Amazon VPC and Amazon RDS
Amazon Virtual Private Cloud (Amazon VPC) makes it possible for you to launch AWS resources, such as Amazon RDS DB instances, into a virtual private cloud (VPC).
When you use a VPC, you have control over your virtual networking environment. You can choose your own IP address range, create subnets, and configure routing and access control lists. There is no additional cost to run your DB instance in a VPC.
Accounts have a default VPC. All new DB instances are created in the default VPC unless you specify otherwise.
