On March 20, Microsoft announced the release of the next official release of Windows Server this year, featuring enhanced support for hybrid workloads, Linux, and hyper-converged infrastructures.

Windows Server 2019 will replace Windows Server 2016, which was officially released in October 2016. Given that Microsoft switched to Windows Server updates twice a year last year, these updates go out on the long-term service channel every two to three years. This service model is for administrators who prefer to upgrade systems less frequently.


Those companies that have not yet switched to a six-month channel will be able to test the Linux and Kubernetes support technologies in Windows Server, which are now in beta.

Windows Server 2019 will streamline on-premises collaboration with Microsoft cloud services such as Azure Backup, Azure File Sync, and Disaster Recovery. This approach is part of Microsoft's broader view of on-premises hardware, playing the role of border nodes for company cloud systems, allowing administrators to transfer workloads between private and public environments.

Developers and administrators interested in using containers for their applications will have what to expect from Windows Server 2019. In particular, Microsoft plans to reduce the size of the Server Core container image to about 1.7 GB, which is significantly less than the current size of this image, which is 5 GB . Reducing the size of the image will simplify the optimization of the efficiency of workloads and will be a step towards those users who complained about the lack of more flexible images.

In addition, Microsoft said that the new release will improve the capabilities related to working with Kubernetes, the popular open source software for container orchestration, in the Windows Server environment. Now support for this technology in Windows Server is in beta, and Microsoft plans to significantly improve the capabilities of clusters running on this OS.
In addition, it is expected that this update will bring several improvements to the execution of tasks solved by Linux, including support for shielded virtual machines. These virtual machines offer customers an environment that is designed to be protected from malicious administrators or from administrators whose accounts are hacked. In addition, Microsoft is working to help users port their Linux scripts to Windows Server 2019, which translates into improved support for OpenSSH, Curl, and Tar.
In addition to Linux security updates, Microsoft is also integrating Windows Defender Advanced Threat Protection technology into Windows Server 2019. This is expected to help users in detecting and fixing security holes before they become large-scale problems.

If you're eager to try out Windows Server 2019, you can do it now using the Windows Insider Program. The release of this OS on the long-term service channel is expected in the second half of this year, along with the release of relevant updates on the semi-annual release channel. Microsoft plans to reveal further details about all of these updates in the coming months.
