Benefits Of Using Autoscaling Group
Dynamic Resource Management: Auto-scaling groups have a capability of dynamically adding or removing EC2 instances based on the demand for the application. This means that users don’t have to manually change the number of servers or resources, because the Auto Scaling group handles it dynamically.
Available and Reliable: Auto-scaling groups help ensure the application is always run and available to users, even if one or more instances fail. If any instance crashes down, the Auto Scaling group will immediately launch a new instance to continue the application without causing any failure.
Load Balancers Facility: Auto Scaling groups have a facility of load balancers, they forward incoming traffic to instances evenly. so that the application remains available This integration helps improve the performance of the application, especially during times of high traffic.
Cost Saver: When application doesn’t have much traffic or demand, the Auto Scaling group can automatically reduce the number of servers, so users don’t pay for resources they don’t need. This can save money on cloud computing costs.

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.
