Windows Server 2016

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, that is, not released simultaneously with the client operating system Windows 10 as was the case with the last three operating system releases.

Features

• 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.[3]
• Windows Defender: Windows Server Antimalware is installed and enabled by default without the GUI, which is an installable Windows feature.[4]
• Remote Desktop Services: support for OpenGL 4.4 and OpenCL 1.1, performance and stability improvements; MultiPoint Services role (see Windows MultiPoint Server)[5]
• 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).[6] 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[7]
• 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[8]
• IIS 10: Support for HTTP/2
• Windows PowerShell 5.0[9]
• Soft Restart, a Windows feature to speed up the booting process by skipping hardware initialization, and resetting software only.[10]
• Telnet server is not included.

Networking features

• DHCP: as Network Access Protection was deprecated in Windows Server 2012 R2, in Windows Server 2016 the DHCP role no longer supports NAP[11]
• DNS:
  • DNS client: service binding – enhanced support for computers with more than one network interface[12]
  • DNS Server: DNS policies, new DDS record types (TLSA, SPF, and unknown records), new PowerShell cmdlets and parameters[13]
• Windows Server Gateway now supports Generic Routing Encapsulation (GRE) tunnels[14]
• IP address management (IPAM): support for /31, /32, and /128 subnets; discovery of file-based, domain-joined DNS servers; new DNS functions; better integration of DNS, DHCP, and IP Address (DDI) Management[15]
• Network Controller, a new server role to configure, manage, monitor, and troubleshoot virtual and physical network devices and services in the datacenter[16]
• Hyper-V Network Virtualization: programmable Hyper-V switch (a new building block of Microsoft’s software-defined networking solution); VXLAN encapsulation support; Microsoft Software Load Balancer interoperability; better IEEE Ethernet standard compliancy[17]

Hyper-V[18]

• 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.
• 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

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, neither locally nor 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.[19][20]

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.[21]

Releases

Preview releases

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 towards enterprise users. The first Technical Preview was first set to expire on 15 April 2015 but[22] Microsoft later released a tool to extend the expiry date, to last until the second tech preview of the OS in May 2015.[23] 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.

Public release

Windows Server 2016 is expected to be released to manufacturing sometime in 2016.[24] 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.[25]
