Supported Platforms

Amazon EC2 supports the following platforms. Your AWS account is capable of launching instances either into both platforms or only into EC2-VPC, on a region by region basis.

PlatformIntroduced InDescription

EC2-Classic

The original release of Amazon EC2

Your instances run in a single, flat network that you share with other customers.

EC2-VPC

The original release of Amazon VPC

Your instances run in a virtual private cloud (VPC) that's logically isolated to your AWS account.

For more information about the availability of either platform in your account, see Availability in the Amazon VPC User Guide. For more information about the differences between EC2-Classic and EC2-VPC, see Differences Between EC2-Classic and EC2-VPC.

Supported Platforms in the Amazon EC2 Console

The Amazon EC2 console indicates which platforms you can launch instances into for the selected region, and whether you have a default VPC in that region.

Verify that the region you'll use is selected in the navigation bar. On the Amazon EC2 console dashboard, look for Supported Platforms under Account Attributes. If there are two values, EC2 and VPC, you can launch instances into either platform. If there is one value, VPC, you can launch instances only into EC2-VPC.

If you can launch instances only into EC2-VPC, we create a default VPC for you. Then, when you launch an instance, we launch it into your default VPC, unless you create a nondefault VPC and specify it when you launch the instance.

EC2-VPC

The dashboard displays the following under Account Attributes to indicate that the account supports only the EC2-VPC platform, and has a default VPC with the identifier vpc-1a2b3c4d.

The Supported Platforms indicator

If your account supports only EC2-VPC, you can select a VPC from the Network list, and a subnet from the Subnet list when you launch an instance using the launch wizard.

Instance details: default VPC

EC2-Classic, EC2-VPC

The dashboard displays the following under Account Attributes to indicate that the account supports both the EC2-Classic and EC2-VPC platforms.

The Supported Platforms indicator

If your account supports EC2-Classic and EC2-VPC, you can launch into EC2-Classic using the launch wizard by selecting Launch into EC2-Classic from the Network list. To launch into a VPC, you can select a VPC from the Network list, and a subnet from the Subnet list.

For more information about how you can tell which platforms you can launch instances into, see Detecting Your Supported Platforms in the Amazon VPC User Guide.
