A tenant administrator or business group manager selects one or more Amazon instance types when creating Amazon EC2 blueprints. An IaaS administrator can add or remove them.

An Amazon EC2 instance is a virtual server that can run applications in Amazon Web Services. Instances are created from an Amazon machine image and by choosing an appropriate instance type.

To provision a machine in an Amazon Web Services account, an instance type is applied to the specified Amazon machine image. The available instance types are listed on the Amazon EC2 blueprint.

When creating an Amazon EC2 blueprint, you identify one or more instance types to be available for selection by the user when they provision a machine. The instance types must be supported in the designated region.
