title: How to scale horizontally Amazon RDS instance?
body: <p>How to scale horizontally amazon RDS instance? EC2 and load balancer+autoscaling is extremly easy to implement, but if I want scaling amazon RDS?
  I can ugrade my RDS instance with more powerfull instance or I can create a read replica and I can direct SELECT queries to it. But in this mode I don't scale anything if I have a read-oriented web application. So, can I create RDS read replica with autoscaling and balance them with load balancer?</p>
