Currently autoscaling is predefined with conditions like
scale up:
The Average CPU Utilization has exceeded 75% for the past hour.
The Memory Utilization has exceeded 75% for the past hour.
scale down:
The average CPU Utilization and Memory Utilization over the past 24 hours is below 50%.
The cluster hasn't been scaled down (manually or automatically) in the past 24 hours.
Following changes will save more resources and money:
-This 24 hours time for scale down should be made flexible/adjustable to suit customers requirement.
-One hour time to scale up should be adjustable to scale up faster. This may need for some critical application.
First one will save more valuable resource and money while db will be running in optimized condition
Second one will reduce critical application failure by adjusting scale up time
