What is Auto Scaling

Last Updated: Apr 10, 2018

Auto Scaling enables you to dynamically scale your computing capacity up or down to meet the workload of your ECS instances according to scaling policies you specify, and reduces the need of manual provision. It monitors your resources, automatically adds or removes capacity in real time as demands change, so as to guarantee availability and save costs.
