Subnet resources represent the subnets for cloud-based virtual networks on a target cloud 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. You can include or exclude each discovered Subnet resource for the Platform resource.
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.
