Microsoft Nano Server
The Nano Server is a new type of distribution of OS server that changes the concept of density in the data center. Will form a new Windows Server 2016 installation mode can only occupy 10 % of the space normally required by the core server images. The idea is to reduce not only the size but also the number necessary to reboot the machine and allow to exploit the hardware. Also the issue of security has had an eye in recent releases thanks also to the reduction in the number of applications installed on the virtual machine.
