Do you mean "Amazon Linux" rather than "AMI instance"? Difficult to say based on the little information you've provided, Amazon Linux connects to RDS fine when properly configured. You can't ping RDS to test connectivity, but you can telnet or similar to port 3306 to see what happens. What happens when you try that? Can the instance connect to each other? Is iptables running and blocking connections? Please edit your question to show the work you've done / do for diagnostics.

Do you mean "Amazon Linux" rather than "AMI instance"? Difficult to say based on the little information you've provided, Amazon Linux connects to RDS fine when properly configured. You can't ping RDS to test connectivity, but you can telnet or similar to port 3306 to see what happens. What happens when you try that? Can the instance connect to each other? Is iptables running and blocking connections? Please edit your question to show the work you've done / do for diagnostics.
