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.
- Windows Defender: Windows Server Antimalware is installed and enabled by default without the GUI, which is an installable Windows feature.
- Remote Desktop Services: Support for OpenGL4 and OpenCL1.1, performance and stability improvements; MultiPoint Services role (see Windows MultiPoint Server)
- Storage Services: Central Storage QoS Policies; Storage Replicas (storage-agnostic, block-level, volume-based, synchronous and asynchronous replication using SMB3between servers for disaster recovery). 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
- 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
- Windows PowerShell 5.1
- Windows Server Containers
- DHCP: As Network Access Protection was deprecated in Windows Server 2012 R2, in Windows Server 2016 the DHCP role no longer supports NAP
- DNS client: Service binding – enhanced support for computers with more than one network interface
- DNS Server: DNS policies, new DDS record types (TLSA, SPF, and unknown records), new PowerShell cmdlets and parameters
- Windows Server Gateway now supports Generic Routing Encapsulation(GRE) tunnels
- 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
- Network Controller: A new server role to configure, manage, monitor, and troubleshoot virtual and physical network devices and services in the datacentre
- Hyper-V Network virtualization: Programmable Hyper-V switch (a new building block of Microsoft’s software-defined networkingsolution); VXLAN encapsulation support; Microsoft Software Load Balancer interoperability; better IEEE Ethernet standard compliance.
- Rolling Hyper-Vcluster update: Unlike upgrading clusters from Windows 2008 R2 to 2012 level, Windows Server 2016 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
- Storage Resiliency feature of Hyper-V is formed for detecting transitory loss of connectivity to VM storage. VMs will be paused until connectivity is re-established.
- RDMA compatible Virtual Switch
