Virtual Private Clouds (VPCs) and Amazon RDS

There are two Amazon Elastic Compute Cloud (EC2) platforms that host Amazon RDS DB instances, EC2-VPC and EC2-Classic. Amazon Virtual Private Cloud (Amazon VPC) lets you launch AWS resources, such as Amazon Relational Database Service (Amazon RDS) DB instances, into a virtual private cloud (VPC).

Accounts that support only the EC2-VPC platform have a default VPC. All new DB instances are created in the default VPC unless you specify otherwise. If you are a new Amazon RDS customer, if you have never created a DB instance before, or if you are creating a DB instance in a region you have not used before, you are most likely on the EC2-VPC platform and have a default VPC.

Some legacy DB instances on the EC2-Classic platform are not in a VPC. The legacy EC2-Classic platform does not have a default VPC, but as is true for either platform, you can create your own VPC and specify that a DB instance be located in that VPC.

This documentation only discusses VPC functionality relevant to Amazon RDS DB instances. For more information about Amazon VPC, see Amazon VPC Getting Started Guide and Amazon VPC User Guide.
