For Amazon Web Services platforms, Subnet resources represent the subnets for virtual private clouds on a target AWS platform. Use the cloud vendor portal to segment your virtual network into one or multiple subnets and allocate a portion of the virtual network’s address space to each of its subnets. Subnet information for a platform is compiled through discovery.
NOTE:PlateSpin Transformation Manager does not currently support planning for AWS. For AWS Subnets, you can perform only those management actions appropriate for Manual (tracking) mode.
