Windows Server 2019

Windows Server 2019 builds on the foundation of Windows Server 2016, the fastest adopted version of Windows Server with 10s of millions of instances deployed worldwide. Windows Server 2019 bridges on-premises environments with Azure services, enabling hybrid scenarios that maximize existing investments. Increase security and reduce business risk with multiple layers of protection built into the operating system. Evolve your datacenter infrastructure to achieve greater efficiency and scale with Hyper-converged Infrastructure (HCI). Enable developers and IT pros to create cloud native applications and modernize their traditional apps using containers and micro-services.

Windows Server 2019 can help your Datacenter modernization which is critical to support your business and deliver innovation, especially given the competitive landscape of today. Windows Server 2019 is also a requirement to use Remote Desktop Services (RDS) for Office 2019.

Windows Server 2019 Focus Areas

Hybrid is built in to Windows Server 2019 and Windows Admin Center. To make it easier to connect existing Windows Server deployments to Azure services, there are interfaces for hybrid capabilities in the Windows Admin Center. With Windows Admin Center and Windows Server 2019, you can use hybrid features like Azure Backup, Azure File Sync, disaster recovery to extend your datacenters to Azure.
There is a three-fold approach on security with Windows Server 2019: Protect, Detect, and Respond. On the Protect front, there are Shielded VMs to protect sensitive virtualized workloads such as Domain Controllers, PCI data, sensitive healthcare, and financial data among others. This has been extended to Shielded VMs for Linux VMs. On the Detect and Respond front, there is Windows Defender Advanced Threat Protection (ATP), that detects attacks and zero-day exploits among other capabilities. Windows Server 2019 also includes Defender Exploit Guard to help you elevate the security posture of your IT environment and combat ransomware attacks.
In Windows Server 2019, the Server Core base container image has been reduced to a third of its size. App compatibility has been improved, support for Service Fabric and Kubernetes, and support for Linux containers on Windows to help modernize your apps. To address the complexity in navigating environments with Linux and Windows deployments, previously Microsoft extended Windows Subsystem for Linux (WSL) into insider builds for Windows Server, so that customers can run Linux containers side-by-side with Windows containers on a Windows Server. In Windows Server 2019, Microsoft is further improving WSL, helping Linux users bring their scripts to Windows while using industry standards like OpenSSH, Curl & Tar.

Windows Server 2019 has cost-effective high-performance software-defined storage and networking that allows deployments to scale from small 2-node, all the way up to 100s of servers with Cluster Sets technology, making it affordable regardless of the deployment scale.
