Now, both “Stop” actions can optionally suspend an Auto Scaling group’s processes so that the stopped EC2 instances are not terminated and replaced. However, that will cause the EC2 instances to terminate instead of stop. You could use our “Update Auto Scaling Groups” action to adjust the desired number of instances. If your EC2 instances are controlled by Auto Scaling Groups, then stopping those instances causes Auto Scaling to terminate and recreate them. Now you can schedule that stop and restart to happen at a convenient time. The instances need to be stopped and restarted before a deadline so that they can move hardware. We’ve all received those emails from AWS regarding EC2 instances that are scheduled for retirement. Schedule Your Retiring EC2 Instances to Stop and Restart At a Convenient Time Now, using a single “Stop Multiple EC2 Instances” action, you can stop your development EC2 instances on Friday evening, and restart them on Monday morning.

We have enhanced our “Stop EC2 Instance” and “Stop Multiple EC2 Instances” actions to better fit some workflows. Using the “Start” actions may work, but they may not be the exact fit for your workflow. However, what if your desired workflow were to stop the instance at key times.

Until now, if you wanted to both start and stop your EC2 instances with a single action, you would use one of the “Start” actions. The actions you choose to use depend on your desired workflow.
