Windows Server 2019 - First Preview
With a public pre-release version of Windows Server 2019, Microsoft is providing a first insight into the current state of development of its new server operating system. Windows Server 2019 will be the next release in the Long Term Servicing Channel (LTSC), which, in contrast to the Windows Server Semi Annual Channel (SAC), will only receive long-term security patches and no new features. Comparable to Windows 10, the SAC-version gets new features every six months and is supported for 18 months.
Key innovations in Windows Server 2019 include the introduction of cluster sets, a new cloud-scale-out technology that significantly increases the number of cluster nodes in a Software Defined Data Center (S2DC), and the integration of Windows Advanced Threat Protection and security technologies Windows Defender Exploid Guard. In addition, the new graphical management tool will be available from hybrid cloud scenarios. Project Honolulu is currently only in a preview.
Those interested in testing the Preview Build must register for the Insider Program. The final release will go live in October 2018, presumably at the same time as the upcoming major feature update for Windows Server version 1809. Windows Server 2019 is primarily intended for workloads such as Windows Server 2019. SharePoint Server, MS SQL Server, Exchange or Remote Desktop Session Host environments.
