The Current State Windows Server 2019 

windows server 2019Windows Server 2019 is released! Microsoft’s Windows Server team is working hard on preparing the 2019 release. They’ve already released several new features in the past months as well as multiple refinements geared toward a polished end product. 

The Final Stages 

If you’re considering becoming an expert on the product for employability or transactions purposes, if you’re thinking to release software for the new platform, or if you intend to utilize Windows Server 2019, this is the best time to get into it! 

Microsoft has been asking for feedback on two things that are important to make the product more customer friendly: 

  • Seamless upgrade: To make migration easier without going through a complicated process Microsoft created a test system. Microsoft is doing great work to make Windows Server 2019 upgrade friendly. They can improve if we tell them where it lacks.
  • Application compatibility: Compatibility is the major issue with any new software, especially for software developers and administrators responsible for critical business applications. Windows Server 2019 introduces significant changes to how Windows Server operated nearly since its introduction. Be prepared for significant changes!

Summary of Features in Windows Server 2019 

Some of the new features included are: 

  • HTTP/2 support.
  • Cubic (a “congestion control provider” to help regulate TCP traffic) support.
  • Software Defined Networking (SDN) is now integrated in Windows Server and controlled by Windows AdminCenter, no Virtual Machine Manager (VMM) is needed! 
  • High-performance SDN gateways
  • Deployment of Distributed Cluster Name Objects, allowing a CNO to concurrently hold an IP from each node rather than present a unique IP over the complete cluster
  • Direct utilization of SPI, I2C, GPIO, and UART/COM containers through specialized bus support for Windows Server containers
  • Failover Clustering no longer requires NT Lan Manager (NTLM)
  • SMB 1.0disabled by default 
  • Now included as part of the build the Windows Subsystem for Linux
  • Introducing Windows Defender Advanced Threat Protection
  • Windows Server 2019 includes version 4.7 of.Net Framework 


Standard Networking Enhancements 

The HTTP/2 and LEDBAT presentations are exciting to watch. Even in private home systems, we have long wanted a way to shape the way that various networking activities utilize the available networking bandwidth in an optimum way. 

Hyper-V Networking Enhancements 

Removing VMM or a third-party tool need to control the software-defined networking feature is a huge step. SDN is of great use to cloud and host providers as well as to large organizations that stretch the limits of VLANs. Still, SDN presents more than scalability; it also provides a higher degree of isolation. We have been using separate Hyper-V virtual switches for isolation, but those become complicated to use for multiple VMs, especially in clusters. Now, everyone can utilize SDN. 

Specialized Bus Support 

Multiple problems are address with server virtualization, but there are still a few restrictions to virtual-only deployments. Hardware peripherals are at the top of those restrictions. The newly introduced bus functionality in Windows Server containers may offer a solution. It won’t be full virtualization, but it grants the ability to run a hardware-dependent container on a general-purpose host. 

This feature concerns IoT challenges. It is still unclear if we can fit it inside existing hardware challenges. 

Security Enhancements 

Multiple points of security hardening in Windows Server 2019 presented in the feature notes. The two new and more particular changes are: 

  • SMB 1.0 disabled by default. The newer features of SMB shadow version 1.0. We can’t ignore the security implications of SMB 1.0 any longer. In 2016, Windows and Windows Server made SMB 1.0 passively prepared because Windows XP, Windows Server 2003, and some applications require it. Presently, Windows XP and Windows Server 2003 are out of support for several years, so there is no reason to continue to support SMB 1.0 by default.
  • No NTLM required for Failover Clustering. NTLM is easy to break with modern technologies. Practically, a cluster’s inter-node communication should be isolated from general network access. Still, that does not reduce the need to secure the network. It’s satisfying to see NTLM eliminated from cluster communications.

Windows Admin Center Enhancements for Hyper-V 

Several changes applied to Windows Admin Center. It appears that Microsoft has been working on the user experience (UX) of this tool. Moreover, WAC has extra control features across Hyper-V. 

Windows Server 2019 and Parallels RAS

Coming Soon: Parallels Remote Application Server (RAS) will be supporting Windows Server 2019 Standard and Datacenter Editions to host Parallels RAS infrastructure roles including Parallels RAS Secure Client Gateways and Publishing Agents along with utilizing RD Session and VDI capabilities enabling organizations to leverage the advantages of this new server OS fully.
