Windows Server 2019 Insider Preview Build 17723 Released

Microsoft today released a new Insider Preview of Windows Server. This time it is Windows Server Build 17723. Officially known as Windows Server 2019, this release is now available for the Long-Term Servicing Channel (LTSC). The release contains both the Desktop Experience and Server Core in all 18 server languages, as well as a new build of the next Windows Server Semi-Annual Channel release in English. In addition, the preview version of Microsoft Hyper-V Server is included with this build.

The Insider Preview program for Windows Server allows customers to try out all the new features of the upcoming OS and provide feedback on them to Microsoft.

This new build of Windows Server 2019 Insider Preview Build 17713 includes the following new features.

System Insights

In this Insider build, you can add new predictive capabilities to System Insights, without requiring any OS updates. This functionality enables developers, including Microsoft and third parties, to create and deliver new capabilities mid-release to address the scenarios you care about. New developer documentation and resourcesare now available, which help you write your own custom capabilities.

Any new capability can integrate with and extend the existing System Insights infrastructure:

• New capabilities can specify any performance counter or ETW event, which will be collected, persisted locally, and returned to the capability for analysis when the capability is invoked.
• New capabilities can leverage the existing Windows Admin Center and PowerShell management planes. Not only will new capabilities be discoverable in System Insights, they also benefit from custom schedules and remediation actions.

Deploying Kubernetes on Windows Server

Kubernetes is a popular orchestration tool for containers (see What are Containers) that makes deployment and management intuitive, scalable, and effective. This includes built-in features such as:

• Scheduling: Given a container image and a resource request, find a suitable machine on which to run the container.
• Health monitoring: Watch for container failures and automatically reschedule them.
• Networking: Provide a network for coordinating containers to communicate across machines.
• Service Discovery: Enable containers to locate each other automatically even as they switch hosts or change IP addresses.
• Scaling: Add or remove container instances to match demand, either manually or automatically.

And much more! For guidance that walks you through how to install Kubernetes onto your on-premise Windows datacenter, please see How To Guide: Kubernetes for Windows Flannel (Host-Gateway).

Congestion Control with LEDBAT

Keeping a network secure is a never-ending job for IT Pros, and doing so requires regularly updating systems to protect against the latest threat vectors.  This is one of the most common tasks that an IT Pro must perform.  Unfortunately, it can result in dissatisfaction for end-users as the network bandwidth used for the update can compete with interactive tasks that the end user requires to be productive.

With Windows Server 2019, we bring a latency optimized, network congestion control provider called LEDBAT which scavenges whatever network bandwidth is available on the network, and uses it

For a full write up detailing this improvement, please see our announcement LEDBAT – Latency Optimized Background Transport
