What Are the New Features in Windows Server 2019

         

 

            Microsoft introduces new and creative technologies with each successive edition of Windows Server to improve management or add critical functionality. This version of Windows Server has received considerable improvements, as is customary. It has numerous new features and enhancements. Some of the new features in Windows Server 2019 are as follows:

 

Container-Related Services

 

        Kubernetes Support Is Built-in

 

          To enable Kubernetes on Windows, Windows Server 2019 builds on Semi-Annual Channel advancements to computation, networking, and storage. By strengthening platform networking resiliency and supporting container networking plugins, Container Networking in Windows Server 2019 dramatically increases Kubernetes usability on Windows. Embedded technology enables Kubernetes workloads to employ network security to protect both Linux and Windows services.

 

        Containers for Linux on Windows

 

            Windows and Linux-based containers can now be operated on the same container host using the same docker daemon. Also it allows you to have a heterogeneous container host environment while yet giving application developers flexibility.

Storage

 

          Changes to the storage area are also included in the latest version. Storage Migration Service is a brand-new feature in this release. This new feature aids in the migration of your servers to a more recent version of Windows Server. In addition, it also makes moving to the cloud a lot easier. Aside from that, Storage Space Direct has been improved. You can anticipate the server to be more stable and faster using this feature.

 

        Service for Storage Migration

 

            Storage Migration Service is a new technology that allows upgrading to a newer version of Windows Server to be more accessible. It provides a graphical interface for inventorying data on servers, transferring data and configuration to newer servers, and optionally moving the identities of the old servers to the new servers so that apps and users do not have to modify anything.

     Spaces for Direct Storage

 

• Deduplication and compression are utilized for ReFS volumes.

• Persistent memory support is built-in.

• Nested resiliency at the edge for two-node hyper-converged infrastructure

• Two-server clusters with a USB flash drive serving as a witness

• Assistance with the Windows Admin Center

• Performance history

• Scalability is possible up to 4 PB per Cluster.

• Mirror-accelerated parity is approximately two times as quick as ordinary parity.

• Detecting drive latency outliers. By manually limiting volume allocations, you can increase fault tolerance.

 

      Storage Replica

 

• Storage Replica is now included in Windows Server 2019 Standard Edition.

• Test failover is a new functionality that enables you to mount destination storage to analyze replication or backup data. Enhancements to the Storage Replica log’s performance Windows Admin Center supports validating replication or backup data.

       System Insights

 

System Insights is a new feature in Windows Server 2019 that brings native predictive analytics capabilities to Windows Server. They evaluate local Windows Server system data like performance counters and events to provide insight into how your servers are running and help you reduce the operational costs associated with reactively handling issues in your Windows Server deployments.

 

 

Security

 

      Windows Server 2019 now has new security features. This version includes a new set of host intrusion prevention features called Windows Defender Advanced Threat Protection (ATP). This proactive security feature scans the server for malware and disables any potentially dangerous activities. It is also capable of detecting attacks and zero-day exploits. This feature enables you to start your virtual machines even when HGS is unavailable.

 

Enhancements to Shielded Virtual Machines

 

       Improvements to Branch Offices

 

By using the new fallback HGS and offline mode features, you can now run shielded virtual machines on machines with intermittent access to the Host Guardian Service. If Hyper-V cannot connect to your primary HGS server, you can specify a backup set of URLs for it to try.

Offline mode allows you to start shielded VMs even when HGS is unavailable. As long as the VM was previously successfully started and the host’s security settings have not changed.

 

      Troubleshooting Has Been Improved

 

         We’ve also added VMConnect Enhanced Session Mode and PowerShell Direct support to help you troubleshoot your shielded virtual machines. These tools are handy if your virtual machine (VM) has lost network connectivity and needs to change its configuration to regain access.

These features are automatically activates when a shielded VM will be deploy on a Hyper-V host running Windows Server 1803.

 

       Compatibility with Linux

 

         Windows Server 2019 supports running Ubuntu, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server inside shielded virtual machines in mixed-OS environments.

 

HTTP/2 Enables a Quicker and More Secure Web

 

• Connections are better coalesce to ensure an uninterrupted and fully encrypted browsing experience.

• HTTP/2 server-side cipher suite negotiation has already have been improve for automatic connection failure mitigation and deployment ease.

• We’ve switched our default TCP congestion provider to Cubic to increase your throughput!

