Windows Server 2016[1] is an upcoming server operating system developed by Microsoft as part of the Windows NT family of operating systems, developed concurrently with Windows 10. The first early preview version (Technical Preview) became available on 1 October 2014 together with the first technical preview of System Center,[2] and is currently in public beta testing. The final release date for the server is expected to be in Q3 2016,[3] that is, not released simultaneously with the client operating system Windows 10 as was the case with the last three operating system releases.

Features

Windows Server 2016 has a variety of new features, including

  • Active Directory Federation Services: It is possible to configure AD FS to authenticate users stored in non-AD directories, such as X.500 compliant Lightweight Directory Access Protocol (LDAP) directories and SQL databases.[4]
  • Windows Defender: Windows Server Antimalware is installed and enabled by default without the GUI, which is an installable Windows feature.[5]
  • Remote Desktop Services: support for OpenGL 4.4 and OpenCL 1.1, performance and stability improvements; MultiPoint Services role (see Windows MultiPoint Server)[6]
  • Storage Services: central Storage QoS Policies; Storage Replicas (storage-agnostic, block-level, volume-based, synchronous and asynchronous replication using SMB3 between servers for disaster recovery).[7] Storage Replica replicates blocks instead of files; files can be in use. It's not multi-master, not one-to-many and not transitive. It periodically replicates snapshots, and the replication direction can be changed.
  • Failover Clustering: cluster operating system rolling upgrade, Storage Replicas[8]
  • Web Application Proxy: preauthentication for HTTP Basic application publishing, wildcard domain publishing of applications, HTTP to HTTPS redirection, Propagation of client IP address to backend applications[9]
  • IIS 10: Support for HTTP/2
  • Windows PowerShell 5.0[10]
  • Soft Restart, a Windows feature to speed up the booting process by skipping hardware initialization, and resetting software only.[11]

Networking features

Hyper-V

  • Rolling Hyper-V cluster update: unlike upgrading clusters from Windows 2008 R2 to 2012 level, Windows Server Technical Preview cluster nodes can be added to a Hyper-V Cluster with nodes running Windows Server 2012 R2. The cluster continues to function at a Windows Server 2012 R2 feature level until all of the nodes in the cluster have been upgraded and the cluster functional level has been upgraded.[19]
  • Storage quality of service (QoS) to centrally monitor end-to-end storage performance and create policies using Hyper-V and Scale-Out File Servers
  • New, more efficient binary virtual machine configuration format (.VMCX extension for virtual machine configuration data and the .VMRS extension for runtime state data)
  • Production checkpoints
  • Hyper-V Manager: alternate credentials support, down-level management, WS-Management protocol
  • Integration services for Windows guests distributed through Windows Update
  • Hot add and remove for network adapters (for generation 2 virtual machines) and memory (for generation 1 and generation 2 virtual machines)
  • Linux secure boot
  • Connected Standby compatibility
  • Storage Resiliency feature of Hyper-V is formed for detecting transitory loss of connectivity to VM storage. VM's will be paused till the time the connectivity is re-established.[20]

Nano Server

Microsoft announced a new installation option, Nano Server, a minimal footprint installation option of Windows Server. It excludes the graphical user interface, WoW64 (support for 32-bit software) and Windows Installer. It does not support console logon, either locally or via Remote Desktop Connection. All management is performed remotely via Windows Management Instrumentation (WMI) and PowerShell. Microsoft engineer Jeffrey Snover claims that Nano Server had 93 percent lower VHD size, 92 percent fewer critical security advisories, and 80 percent fewer reboots than Windows Server.[21][22]

Development

Microsoft has been reorganized by Satya Nadella, putting the Server and System Center teams together. Previously, the Server team was more closely aligned with the Windows client team. The Azure team is also working closely with the Server team.[23]

Releases

Preview releases

<templatestyles src="Module:Hatnote/styles.css"></templatestyles>

A public beta version of Windows Server 2016 (then still called vNext) branded as "Windows Server Technical Preview" was released on October 1, 2014; the technical preview builds are aimed toward enterprise users. The first Technical Preview was first set to expire on 15 April 2015 but[24] Microsoft later released a tool to extend the expiry date, to last until the second tech preview of the OS in May 2015.[25] The second beta version, "Technical Preview 2", was released on May 4, 2015. Third preview version, "Technical Preview 3" was released on August 19, 2015. "Technical Preview 4" was released on November 19, 2015. "Technical Preview 5" was released on April 27, 2016.

Public release

Windows Server 2016 is expected to be released to manufacturing in Q3 2016.[3] Unlike its predecessor, Windows Server 2016 is licensed by the number of CPU cores rather than number of CPU sockets—a change that has similarly been adopted by BizTalk Server 2013 and SQL Server 2014.[26]

  • Nano Server supports the DNS Server and IIS server roles, as well as MPIO, VMM, SCOM, DSC push mode, DCB, Windows Server Installer, and the WMI provider for Windows Update. Its Recovery Console supports editing and repairing the network configuration. A Windows PowerShell module is now available to simplify building Nano Server images.[33]
  • Hyper-V Containers encapsulates each container in a light weight virtual machine.[33]
Latest preview version of a future release: 10.0.14300 Technical Preview 5[34] April 27, 2016
  • Mostly general refinements. Greater time accuracy in both physical and virtual machines.
  • Container support adds performance improvements, simplified network management, and support for Windows containers on Windows 10.
  • Nano Server: an updated module for building Nano Server images, including more separation of physical host and guest virtual machine functionality as well as support for different Windows Server editions. Improvements to the Recovery Console, including separation of inbound and outbound firewall rules as well as the ability to repair configuration of WinRM.
  • Networking: traffic to new or existing virtual appliances can now be both mirrored and routed. With a distributed firewall and Network security groups, this enables dynamically segmented and secure workloads in a manner similar to Azure. One can deploy and manage the entire Software-defined networking (SDN) stack using System Center Virtual Machine Manager. Docker can be used to manage Windows Server container networking, and associate SDN policies not only with virtual machines but containers as well.

    • New "Encryption Supported" mode that offers more protections than for an ordinary virtual machine, but less than "Shielded" mode, while still supporting vTPM, disk encryption, Live Migration traffic encryption, and other features, including direct fabric administration conveniences such as virtual machine console connections and Powershell Direct.
    • Full support for converting existing non-shielded Generation 2 virtual machines to shielded virtual machines, including automated disk encryption.
    • Shielded virtual machines are compatible with Hyper-V Replica.
