The server builds on the Microsoft Azure platform and takes Microsoft deeper into their Cloud strategy.
If you like Server Core then you will love the Microsoft Nano Server feature which has a much smaller thumbprint and is designed to be used with the latest version of PowerShell ( 5.0) and to run Hyper-V clusters, ‘Scale-Out File Servers’, and cloud service apps.
Although not ready for our preview, apps can be in Windows Server Containers and Hyper-V Containers which are designed to separate them from the OS.
They claim Nano Server will have a 93% smaller virtual hard drive (VHD) size size, 92% fewer critical bulletins and 80% fewer required reboots and heavily increased scalability. 80% fewer reboots has got to be good.
