If you want to license access by users unaffiliated with UW-Madison, you would buy an External Connector license to license one server for an unlimited number of external users. Since UW-Madison is already licensed for Windows Server CALs, you generally don't need to purchase CALs.However, if you can limit Windows Server VMs to specific hosts (using VMWare's VM-Host Affinity Rule or similar techology), you would only have to license the cores in the hosts to which the servers are restricted.If you have Windows Server VMs running on multiple physical hosts, all of the cores in all of the physical hosts must be licensed.

More cores would require additional purchases.

Microsoft enforces a minimum purchase of eight of the license SKUs per server, which licenses up to 16 cores in one machine.

Each of the Windows Server license SKUs available for purchase in the catalog licenses two cores in one physical server.

Windows Server licensing always references the physical cores (not processors, not CPUs, not virtual cores) of the machines being licensed.

Datacenter allows for unlimited virtualization, while Standard has a limit of two VMs (you can license an additional two VMs in Standard edition by re-licensing the server if you have more than a dozen or so VMs, licensing with Datacenter costs less).

The main difference between the Standard and Datacenter editions of Windows Server is virtualization rights.

RDS clients are not licensed, so if you want to use RDS, you have to purchase RDS user or device client access licenses (CALs) or external connector licenses.

RDS servers are licensed with Windows Server if you own a Windows Server license you're licensed to use an RDS server on the same machine.Windows Remote Desktop Services (RDS) also uses the server/client licensing model.All UW System faculty, staff, and students are licensed for client access to Windows Server under the terms of our Microsoft campus agreement, so in most cases you only have to purchase Windows Server licenses.In the server/client licensing model, both servers and clients connecting to the servers must be licensed. Windows Server uses the server/client licensing model.