 

 

Windows Defender’s Advanced Threat Protection (ATP)

 

         Therefore, TP’s sophisticated platform sensors and response actions automatically detect and suppress memory and kernel-level threats, as well as malicious files and processes.

• Windows Defender ATP Exploit Guard is a new anti-host infiltration technology. So, the four components of Windows Defender Exploit Guard work together to protect the device against common malware attack paths and behaviors.

• Attack Surface Reduction is a collection of security controls that enterprises can use to prevent malware from infecting their computers. Blocking suspicious harmful files (such as Office files), scripts, lateral movement, ransomware behavior, and email-based threats are among the precautions.

• Network Protection for Windows Defender SmartScreen protects the endpoint against web-based threats by restricting the device’s outgoing processes to untrusted hosts/IP addresses.

• By blocking untrusted processes from accessing password-protected files, Controlled Folder Access protects against ransomware.

• A suite of vulnerability mitigations (which replaces EMET) that may be easily setup to protect your system and applications from exploitation.

• Windows Server 2016 introduced Windows Defender Application Control (a.k.a. the Code Integrity (CI) policy). Customer feedback indicates that it is a fantastic idea that is tough to implement. To address this, we created default CI rules that allow all Windows in-box files and Microsoft applications, such as SQL Server, will going to execute while prohibiting known CI bypass executables.

 

 

Administration

 

      Microsoft Windows Admin Center

 

        Servers, clusters, hyper-converged infrastructures, and Windows 10 personal computers may all be manage via Windows Admin Center. It is ready for production and requires no further hardware or software beyond Windows. Therefore, the Windows Admin Center is a management console for servers and clusters running Windows Server 2008 R2 and later, and Windows 10 and preceding Windows and Windows Server versions.

 

    SetupDiag Specifications

 

         So, SetupDiag is a diagnostic tool that can be used to ascertain the reason for a failed Windows 10 upgrade. It performs an examination of the files contained in the Windows Setup log. So, it decodes these log files to find out why the PC won’t update to Windows 10. SetupDiag can be run on the failed updated PC. Remotely run SetupDiag and export the machine’s logs.

 

      OpenSSH

 

          OpenSSH is the open-source version of the Secure Shell (SSH) utilities. Linux and other non-Windows administrators administer remote systems across platforms. In other words, OpenSSH have been integrated into Windows since the autumn of 2018 and is currently available in Windows 10 and Windows Server 2019. Certainly, SSH is a client-server protocol, with the client being the user’s system and the server being the remote system being administered. OpenSSH contains a number of components and utilities that make remote system administration safer and more manageable, including the following:

• The SSH server component of the remote management system, sshd.exe, must be running.

• ssh.exe is the SSH client component that is install on the local system of the user.

• ssh-keygen.exe is a command-line utility that produces, manages, and converts SSH authentication keys.

• ssh-agent.exe is a program that stores private keys for usage with public keys.

• The program ssh-add.exe modifies the server’s list of acceptable keys by adding private keys.

• ssh-keyscan.exe is a command-line application for obtaining public SSH host keys from a large number of hosts.

• SSH is use to connect to sftp.exe, a program that implements the Secure File Transfer Protocol (SFTP).

• SSH users can use scp.exe to copy files.

 

Azure, in Addition to the Hybrid Cloud

 

         Virtualization and hybrid clouds have grown ingrained in today’s information technology ecosystem.  Therefore, this edition of Windows strengthens the ties between Microsoft’s Azure cloud platform and the Windows Server operating system. So, the Azure Network adapter connects the local server’s cloud computing platform and the Admin Center. Azure Backup, File Sync, Disaster Recovery, and all other Azure services, and now supported more robustly in this release.

 

       Clustering Has Been Streamline

 

    In Windows Server 2019, clustering has been improved in the following ways:

 

                         Cluster Sets 

 

          So, it is a new technique that enables the grouping of multiple clusters. Therefore, they can be all-computing, all-storage, or hyperconverged (storage and compute). This allows you to migrate virtual machines (VMs), between clusters with little downtime for the VMs while performing maintenance. So, to utilize the Cluster Sets functionality, you must first create a virtual machine (VM) and point it to the unified namespace of the cluster set. Therefore, a file share that can be use to achieve quorum in clustering, while using the Distributed File System. As a result, the Failover Cluster Manager can avoid creating a file share witness (DFS). Assume, you try to mount your DFS file share witness. In that instance, you’ll get an error notice about cluster instability.
