Microsoft announced their new release of Windows Server 2022. Windows Server 2022 comes with many new features and improvements compared to the previous releases. This blog post will go through the best new features you can get with Windows Server 2022. 

Windows Server 2022 is the most secure, reliable and Azure-compatible operating system that Microsoft developed. With the recent data breaches that cost millions of dollars, Microsoft developed Windows Server 2022 with top-notch security parameters to combat the increasing security threats. 

Windows Server 2022 comes with three main editions: 

  1. Windows Server 2022 Essential 
  2. Windows Server 2022 Standard
  3. Windows Server 2022 Data Center

These three versions have their differences which will be covered shortly. However, all three versions are able to install the server core and desktop versions. The desktop version is installed between non-server services and other components for remote desktop sessions. 

Windows Server 2022 Essential 

  • This is designed for small organizations that support a maximum of 25 users and for 50 devices.
  • This version does not come with the following features: dashboard, client backup and access anywhere.
  • It can support processors with up to 10 cores. 

Windows Server 2022 Standard

  • This is the base version of Windows Server 2022. 
  • A single license will work with two virtual machines and one Hyper-V host.
  • You will have the replica storage option with one partnership. 
  • The hot patching and software-defined networking and storage features will not be available with the Standard version. 

Windows Server 2022 Data Center

  • This feature comes with the protected VM feature. This is a security measure to protect the firmware and startup files of the virtual machine. 
  • Using Storage Spaces Direct, you will be able to use the software-defined storage and storage replication features. 
  • Supports up to 16 servers and up to 1 petabyte of cluster storage. 

In this section, we will discuss the minimum hardware requirements that you will need to run the operating system at a satisfactory level. If you do not meet the required factors, most likely, the installation will not be completed: 

  • Processor: 1.4 GHz 64-bit processor, 64-bit compatible
  • RAM (Storage): 512 MB and 2 GB for server with the option to install Desktop Experience.
  • Network: NIC card with a minimum bandwidth of 1 GBPS
  • HDD: 32GB

Windows Server 2022 has a higher focus on security and comes with advanced multi-layer security and hybrid capabilities with Azure. The new features are focused on helping protect hardware, firmware and OS capabilities from advanced security threats. 

Let’s get started with the new features!

1.   Storage Improvements

One of the major improvements can be found here in the Server 2022 version. Advanced data storage upgrades are built into the 2022 servers:

  • Advanced caching automatically stores important data on faster storage volumes while keeping the less critical ones on slower volumes. 
  • Storage improvement, which fixes the hard drives faster in case of server restart or hardware failure. 
  • ReFS snapshot feature takes snapshots of data at constant times, regardless of size. 

2.   Updated Security measures 

The most notable improvements ensure that the server is self-reliant to process sensitive data and critical applications. The entire server core is protected from the perspective of hardware, firmware, and drivers to prevent cyber attacks. The security protocols and enhancements are: 

  • DNS support with DNS-over-HTTPS
  • Server Message Block AES-256 and SMB East-West encryption
  • SMB over QUIC
  • HTTPS and TLS 1.3
  • Azure Arc
  •  Azure Automanage

Windows Server 2022 also comes equipped with DRTM (Dynamic Root of Trust for Measurement) and DMA (Direct Memory Access) to prevent firmware-related cyber attacks. 

Hypervisor security is also upgraded with virtualization-based security technology (VBS).VBS allows individual processes to be isolated from the operating system. With this technology in place, if an attack occurs, then the attack does not spread to other parts of the system. 

3.   Server hardware improvements

With the new Server 2022, the hardware limitations have been extended. Windows Server 2022 supports 48 TB of memory and 2048 logical cores running on 64 physical sockets. It also supports Intel's Ice Lake SGX processor, which helps in isolating sensitive data in an encrypted processor section during processing. 

4.   Improvements in Azure capacity

Microsoft Azure capabilities have been extended in Windows Server 2022 by introducing virtualization support outside the network and other vendors. Azure Arc-enabled servers offer a comprehensive and secure approach to integration anywhere in on-premises, multi-cloud, and edge environments.

5.   Improvements in networking

The two major networks used in Networking are TCP (Transmission Control Protocol) and UDP (User Datagram Protocol), which have been significantly improved with the new Windows Server version. 

For UDP: In all Windows 2022 servers, UDP Segmentation Offload (USO) and UDP Receive Side Coalescing (UDP RSC) are included, which helps in reducing the CPU load times. 

For TCP: To reduce the packet loss during connection startup, Windows Server 2022 comes equipped with TCP HyStart++ and RACK to shorten retransmission times. 

QUIC: This feature appeals to IT professionals because it makes it easy to copy files remotely without the need for a VPN over an advanced SMB (Message Block Server).

Like new features are added to the newer versions, Microsoft removes some old functionalities. 

  • Semi-Annual Channel (SAC) - The SAC channel will be replaced with a long-term channel as the primary release channel. 
  • Internet Storage Name Service (iSNS) Server.
  • Guarded Fabric and Shielded Virtual Machines will be supported, but no further development will occur. 
  • Remote Server Administration Tool (RSAT) will be removed from the client version of Windows. 
  • Windows Deployment Services (WDS) are partly denounced. 

With the adoption of Microsoft Windows Server 2022, enterprises can manage their businesses with a secure infrastructure, integrate their existing virtual environments into their hybrid cloud models, and restructure their applications to meet demanding growth.

There are a lot of new features, and with Windows 2022 Servers, you can expect increased security measures in place. The new release also provides secured connectivity that introduces several new capabilities, such as faster and more secure encrypted HTTPS connections.
