The slimmed down version of Windows Server is destined for use in Azure’s Managed Disks. This is a storage option that allows the creation of disks without first creating a storage account and without the need to manually assign a universal resource indicator.
Microsoft offers Managed Disks at 32GB, 64GB, 128GB, 512GB and a terabyte, with the two smallest sizes a recent addition. But it looks like users had trouble squeezing Windows into the little ones, because Microsoft’s now announced it has “added a second set of Windows Server offerings with 30GB OS disks for Windows Server 2008R2, Windows Server 2012, Windows Server 2012R2 and Windows Server 2016”.
Microsoft channel partners can now put it into 32GB Managed Disks and save customers “US$2.18 per VM if you choose to deploy with 32GB Standard Managed OS disk vs. 127GB”.
Windows Server 2012 could be installed onto a 32 GB partition that was an absolute minimum value needed for successful installation. It was providing a Windows Server Core with IIS and no GUI, which was not very useful.
The new Azure version, though, makes it fit rather well into the tighter partition which makes it an easier sale.
