Windows Server 2019 Datacenter Features:

Windows Server 2019 Datacenter builds upon the foundation of Windows Server 2016 while introducing several new features and enhancements aimed at providing a more secure, scalable, and versatile platform for demanding workloads. Here's a breakdown of some key features:

Virtualization:

• Unlimited virtual machines: Unlike Standard edition, Datacenter allows running an unlimited number of virtual machines per server, ideal for consolidating workloads and maximizing hardware utilization.
• Shielded Virtual Machines: Provides enhanced security by creating isolated VMs protected from the underlying host and administrator access, suitable for sensitive workloads.
• Dynamic memory allocation: Allocate memory dynamically between running VMs for improved resource optimization and flexibility.

Storage:

• Storage Spaces Direct: Create highly available and scalable software-defined storage pools using local server storage, eliminating the need for dedicated storage arrays and reducing costs.
• Storage Replica: Replicate storage volumes synchronously or asynchronously for disaster recovery and data protection.
• ReFS (Resilient File System): Offers improved performance and resilience for large datasets compared to NTFS.

Networking:

• Software-Defined Networking (SDN): Deploy and manage virtual networks more efficiently and flexibly with features like network controllers and overlay networks.
• Hyper-V Network Virtualization: Create isolated virtual networks for improved security and multi-tenancy.
• DirectAccess: Provide remote users with seamless and secure access to internal network resources without VPN.

Security:

• Windows Defender Advanced Threat Protection (ATP): Enhanced endpoint protection against malware and other threats.
• Secure Boot: Helps prevent unauthorized operating systems from loading on UEFI-based systems.
• BitLocker Drive Encryption: Encrypt entire drives for data protection at rest.

Other features:

• Larger memory support: Supports up to 24 TB of RAM per server, ideal for memory-intensive workloads like databases and in-memory analytics.
• Clustering: Group multiple servers together for high availability and scalability.
• Windows Subsystem for Linux (WSL 2): Run Linux distributions directly on Windows Server for improved developer experience and hybrid deployments.
• Containerization support: Deploy and manage containerized applications with Docker and Kubernetes integration.
