Does AWS support Autoscaling for RDS Instance

Question

One of my RDS instance take high cpu some times due to heavy load. That time we manually need to upgrade instance. So I think to use auto scaling feature of RDS to automatically increase instances, but not getting any details about it.

Please some one confirm that If Autoscaling supports for RDS instances or not..

Thanks in advance.

Answer 1

The previous answers are now out of date. The newer AWS RDS Aurora does support autoscaling. Aurora Auto Scaling is available for both Aurora MySQL and Aurora PostgreSQL.

Answer 2

No, it does not.

The scaling you're describing is vertical scaling, which is upgrading the class or type of an instance. Autoscaling, in general, is for horizontal scaling: adding more instances. RDS supports neither horizontal nor vertical autoscaling, but it does support manual horizontal scaling (by adding read replicas) and manual vertical scaling (by upgrading/downgrading an existing instance).
