How To Create Autoscaling Group In AWS Using Terraform ?
An auto-scaling group is a service that is provided in EC2 and is primarily used for an automatic increase or decrease in a number of EC2 instances based on the application’s user traffic. For example, if your application is experiencing high traffic, the auto-scaling group can launch extra instances to handle the increased load, and if the traffic coming towards to application is low, the auto-scaling group can shut down or terminate unnecessary instances for cost-saving purposes. The auto-scaling group can be created based on scaling policies, These policies can be defined for scaling in and out in response to various metrics, such as CPU utilization, network traffic, or custom metrics.
