The licensing rules that actually matter here.
Windows Server Standard and Datacenter are licensed per core: minimum 16 cores per server and 8 per processor, sold as core packs.
Every user or device that touches the server also needs a Windows Server CAL; Remote Desktop use needs RDS CALs on top.
Send us your host and user counts with the quote request — we confirm the core and CAL math before you pay for anything.
