Windows Server 2019 is the 9th version of Microsoft’s Windows Server operating system, which is part of the Windows NT family. After Windows Server 2016, it is the second version of the server operating system based on the Windows 10 platform. The first Windows Insider preview release was announced on March 20, 2018, and it was released internationally on October 2, 2018. On August 18, 2021, it was succeeded by Windows Server 2022.
Development and Release
On March 20, 2018, Microsoft announced the development and release of Windows Server 2019, and the first Windows Insider preview version was released on the same day. On October 2 of that year, it was made available to the general public.
On October 6, 2018, Microsoft delayed the delivery of Windows 10 version 1809 (build 17763) while they investigated a problem with user data being destroyed after an in-place update. It affected systems when data was remained at the original location after a user profile folder (e.g. Documents, Music, or Pictures) was moved to another location. Because Windows Server 2019 is based on the Windows version 1809 codebase, it was also taken off the market at the time, although it was re-released on November 13, 2018. In compliance with the new release date, the software product life cycle for Server 2019 was reset.
Windows Server 2019 has below new features:
- Container services:
- Support for Kubernets (stable; v1.14)
- Support for Tigera Calico for Windows
- Linux containers on Windows
- Storage Spaces Direct
- Storage Migration Service
- Storage Replica
- System Insights
- Shielded Virtual Machines
- Improved Windows Defender Advanced Threat Protection (ATP)
- Windows Admin Center
- OpenSSH included
At the time of its release, Microsoft Edge did not support Server 2019. Internet Explorer 11 is a “compatibility layer,” not a browser, according to Microsoft. Edge added support in January 2020, although it is not installed by default in Server 2019. Edge is recommended for server and enterprise users by Microsoft.
Windows Server 2019 Top Six Features
Hyper convergence, administration, security, containers, and other features are included in a preview of Windows Server 2019.
Many of the capabilities that will be accessible with Windows Server 2019 have already been used in live business networks, thanks to Microsoft’s change to a more progressive update of Windows Server, and here are a half-dozen of the best.
Hyper converged infrastructure for businesses (HCI)
Microsoft has completed three years of updates for its HCI platform with the release of Windows Server 2019. That’s because Microsoft’s new progressive upgrade schedule includes what it terms Semi-Annual Channel releases, which are incremental improvements that are released as they become ready. Then it makes a big release called the Long-Term Servicing Channel (LTSC) version every couple of years that includes all of the upgrades from the previous Semi-Annual Channel releases.
The LTSC Windows Server 2019 is scheduled out this fall, and members of Microsoft’s Insider programme can download it immediately.
While the essential components of HCI (compute, storage, and networking) have been upgraded with the Semi-Annual Channel updates, Windows Server 2019 is a key release for enterprises creating datacentres and high-scale software defined platforms.
HCI is now available on top of a set of components included with the server licence in the newest edition. This entails a backbone of Hyper-V-enabled servers that can dynamically expand or decrease capacity for workloads without causing disruption. (For more information on Microsoft HCI, click here.)
Windows Server 2019 GUI
The lack of a GUI for the Semi-Annual Channel versions of Windows Server 2016 surprised many businesses when they started rolling them out. Only Server Core (and Nano) GUI-less configurations were supported in the Semi-Annual Channel releases. IT pros will once again have their desktop GUI of Windows Server with the LTSC release of Windows Server 2019, in addition to the GUI-less server Core and Nano variants.
Microsoft will formally unveil Project Honolulu, a server management tool, with the introduction of Windows Server 2019. Project Honolulu is a centralised console that lets IT pros manage both GUI and GUI-less Windows 2019, 2016, and 2012R2 servers in their environments.
Early users have praised Project Honolulu’s administrative simplicity, which includes duties like performance monitoring (PerfMon), server configuration and settings, and the management of Windows Services that run on server platforms. This makes it easier for administrators to manage these duties across multiple servers in their environment.
Improvements in Security
Microsoft has continued to integrate built-in security features to assist enterprises in addressing a security management approach based on “expect breach.” Rather than expecting that firewalls on an enterprise’s perimeter will prevent all security breaches, Windows Server 2019 considers that servers and applications in the datacentre’s core have already been infiltrated.
Windows Server 2019 comes with Windows Defender Advanced Threat Protection (ATP), which evaluates typical security breach vectors and automatically prevents and informs users about suspected malicious threats. Many of the Windows Defender ATP features have been rolled out to Windows 10 users in recent months. The addition of Windows Defender ATP to Windows Server 2019 allows them to take advantage of data storage, network transport, and security-integrity components to protect Windows Server 2019 systems from compromise.
Smaller, more Efficient Containers
Organizations are increasingly reducing their IT operations’ footprint and overhead by replacing bloated servers with thinner, more efficient containers. Windows Insiders have benefited from increased compute density, which has improved overall application operations without requiring more hardware server systems or hardware capacity expansion.
The Server Core image in Windows Server 2019 is smaller and leaner, reducing virtual machine overhead by 50-80%. When a business can achieve the same (or greater) functionality in a much smaller picture, it can save money and increase the efficiency of its IT investments.
Windows Subsystem on Linux
Microsoft and Linux were rarely mentioned in the same phrase as complementary platform services a decade ago, but that has changed. Linux instances as virtual machines are openly supported in Windows Server 2016, and the new Windows Server 2019 edition makes significant progress by introducing a complete subsystem tailored for the operation of Linux systems on Windows Server.
The Windows Subsystem for Linux adds a layer of networking, native filesystem storage, and security controls to the basic virtual machine operation of Linux systems on Windows Server. It has the capability of enabling encrypted Linux virtual instances. Shielded VMs for Windows were given in the same way in Windows Server 2016, but native Shielded VMs for Linux are now available in Windows Server 2019.
Enterprises have discovered that container optimization, combined with the ability to run Linux natively on Windows Server hosts, can reduce costs by removing the requirement for two or three infrastructure platforms and running them instead on Windows Server 2019.
The majority of the “new features” in Windows Server 2019 have been introduced in upgrades over the last few years, so they aren’t exactly shocking. However, it also means that the features in Windows Server 2019 that were part of Windows Server 2016 Semi-Annual Channel releases have already been tried, tested, updated, and verified, so enterprises won’t have to wait six to twelve months for a bug repair service pack when Windows Server 2019 arrives.
This is a significant change that is assisting organizations in planning their adoption of Windows Server 2019 sooner than they might have in the past, and with significant improvements for enterprise datacenter’s in gaining the benefits of Windows Server 2019 to meet the security, scalability, and optimized data center requirements that are so Acclaimed needed in today’s fast-paced environments.
