Determining Whether You Are Using the EC2-VPC or EC2-Classic Platform

Your AWS account and the region you select determines which of the two RDS platforms your DB instance is created on: EC2-Classic or EC2-VPC. The type of platform determines if you have a default VPC, and which type of security group you use to provide access to your DB instance. The legacy EC2-Classic platform is the original platform used by Amazon RDS; if you are on this platform and want to use a VPC, you must create the VPC using the Amazon VPC console or Amazon VPC API. Accounts that only support the EC2-VPC platform have a default VPC where all DB instance are created, and you must use either an EC2 or VPC security group to provide access to the DB instance.

Note

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, in almost all cases you are on the EC2-VPC platform and have a default VPC.

You can tell which platform your AWS account in a given region is using by looking at the dashboard on the RDS console or EC2 console. 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 might be redirected to the first-run console page and will not see the home page following.

If Supported Platforms indicates VPC, as shown following, your AWS account in the current region uses the EC2-VPC platform, and uses a default VPC. The name of the default VPC is shown below the supported platform. To provide access to a DB instance created on the EC2-VPC platform, you must create a VPC security group. For information about creating a VPC security group, see Tutorial: Create an Amazon VPC for Use with an Amazon RDS DB Instance.


				EC2-VPC platform

If Supported Platforms indicates EC2,VPC, as shown following, your AWS account in the current region uses the EC2-Classic platform, and you do not have a default VPC. To provide access to a DB instance created on the EC2-Classic platform, you must create a DB security group. For information about creating a DB security group, see Creating a DB Security Group.


				EC2-Classic platform

Note

  • You can create a VPC on the EC2-Classic platform, but one is not created for you by default as it is on accounts that support the EC2-VPC platform.

  • If you are interested in moving an existing DB instance into a VPC, you can use the AWS Management Console to do it easily. For more information. see Moving a DB Instance Not in a VPC into a VPC.
