Windows Server 2016 is now generally available for use. As we have come to expect from new versions of Windows Server, this is newest release of Microsoft’s server operating system, generally came to exist on September 26, along with System .The list of new features in Windows Server 2016 is staggering, but 10 stand out.
The biggest change in Windows server is the new Nano Server. It has 92 percent smaller installation and 80 percent fewer required reboots than the GUI. It is designed to run Hyper-V cluster, and Scale-Out file Servers and cloud service applications. A Nano server must be managed remotely and can only run 64 bit applications.
2. Windows Server Container &Hyper-V Container.
The container type is intended for low-trust workloads where Container instances running on the same Server may share some common resources. Instead, it is a “super isolated” containerized Window Server. Hyper-V containers are appropriated for high-trust workloads.
Docker is an open source engine which is used for building, running and managing containers. Docker containers were originally built for Linux. You can use it to manage Windows Server and Hyper-V Containers.
4.Rolling upgrades for Hyper-V and Storage cluster
This new rolling upgrades feature allows to add a new Windows Server 2016 node to a Hyper-V cluster that were running in Windows Server 2012. The cluster will continue to run on Windows Server 2012 functional level until all of the cluster nodes have been upgraded to Windows Server 2016.
5.Hot add & remove of virtual memory network adapters
Another great new feature in Windows Server 2016 Hyper-V is the ability to add and remove virtual memory and also virtual network adapters while the virtual machine is running. In previous version releases you were supposed to use dynamic memory to change minimum and maximum RAM (Random access memory) settings of a VM that is running. You can add and remove network adapters while VM is running.
This is added primarily for the new container support, Windows Server 2016’s nested virtualization capabilities is a handy addition for training and lab scenarios. There is no limit to run the Hyper-V role on a physical server. Nested virtualization even enables you to run Hyper-V within a Hyper-V virtual machine.
PowerShell is a great management automation tool but it can be bit complicated to run remotely against your VMs. Do not worry about security policies, firewall configurations and your host networking configuration. This enables you to run PowerShell commands on the guest OS of a VM without need of network layers. It connects directly to the guest VM and all you need is authentication credentials for the VM’s guest OS.
8.Linux Secure Boot
This new feature has the ability to enable secure boot for VMs with Linux guest operating systems. Secure Boot is a feature of the UEFI (Unified Extensible Firmware Interface) firmware specification incorporated in generation 2 VMs which protects the VM’s hardware kernel mode code from being attacked by root kits and other boot-time malwares.
9.New Host Guardian Service and Shielded VMs
This is a new role which enables shielded virtual machines and also protects the data on from unauthorized access even from Hyper-V administrators. Shielded VMs are created by Azure Management Pack Portal. Standard VMs can also be converted to Shielded VMs.
10.Storage Spaces Direct
Storage Spaces Direct is the evolution of the old Storage Spaces technology found in Windows Server 2012. Windows Server 2016 Storage Spaces Direct allows you a cluster to access JBOD (just a branch of disks) storage in an external enclosure like Windows Server 2012 or it can also allow access to JBOD that are internal to the cluster nodes.
