Windows Server 2022 is the cloud-ready operating system. It delivers new layers of security and Azure-inspired innovation for the applications and infrastructure that power your business.
Windows Server 2022 helps accelerate time to value by simplifying your underlying infrastructure. Moreover, it allows you to reduce cost by taking advantage of industry-standard hardware.
At the heart of the Microsoft Cloud Platform, Server brings Microsoft’s experience delivering global-scale cloud services into your infrastructure.
Windows Server 2022 builds on Windows Server 2019, our fastest adopted Windows Server ever. This release includes advanced multi-layer security, hybrid capabilities with Azure, and a flexible platform to modernize applications with containers.
Windows Server 2022 preview is a long-term servicing channel (LTSC) product version. You can download it by Windows Insider Program, or you can test it on Azure virtual machine infrastructure via an Azure Portal download from the Azure Marketplace. The latter option delivers Azure Security Baseline settings that are configured by default.
Windows Server 2022 Features:
Advanced multi-layer security
With a growing number of cyber-security threats and the impact of incidents escalating quickly, security is a top priority for our customers. Windows Server 2022 includes new security capabilities like secured-core server and secure connectivity.
Secured-core server brings powerful threat protection together to provide multi-layer security across hardware, firmware, and the operating system. It uses the Trusted Platform Module 2.0 and System Guard to boot up Windows Server securely and minimize risk from firmware vulnerabilities. Secured-core server also includes virtualization-based security (VBS) features like Credential Guard and Hypervisor-protected code integrity (HVCI). Credential Guard provides preventative defense for sensitive assets like credentials, and HVCI applies hardware – rooted security to prevent advanced malware from tampering with the system.
Secured connectivity adds an additional layer of security during transport for advanced protection. Windows Server 2022 improves connection security with faster and more secure encrypted hypertext transfer protocol secure (HTTPS) and transport layer security (TLS) 1.3 enabled by default. Customers can also further secure server communications with industry-standard AES-256 encryption, which now supports server message block (SMB) protocol and better controls.
Hybrid capabilities with Microsoft Azure
The new capabilities enables customers to take advantage of cloud innovation with their on-premises investments. Azure Arc and Storage Migration Service are two key hybrid capabilities that work best with Windows Server 2022.
Azure Arc enables customers to manage, secure, and govern Windows Server on-premises, at the edge, or in multi-cloud environments from a single control plane in Azure. Through Azure Arc, customers can easily employ Azure management capabilities such as Azure Policy, Azure Monitor, and Azure Defender for those servers. What’s more, a few simple clicks in Windows Admin Center can enable connectivity to Azure Arc. Further, has been enhanced Windows Admin Center v2103 with significantly improved virtual machine management, a simpler event viewer, and many more updates. Windows Admin Center is also available in the Azure portal.
Windows Server 2022 enhances the seamless connectivity of file servers on-premises to file servers on Azure. Updates to Storage Migration Service allow customers to migrate file servers from NetApp FAS to Windows Servers. Using Storage Migration Service to migrate data to servers allows customers to maintain low latency while reducing their on-premises storage footprint.
Flexible application platform
Customers use Windows Server to run large-scale and distributed applications. Consequently, we have placed relentless focus on bringing platform capabilities and tools that improve developer velocity and support for business-critical workloads like SQL Server.
In this release, we are adding several platform improvements for Windows Containers, including application compatibility and the Windows Container experience with Kubernetes. A major improvement includes reducing the Windows Container image size, which leads to faster download time and better performance. In addition, you can now run applications that depend on Azure Active Directory with group Managed Services Accounts (gMSA) without domain joining the container host. Furthermore, there are several other enhancements that simplify the Windows Container experience with Kubernetes. These enhancements include support for host-process containers for node configuration, IPv6, and consistent network policy implementation with Calico.
In addition to platform improvements, updated Windows Admin Center tool makes it easy to containerize .NET applications. Once the application is in a container, you can host it on Azure Container Registry to then deploy it to other Azure services, including Azure Kubernetes Service.
Windows Server 2022 supports business-critical and large-scale applications like SQL Server that require 48 TB of memory and 2,048 logical cores running on 64 physical sockets.
