title: How to change a RDS availability zone to a different one within the same region on AWS?
body: <p>I currently have a EC2 instance working with an MySQL RDS database. They are both in the same region, but in different availability zones. Currently my application is experiencing a bit of lag, and it is my intuition that it is due to this.</p>
  <p>How can I change the AZ of my RDS database to speed up my application?</p>
  <p>Locally I am running the same application and it is significantly faster.</p>
