If you are an Alibaba Cloud architect, which 2 Auto Scaling and OOS features would you recommend, in order to automatically add and remove instances from the Redis whitelist?

A user builds an ECS + SLB -t RDS business application architecture on the cloud, and uses Auto Scaling to flexibly scale-in and scale out ECS instances. For business reasons, you need to use Apsara DB for Redis as a cache for hot data storage to ensure high-speed data access for applications. However, the Auto Scaling Scaling Group cannot be associated with a Redis instance directly, you need to manually configure ECS instances to be added to or removed from the Redis whitelist, which is time-consuming, laborious and inefficient.
