title: How to connect to a RDS instance in a different AWS region
body: <p>I have an EC2 instance in one region, N.California. I have an RDS instance in EU/Ireland. I am not able to connect to the RDS instance from the EC2 instance, the connection times out. This <a href="http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_VPC.Scenarios.html#USER_VPC.Scenario3" rel="nofollow">tutorial by aws</a> says that I would need to use the Public IP of the RDS instance in order to connect to it. But this public IP is not available on the AWS console, I'm not even sure if we're supposed to be using any other than RDS endpoints. We're also disallowed from adding a security group from one region to the security group of another.</p>
  
  <p>I am really unsure about how to proceed.</p>
