I'm planning to run a PHP/MySQL application using Amazon Elastic Beanstalk. In the settings I can define when it should launch new instances automatically (Auto-Scaling).
However, as I understand this, this only creates new EC2-Instances and does not touch the RDS-Data-Layer (which I also configured in the settings).
Is there any way to auto-scale this RDS, with automated Read-Replicas or database size upgrade, or do I have to do this manually in some way?
