Microsoft continues to launch new previews of Windows Server 2016 with new features. In the latest version, Technical Preview 3, is introduced including integration with Docker and Windows Server containers. InfoWorld has listed some of the best news.
Containers
Containers will be big in the near future, and Windows Server 2016 supports two types of them. Partly Windows Server container, which uses the same concept as Docker where each container is running as an application in the operating system, and Hyper-V containers. The latter will act as completely isolated virtual machines with their own version of the Windows kernel, but more lightweight than traditional Hyper-V containers.

Nano Servers
Nano Server is significantly minimized version of Windows Server, which only uses about 512 MB of hard drive and 256 MB of memory. The idea is that these small server versions should work well as host systems for the virtual machines and the server system itself can only operate using Windows PowerShell, or the like. The Technical Preview 3 also introduces the Emergency Management Console Nano server, making it possible for instance to resolve network problems directly in the server.
Storage Replica
Windows Server already supports replication, but have so far been limited to asynchronous replication. In Windows Server 2016, it will also be possible to replicate entire volumes at the block level and the choice between synchronous or asynchronous replication.
Storage replica will , above all do benefit when a ‘ “Threats replica” -Backup needed in case something goes horribly wrong. Both the server-to-server and cluster-to-cluster replication supported.
New file system Refs default
Resilient File System (Ref) introduced back in Windows 8 and Windows Server 2012, but the old NTFS was still the default choice. In Windows Server, however, the new file system to be the default selection. Besides Refs are more resistant to damage to the file system, it also works very well with Hyper-V. Prestandaförbättrningar just for Hyper-V, for example, will make it possible to create virtual machines with fixed size basically as fast as you can press the enter key. The same applies, even in the creation of the checkpoint files and mergers VHDX files.
Rolling updates for Hyper-V
At last you avoid having a separate machine to update the operating system. Windows Server 2016, to support rolling updates from Windows Server 2012 R2. In other words, you do not close any cluster, or migrate to new hardware at each update. Important to remember is that the cluster functionally will act as the Windows Server 2012 R2 to all hosts in the cluster are upgraded to Windows Server 2016.

Add to that that it is also possible to add network adapters and memory to virtual machines even when they run, which was not possible previously.
Upgrades for network management
Windows Server 2016 will have many upgrades for network administrators. One new feature is Network Controller, which functions as a central location to manage network infrastructure and services. The key word for the new server version is convergence. New features make it possible to combine different network interface, which in theory would make it possible to halve the number of network ports in some cases.
