Answer / Maneesh
Auto Scaling in Amazon Web Services (AWS) allows automatic adjustment of the number of EC2 instances in a group, based on certain conditions such as CPU utilization or demand. Here's an example: A web application is deployed on an Auto Scaling Group with minimum 3 instances and maximum 5 instances. If the CPU usage of these instances exceeds 70%, Auto Scaling will automatically launch new instances up to the maximum limit (5) to handle the increased load. Similarly, if the demand decreases and CPU usage falls below a certain threshold, it will terminate idle instances down to the minimum limit (3).
