AWS Auto Scaling is a feature that automatically adjusts the number of Amazon EC2 instances based upon the current demand. This ensures applications have enough resources to maintain performance and optimize costs. Auto Scaling is operated by two components: The Auto Scaling Group and the Scaling Policies.

Auto Scaling groups are logical groups of EC2 instances with the same configuration that can be managed together. The group specifies the maximum and minimum number of instances at any one time. This provides a safety net against both under-provisioning and over-provisioning which can lead to excessive expenses.

Scaling policies determine how and when the Auto Scaling group will scale up or down. These policies may be based upon various metrics such as CPU usage, network traffic or custom Cloud Watch metrics. Scaling policies can be configured, for example, to increase instances when CPU utilization exceeds a threshold or reduce instances when usage falls below a specified level.

Auto Scaling integrates Elastic Load Balancing to distribute traffic equally across all instances within the Auto Scaling Group. This helps to ensure that no instance is overloaded with requests. AWS Training in Mumbai

AWS Auto Scaling automates the scaling process to help businesses manage their resources efficiently. This ensures that they pay only for the resources they require while maintaining performance and availability. This dynamic resource management can be especially beneficial for applications that have variable workloads such as those with seasonal traffic spikes and unpredictable user demand.
