Autoscaling Groups (ASG)

Create Autoscaling groups to scale EC2 instances to your workload

Configure Autoscaling Groups (ASG) to ensure the application load is scaled based on the number of EC2 instances configured. Autoscaling detects unhealthy instances and launches new EC2 instances. ASG is also cost-effective as EC2 Instances are dynamically created per the application requirement within minimum and maximum count limits.

For cluster autoscaling, enable the Cluster Autoscaler option in your Infrastructure before creating an ASG.
