This document discusses Amazon EC2 Auto Scaling and AWS Auto Scaling. It provides an overview of EC2 Auto Scaling for scaling EC2 instances, Application Auto Scaling for services like ECS, and AWS Auto Scaling which unifies scaling across different AWS resources. It also covers various scaling options like target tracking, step scaling policies, and scheduled scaling. Best practices for setting up auto scaling groups and examples of using different scaling configurations are presented.
