How Do My Applications Access an RDS DB Instance in a VPC?

Ensure that the ECS where in which your applications are located is in the same VPC and subnet as the RDS DB instance. If the ECS and the RDS DB instance are in different subnets or VPCs, modify the VPC route table and network access control list (ACL) to ensure that the ECS can access the RDS DB instance.
