Auto Scaling Instances
You can manage auto scaled instances by clicking on the "Instances" button.
If you need to terminate an auto scaled instance, click on the button. You can also change the state of the instance, from healthy to unhealthy, by clicking on the button. Flagging an instance as "unhealthy" will trigger an auto scaling action if the processes are still being enforced.
If your auto scaling processes are enabled, stopping or terminating instances will cause auto scaling to spawn new instances, to maintain the minimum capacity you specified. If you do not want this to happen, you need to suspend the auto scaling processes first. To learn more about suspending scaling, go HERE.
