Is Amazon-Web-Services – AWS supports automatic extension of RDS Insance

By Silicon Valley

Due to the heavy load, one of my RDS instances sometimes consumes high CPU. At that time, we need to upgrade the instance manually. So I think we use the automatic scaling function of RDS to automatically increase the instance, but Did not get any details about it.

Can someone please confirm if Autoscaling supports RDS instances

Thanks in advance.

No, it’s not.

The zoom you describe is vertical zoom, that is, the class or type of the upgraded instance. Normally, automatic Scaling is used to scale horizontally: add more instances. RDS supports neither horizontal nor vertical automatic scaling, but it supports manual horizontal scaling (by adding read-only replicas) and manual vertical scaling (by upgrading/downgrading existing instances).
