Scenarios First check whether the ECS and RDS DB instance are in the same security group. If they are in the same security group, they can communicate with each other by default. No security group rule needs to be configured.
When your applications are deployed on an ECS that is in the same region and VPC as the RDS for MariaDB instance, you are advised to use a floating IP address to connect to the instance through the ECS.
NOTE: If you are accessing the DB instance through an ECS, instance_ip is the floating IP address of the instance. You can obtain this IP address on the Connectivity & Security page.
