Hey AgitatedDove14 , basically https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-instance-protection.html would allow blocking the machine from being scaled-in when there is a scale-in event in the ASG.
The ASG is responsible for spinning up on demand in the ClearML queue, but spinning down is less trivial – we cannot just spin down is the queue is empty (some machine can still be running something important!)
