Detach server groups from a scaling group. To seamlessly adjust the number of instances in response to changes in your business workload or to maintain the uninterrupted accessibility of your application, you can call the DetachServerGroups operation. By detaching Application Load Balancer (ALB) or Network Load Balancer (NLB) server groups from your scaling group, this operation enables Auto Scaling to automatically tailor your computing capacity to your business needs. Furthermore, it optimizes traffic routing by dynamically allocating incoming requests based on current workload patterns, which significantly improves the stability and performance of your application.
