The Datacenter edition is also a big step up in the number of virtual machines, because the Datacenter Edition offers unlimited virtual machines, and just like the standard edition one Hyper-V host per license. This edition also supports shielded virtual machines.
Microsoft Windows Server 2022 Data Center: Azure Edition
