Key Features:  

1. Advanced Multi-Layered Security

• Secured-Core Server: Windows Server 2022 introduces the Secured-Core functionality, leveraging hardware and firmware-level protection to defend against sophisticated cyber-attacks. It provides safeguards from vulnerabilities like firmware attacks and improves protection against rootkits.
• TPM 2.0 and Secure Boot: Trusted Platform Module (TPM) 2.0 is required, providing cryptographic-based security for boot processes, while Secure Boot helps block malicious firmware during system startup.
• HTTPS and TLS 1.3 by Default: Windows Server 2022 enables HTTPS and TLS 1.3 out of the box for encrypted communication, ensuring better performance and security of data in transit.

2. Azure Hybrid Integration

• Azure Arc Integration: With Azure Arc, Windows Server 2022 supports hybrid cloud environments, enabling centralized management of both on-premises and Azure-based resources. This gives businesses the flexibility to run applications in both cloud and on-prem infrastructure.
• Azure Automanage: A key hybrid feature allowing businesses to automate IT management tasks like configuration and monitoring for both Windows Server 2022 instances running on-premises and in Azure.
• Extended Cloud Features: Includes enhanced Azure Backup, Azure Monitor, and Azure Site Recovery to ensure continuity and manageability between on-prem servers and the cloud.

3. Improved Virtualization with Hyper-V

• Enhanced VM Performance: Windows Server 2022 improves performance for Windows and Linux-based VMs, offering better efficiency for virtualization tasks in enterprise data centers. It includes features like nested virtualization for both Windows and Linux.
• Storage Spaces Direct (S2D): This release includes improvements to Storage Spaces Direct, enabling highly available and scalable hyper-converged infrastructures (HCI). It also supports faster network speeds, including 100 Gbps networks.
• VM Encryption: VM encryption for Hyper-V is enhanced, making it easier to protect sensitive data inside VMs from unauthorized access.

4. Hybrid Cloud Storage and Backup

• Azure Stack HCI Integration: Windows Server 2022 offers full support for Azure Stack HCI, enabling hybrid storage and compute, optimized for workloads that need both cloud and on-prem infrastructure.
• SMB Compression: File transfers using the SMB protocol now support compression, reducing the amount of data sent over the network, improving performance and reducing the time for file transfers.
• ReFS Improvements: The Resilient File System (ReFS) in Server 2022 is further optimized for handling large datasets, offering better scalability and protection against data corruption.

5. High Availability and Scalability

• Cluster Sets: Windows Server 2022 introduces cluster sets, an extension of cluster management capabilities, which allow businesses to scale clusters across data centers more efficiently. This helps improve high availability and performance in large infrastructures.
• Hotpatching: A new feature that allows Windows Server 2022 Datacenter: Azure Edition to apply updates without rebooting the system, improving uptime and reducing downtime in mission-critical environments.
• Improved Failover Clustering: Failover clustering now includes better integration with the Azure cloud, offering more resilient and fault-tolerant environments for hosting applications and VMs.

6. Enhanced Networking Performance

• UDP and TCP Performance Improvements: Windows Server 2022 includes enhancements to the User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) stacks, resulting in better performance for real-time applications and improved throughput in high-speed networks.
• QUIC Support: Built-in support for QUIC, a modern transport protocol developed by Google, enhances performance for applications requiring faster, secure, and reliable network communications.
• RDMA and SMB over QUIC: Remote Direct Memory Access (RDMA) allows for faster data transfers, and the introduction of SMB over QUIC improves secure file transfers without needing a VPN, providing seamless access to files across distributed environments.

7. Container and Application Modernization

• Windows Containers and Kubernetes: With Windows Server 2022, containers have improved compatibility, making it easier to deploy and manage containerized applications. It also supports Kubernetes clusters for enterprises adopting modern DevOps practices.
• Containerized Application Support: Enhancements in the Windows Container ecosystem make it easier to run legacy applications inside containers, improving portability and scalability. The containers also feature smaller image sizes and faster startup times.
• Windows Admin Center Integration: Windows Admin Center includes tools for managing containers, simplifying the deployment, monitoring, and maintenance of containerized applications.

8. Storage Enhancements

• Storage Migration Service (SMS) Improvements: With Windows Server 2022, the Storage Migration Service allows administrators to migrate not only files but also complete user accounts, configurations, and system settings from legacy servers, making it easy to modernize older environments.
• Nested Resiliency: Storage Spaces Direct (S2D) benefits from nested resiliency, which provides better protection for environments running with two-node clusters, ensuring high availability in edge scenarios or small deployments.

9. Windows Admin Center (WAC)

• Unified Management Interface: The Windows Admin Center has been enhanced to offer more powerful tools for managing servers, clusters, hyper-converged infrastructures, and Azure services, all from a unified web-based interface.
• Improved Security Management: Admins can leverage WAC to configure security settings, monitor performance, manage VMs, and integrate with Azure seamlessly.

   
Suitable Use Cases:
  

• Large Enterprises and Data Centers: Perfect for businesses needing scalable, secure, and high-performing server infrastructure capable of supporting complex workloads, hybrid cloud setups, and demanding applications.
• Hybrid Cloud Integration: Organizations that are adopting or expanding their hybrid cloud strategies can take advantage of deep integration with Azure services, improving operational flexibility and disaster recovery.
• High Availability Systems: Ideal for businesses running mission-critical workloads requiring high uptime, fault tolerance, and clustering.
• Containerized Applications and DevOps: Enterprises embracing modern DevOps practices can benefit from the improved container support and Kubernetes capabilities.

    
System Requirements:
   

• Processor: 1.4 GHz 64-bit processor (quad-core recommended)
• RAM: 512 MB minimum (2 GB for Server with Desktop Experience)
• Storage: Minimum 32 GB (more recommended based on workloads and roles)
