Amazon EC2 Auto Scaling helps you maintain application availability and allows you to automatically add or remove EC2 instances according to conditions you define. This allows you to scale up or down as needed to handle changes in demand without having to manually manage the number of instances. It also enables you to automatically adjust the number of instances based on metrics. This ensures that your application is always available and running optimally, even when demand fluctuates.

• Improve Fault Tolerance

Automatically scales an application’s computing resources in response to changes in traffic or load for increased redundancy and scalability

• Increase Application Availability

Users can ensure that their application is always available, even during peak times, by scaling the number of EC2 instances up or down as needed

• Lower Costs

Allows you to ensure that your application always has the right amount of compute capacity to meet the demands of your users while keeping costs in check
