If your database is stored on Amazon RDS there are a few extra considerations you'll have to take in connecting it to Chartio. First, you cannot use the Chartio connection client—you'll need to use the direct connction method instead. Second, Amazon has some unique security group settings that mean you'll need to explicitly enable access to a Chartio server. The following documentation will walk you through those steps.
In order for Chartio to connect to your database, your RDS security group needs to be modified in order to white-label Chartio's inbound IP address. To view your security groups, access your RDS Management Console.

Navigate to DB Security Groups from the left sidebar and select one of your security groups. A form for a CIDR will be presented. Paste the Chartio CIDR: 173.203.96.249/32 into the form and click Add to add Chartio to your security group.
Note to VPC Users: If you're using the Amazon Virtual Private Cloud (VPC) you'll need to set up an elastic IP for your RDS instance to make it accessable to Chartio's servers outside your VPC.
Now you can add a data source from your Chartio settings. Choose the Direct Connection option and follow the on-screen instructions for connecting to your database type. The Direct Connection method is needed as RDS does not allow terminal access to their database instances, so the Connection Client method cannot be used.
