    Windows Server version 1803 Semi-Annual Channel update

    Last week we announced that Windows Server 2019, the next release in the Long-Term Servicing Channel (LTSC), will be generally available in the second half of calendar year 2018. Today, we would like to give you an overview of the next Semi-Annual Channel release.

    Long-Term Servicing Channel and Semi-Annual Channel

    In September 2017, we released Windows Server version 1709, the first release in the Semi-Annual Channel. The Semi-Annual Channel has a faster release cadence and addresses feedback from many of you who want faster innovation every few months. This complements the Long-Term Servicing Channel where the release cadence is every 2-3 years.

    After the launch of Windows Server version 1709, we learned more from our customers and partners about how they were using the Semi-Annual Channel release. Based on telemetry and feedback that we received from the Windows Insiders program and production deployments, we learned that the Semi-Annual Channel is ideal for modern applications and innovation scenarios such as containers and micro-services while LTSC is the preferred release for core infrastructure scenarios such as software-defined datacenter and hyper-converged infrastructure (HCI). Based on this insight, moving forward, we’re focusing our efforts on specific scenarios for Semi-Annual Channel and LTSC as follows:

    Long-Term Servicing Channel Semi-Annual Channel
    Recommended scenarios General purpose file servers, first and third-party workloads, traditional apps, infrastructure roles, software-defined Datacenter, and Hyper-converged infrastructure Containerized applications, container hosts, and application scenarios benefiting from faster innovation
    New releases Every 2–3 years Every 6 months
    Support 5 years of Mainstream support
    + 5 years of Extended support
    18 months
    Editions All available Windows Server editions Standard and Datacenter editions
    Who can use All customers through all channels Software Assurance and cloud customers only
    Installationoptions Server Core and Server with Desktop Experience Server Core for container host and image and Nano Server container image

    LTSC and Semi-Annual Channel carry an equal amount of importance to us. We will continue to listen to our customers and partners and build features and functionality in the two releases that fit the adoption pattern of our customers.

    Windows Server, version 1803 – the next Semi-Annual Channel release

    We are excited to tell you that the next version in the Semi-Annual Channel, Windows Server, version 1803, will be available soon. The Semi-Annual Channel enables us to drive rapid innovation and evolution through the full operating system and software stack which is vital to the success of solutions like Docker, Kubernetes, and Service Fabric.

    Below are a few features that we are excited about in Windows Server, version 1803. You may have already experienced these in the Windows Insider Program:

    • Server Core container images: We reduced the Server Core base container image by 30% from Windows Server, version 1709 and improved application compatibility – that will help customers containerizing existing applications.
    • Curl.exe, Tar.exe, and SSH support: Support for such tools will complement PowerShell for building and debugging scenarios.
    • Windows Subsystem for Linux (WSL): WSL has enabled server administrators to use existing tools and scripts from Linux on Windows Server. Many improvements showcased in the command line blog are now part of Windows Server including Background tasks, DriveFS, WSLPath, and much more.
    • Container networking enhancements: We added localhost and http proxy support while also improving container scalability and startup time.
    • Kubernetes journey: Working with-in and alongside the Kubernetes community, we enabled more of the Kubernetes feature set and ecosystem such as the following:
      • Addition of two storage plugins enabling persistent storage for Windows containers orchestrated by Kubernetes.
      • Cloud scale networking though initiatives like our partnership with Tigera on Project Calico support.
      • Windows platform support for Hyper-V isolated Pods (supporting multiple containers per Pod) which enhances container isolation and security in Kubernetes environments.

    We have more coming to Windows Server, version 1803 and you can check all the new features added to the preview builds in the Insiders space in the Windows Server Tech Community.

    You can try it all today!

    The good news is that you can try both, the next Semi-Annual Channel and the next LTSC release right now. Windows Server, version 1803 preview and Windows Server 2019 preview are available through the Insiders program. Don’t forget to give us feedback through the Windows Feedback Hub app.

    Frequently asked questions

    Q: When will Windows Server, version 1803 will be generally available?
    A: Windows Server, version 1803 will be available in the first half of calendar year 2018. We’ll share the general availability (GA) date soon.

    Q: Will HCI and SDDC features be available in the Semi-Annual Channel release?
    A: The Semi-Annual Channel releases will focus on modern application platform and other innovation scenarios such as containers and micro-services. While some infrastructure roles, such as Hyper-V, may be available, the full range of HCI and SDDC scenarios will be the focus of the LTSC channel and not the Semi-Annual Channel. Windows Server 2016, the latest LTSC release, is the recommended version today for Storage Spaces Direct and HCI scenarios. You can also check the Windows Server Software Defined (WSSD) program for validated designs.

    Q: Do I have to wait for Windows Server 2019 to test new infrastructure roles, Storage Spaces Direct, SDDC scenarios?
    A: No. The preview for Windows Server 2019, the next LTSC release, is already available through the Windows Insiders program.
