Microsoft Windows Server 2019 Release- What's new in???


Microsoft Windows Server 2019- What's new in???


After successful release of windows 2016, Microsoft announced Windows Server 2019 in March 18 with Preview available, now this is the right time to understand all available editions with it and what all new things introduced along with it.



What about the available editions of Window Server 2019? Did anything change since the previous release? And answer is yes . The Storage Server Editions are not anymore, an option.
Windows Server 2019 is the first version to skip the classic Release To Manufacturing (RTM) milestone and go directly to General Availability (GA). This change is motivated by the increasing popularity of virtual machines, containers, and deploying in the cloud. But it also means the hardware ecosystem hasn’t had the chance to validate and certify systems or components before the release; instead, they start doing so today.

Windows Server 2019 Build version 

Microsoft first announced that Windows Server 2019 in Mar 2018 - along with its counterpart, Windows Server, version 1809. But unfortunately, all versions of Windows 10 version 1809 were pulled due to quality issues, but now they are back. Microsoft is officially re-releasing both Windows Server 2019 and Windows Server, version 1809.

The difference between Windows Server 2019 and version 1809 is that the former is from the Long-Term Servicing Channel (LTSC) and the latter is from the Semi-Annual Channel (SAC). LTSC releases are every three years, while SAC releases are, well, semi-annual. That also means that updates are delivered differently, as those on version 1809 will get the next feature update, which should now just be five months away.

The features included in Windows Server 2019 are those that the Semi-Annual Channel have had for a while, but Windows Server 2016 hasn't received yet. It's meant to bridge the gap between on-premises servers and Azure services for a hybrid environment. Windows Admin Center 1809 should also be re-released now.

with windows server 2019 Microsoft introduced new feature called System Insights, it brings local predictive analytics capabilities  to Windows Server. These predictive capabilities, each backed by a machine-learning model, locally analyze Windows Server system data, such as performance counters and events, providing insight into the functioning of your servers and helping you reduce the operational expenses associated with managing issues in your Windows Server deployments.


Software Defined Networking (SDN)- Security

Security with SDN delivers many features to increase customer confidence in running workloads, either on-premises, or as a service provider in the cloud.
These security enhancements are integrated into the comprehensive SDN platform introduced in Windows Server 2016. with release of windows server 2019 below updated/new features has been introduced.

  • Network Encryption
  • Firewall Auditing
  • Virtual network peering
  • Egress Metering
High performance SDN gateways in Windows Server 2019 greatly improves the performance for IPsec and GRE connections, providing ultra-high-performance throughput with much less CPU utilization. with Windows Server 2019, it’s easy to deploy and manage through a new deployment UI and Windows Admin Center extension that enable anyone to harness the power of SDN.

HTTP/2

Windows 2019 introduced HTTP/2 for a faster and safer Web, Improved coalescing of connections to deliver an uninterrupted and properly encrypted browsing experience.Upgraded HTTP/2’s server-side cipher suite negotiation for automatic mitigation of connection failures and ease of deployment. Changed default TCP congestion provider to Cubic to give you more throughput!

Storage Migration Service

Storage Migration Service is a new technology that makes it easier to migrate servers to a newer version of Windows Server. It provides a graphical tool that inventories data on servers, transfers the data and configuration to newer servers, and then optionally moves the identities of the old servers to the new servers so that apps and users don't have to change anything. 

Failover Clustering

Many changes and new options introduced with windows server 2019 Failover Cluster, below are list of major changes.
  • Failover Cluster no longer uses NTLM authentication
  • USB witness
  • Cluster infrastructure improvements
  • Cluster Aware Updating supports Storage Spaces Direct
  • File share witness enhancements
  • Cluster hardening
  • Cluster sets
  • Azure-aware clusters
  • Cross-domain cluster migration

Support for Kubernetes

Windows Server 2019 continues the improvements to compute, networking and storage from the semi-annual channel releases needed to support Kubernetes on Windows. More details are available in upcoming Kubernetes releases. Container Networking in Windows Server 2019 greatly improves usability of Kubernetes on Windows by enhancing platform networking resiliency and support of container networking plugins. Deployed workloads on Kubernetes are able to use network security to protect both Linux and Windows services using embedded tooling.
improved integrated identity windows authentication in containers easier and more reliable, addressing several limitations from prior versions of Windows Server. Containerizing Windows-based applications just got easier, the app compatibility for the existing windowsservercore image has been increased. For applications with additional API dependencies, there is now a third base image windows. The base container image download sizes, size on disk and startup times have been improved. This speeds up container workflows. It made it easier than ever to see which containers are running on your computer and manage individual containers with a new extension for Windows Admin Center.

Improved Network Performance for virtual workloads

Network performance improvements for virtual workloads maximizes the network throughput to virtual machines without requiring you to constantly tune or over-provision your host. This lowers the operations and maintenance cost while increasing the available density of your hosts. These new features are, Receive Segment Coalescing in the vSwitch and Dynamic Virtual Machine Multi-Queue (d.VMMQ).

There are many small update and new features introduced in windows server 2019, but above are some major changes and new features.

Enjoy with new Windows server 2019 build....................
