In Auto Scaling, a scaling group refers to the collection of ECS instances deployed with the same applications, where these ECS instances can be charged by monthly subscription or Pay-As-You-Go. For scenarios with abrupt service traffic change, Pay-As-You-Go ECS instances can meet service requirements while minimizing cost. For monthly subscription ECS instances, you can manually add the idle instances to the scaling group to take full advantage of idle resources.

You are designing a solution for a startup company, the proposed solution is like this You suggest they use ECS instances to process requests from mobile App clients, and use SLB to distribute data traffic and ensure the load across each backend ECS instance is balanced.
Moreover to deal with volatile fluctuations in business volume (page views are much higher on the weekends), you also suggest they use Auto Scaling to dynamically increase or reduce computing resources.
The company is satisfied with the solution you proposed. However, they have one concern that when removing an idle instance from the scaling group: if Auto Scaling shuts the instance down directly, the service running on that instance will be abruptly terminated, resulting in poor user experience.
In order to eliminate your customer's concern, which of the following solutions should you recommend them?
