问题
I have just created RDS Instance in N.Virginia & trying to connect that database using Navicat.
But I'm unable to connect it.
After searching over internet I came to know that we need to configure Security Groups. But in my case there is a notification :
Your account does not support the EC2-Classic Platform in this region. DB Security Groups are only needed when the EC2-Classic Platform is supported. Instead, use VPC Security Groups to control access to your DB Instances. Go to the EC2 Console to view and manage your VPC Security Groups. For more information, see AWS Documentation on Supported Platforms and Using RDS in VPC.
Please help me out to resolve the issue. And also N.Virginia is what the AWS assigned automatically. It is good to opt for N.Viginia in Free-tier.

I would probably not advised to get a direct link on your RDS Database from your local system; I would probably recommend to be able to only log in form ec2 instance, but lets look
When you create your Database in RDS (will be Oracle, mysql ...) you defined how/who will access it.
- Make your instance Publicly Accessible
Select Yes if you want EC2 instances and devices outside of the VPC hosting the DB instance to connect to the DB instance. If you select No, Amazon RDS will not assign a public IP address to the DB instance, and no EC2 instance or devices outside of the VPC will be able to connect. If you select Yes, you must also select one or more VPC security groups that specify which EC2 instances and devices can connect to the DB instance.
If you say yes you will be able to connect to your database from your local laptop. If you say no well only ec2 instance launched from within the same VPC will be able to access it.
- Define your VPC security groups
If you select an existing VPC, you probably have some defined security groups. In case you dont have VPC or no existing security groups. The Security groups can be viewed as acting like a firewall, you defined which port are opened and who can access.
If you leave Create new Security Group the DB will launch and a new Security Group will have been created. You can review from the AWS Console (make sure to select the same region where you created your DB) or directly https://console.aws.amazon.com/vpc/home?region=us-east-1#securityGroups: (replace the region in case you use something else). The new Security Group created will be named rds-launch-wizard
Edit the Security Group and review the inbound rules, by default AWS will have created a new rule to open the port (depending the DB) to your IP, you can change that to open to more IP or restrict further.
Security Rules are predefined for the RDS supported database (Oracle, MS SQL and MySQL/Aurora) so just select the right item from the list when you add a new inbound rule
When the DB instance has launched you can review the endpoint
and so you are able to connect from your local laptop

If you prefer to connect using Navicat, you should be able to set the settings to establish the same connection.
