto Scaling groups that have been trying to launch instances for over 24 hours but have not succeeded in launching any instances. You can resume processes suspended for administrative reasons.

As far as I know, you cannot change this parameter.
