Amazon EC2 Auto Scaling
Amazon EC2 Auto Scaling is an AWS service that automatically launches or terminates Amazon EC2 instances based on user-defined rules, schedules, and health checks. It ensures the right number of instances are running so applications remain available and can handle changing workloads.
It enables creating Auto Scaling groups that define the minimum, maximum, and desired number of instances. The service automatically adds instances during demand spikes or removes them when demand decreases, helping to reduce costs.
Amazon EC2 Auto Scaling also provides features such as health checks to automatically replace unhealthy machines and schedules to plan instance changes at specific times. It integrates with Amazon CloudWatch to react to metrics and alarms in real time, enabling dynamic, flexible, and reliable application scaling in AWS.
