Benefits

Fast scaling:

As a simple and straightforward interface, AWS ASG allows you to establish utilization values for numerous resources. Without switching between consoles, you can instantly observe the overall utilization of all your scaled resources. For example, if your application relies on AWS EC2 and DynamoDB, the user can use auto-scaling to handle resource allocation across all EC2 instances.

Pay only for what you use:

While using services, AWS auto-scaling can help you optimize your utilization and cost savings since you only spend on the tools you need. AWS ASG seamlessly eliminates any available surplus resources whenever demand drops which prevents you from overpaying.
