title: AWS cross region lambda database access
body: <p>Recently <a href="https://forums.aws.amazon.com/message.jspa?messageID=754988" rel="nofollow noreferrer">some service in us-west-1 seems not working</a>, so I'm trying to create a lambda that can access cross-region RDS (from <code>us-east-1</code> to <code>us-west-1</code>), but I cannot find any solution or sample with these keywords. Does that means cross-region database is unavailable?</p>
  
  <p>As I know, use lambda reach to database in VPC may cause out of IP issues, so is there any best practice for this?</p>
  
  <p>Thanks</p>
