Windows Server 2019 is the latest version of Microsoft Windows Server. The current version of Windows Server 2019 improves on the previous Windows 2016 version in regards with better performance, improved security, and excellent optimizations for hybrid integration.
Below features are only available on Windows server 2019 compared to Windows server 2016.
Azure hybrid capabilities
System Insights – the built-in tool which proactively analysis the system data and alert the findings.
Azure network adaptor: Used to connect to Azure virtual networks.
Nested Mirror Accelerated parity: Two-node clusters which provide fault tolerance.
USB thumb drive as cluster witness: USB drive can be used as a cluster witness which allows true two node HCI deployments.
Deduplication for ReFS: This will save 90% disk space using de-duplication.
Cluster-wide monitoring: Monitor real time system performance related to Cluster.
Cluster sets: Now we can create large scale Cluster.
Persistent memory: PM provides byte level access to non-volatile memory to improve performance.
Virtual network peering: Now we can connect two virtual networks with High speed connectivity.
Improved SDN gateway: Improved site to site VPN connectivity.
Precision Time Protocol (PTP): Replacement for NTP (Network Time Protocol).
Leap Second support: Now Windows support the leap second changes.
Latency Optimized Background Transport: Network bandwidth management.
Enhanced Windows Defender Advanced Threat Protection (ATP): ATP now uses preventative protection, attack detection, and zero-day exploits.
Shielded VMs for Linux: More secure VMs.
HGS offline mode for shielded VMs: shielded VMs are more secure event HGS cannot be reached.
VM Connect for shielded VMs: Easy to manage shielded VMs.
Cluster hardening: Now Cluster works without NTLM.
SDN encrypted subnet: secure encrypted communication between VMs that communicate with each other within subnets.
Linux containers: Now we can manage Windows and Linux applications on the same environment.
Server Core base container image: Reduced container image size.
Server Core Features on Demand (FoD): Improved application compatibility.
Kubernetes platform support: Improves computing, storage, and networking components.
Windows Subsystem for Linux (WSL): Use Windows tools like Command Prompt and PowerShell from Linux.
Storage Migration Service: migrate the existing server to new hardware or new Operating system version.
