- TLS 1.2 and 1.3 Support: Enhanced security for network communications, ensuring secure encrypted data transfers.
- Windows Defender Exploit Guard: Provides comprehensive protection against a variety of attack vectors, such as malware and zero-day exploits.
4. Hyper-V Enhancements
- Nested Virtualization: Enables virtualization of Hyper-V hosts, which allows for creating virtual machines within virtual machines (VMs), beneficial for testing and development environments.
- Storage Quality of Service (QoS): Helps ensure that virtual machines receive appropriate levels of storage performance by controlling the I/O throughput.
- VM Connect: A feature to provide more intuitive management for Hyper-V virtual machines by enabling easy access to VMs.
5. Networking Features
- Software-Defined Networking (SDN): This allows you to manage and automate your network infrastructure, improving the flexibility and efficiency of network management.
- DirectAccess and VPN Improvements: Enhanced secure remote access features, providing seamless connectivity for remote users.
- Network Controller: A centralized management solution for configuring and monitoring networking components in software-defined datacenters.
6. Windows Admin Center
- Centralized Management Console: A web-based management interface that allows administrators to manage all aspects of the server, including storage, networking, and virtual machines, from a single location.
- Remote Management: Administer servers remotely and perform common tasks like monitoring, diagnostics, and troubleshooting.
7. Improved Virtual Desktop Infrastructure (VDI)
- Windows Virtual Desktop: Integration with cloud-hosted desktop environments to enable scalable, cost-effective virtual desktop solutions for remote and virtual teams.
8. Container Support and Kubernetes Integration
- Windows Containers: Support for running Windows containers alongside Linux containers, offering more flexibility for mixed-environment applications.
- Kubernetes Integration: Full support for Kubernetes orchestration to deploy, scale, and manage containerized applications across environments.
9. Server Core and Nano Server
- Server Core Installation: A minimal installation option that reduces overhead by eliminating unnecessary components, reducing the attack surface and improving security.
- Nano Server (limited in 2019 version): A lightweight, headless installation for highly optimized environments, mainly in containerized and cloud-native workloads.
10. Improved Application Platform
- Windows Subsystem for Linux (WSL): Provides a compatibility layer for running Linux binary executables in Windows, enabling developers to run Linux tools and applications natively within Windows Server.
11. Failover Clustering Enhancements
- Cluster Sets: Support for large-scale clusters with the ability to create a group of clusters that work as a unified entity, increasing scalability and resilience.
- Cluster Validation: Enhanced tools for testing configurations and ensuring the cluster is correctly set up.
12. Licensing and Scalability
- Unlimited Virtualization: The Datacenter edition allows for unlimited virtualization rights, meaning you can run an unlimited number of virtual machines (VMs) on a physical server.
- Licensing Flexibility: The Datacenter edition provides more options for enterprises with large-scale server deployments and requires more powerful hardware for optimal performance.
13. Enhanced Performance
- Better CPU and Memory Optimization: Improvements in memory and CPU resource management, making it easier to scale workloads.
- Storage and Network Performance: Optimized for high-throughput, low-latency workloads, including storage and networking performance.
14. PowerShell 7 Support
- Advanced Automation: PowerShell 7 allows better automation of administrative tasks, enhancing scripting capabilities for server management.
These features make Windows Server 2019 Datacenter ideal for organizations that require advanced capabilities in virtualization, storage, security, and cloud integration, making it suitable for large enterprises with complex infrastructure needs.ase of management.
