Windows Server 2022 可用，它带来了高级多层安全性、与 Azure 的混合功能以及灵活^(Azure)的应用程序平台。它具有内置的安全核心功能，可帮助保护硬件、固件和Windows Server OS功能免受高级安全威胁。安全核心服务器基于Windows Defender System Guard和基于虚拟化的安全^(Security)性等技术，以降低固件漏洞和高级恶意软件带来的风险。

通过更快、更安全的加密HTTPS^(HTTPS)连接、行业标准的SMB AES 256加密等，连接也比以前更安全。

与早期的Server版本相比，Windows Server 2022还通过显着改进的 VM 管理改进了混合服务器管理，这是一个增强的事件查看器，在Windows Admin Center中提供了更多功能。对Windows容器进行了改进，例如更小的图像大小以加快下载速度、简化的网络策略实施以及用于 .NET 应用程序的容器化工具。

Windows Server 2022 版本^(Editions)比较

Windows Server 2022共有三个版本：

1. 标准
2. 数据中心
3. 数据中心：Azure 版

Microsoft详细介绍了每个版本中的功能。

1] Windows Server 2022 标准版^{(Standard Edition)}

Windows Server 2022 标准版^{(Standard Edition)}是三者中的主要版本。尽管塞满了所有通用功能，但它缺少 Hotpatching 和 Software-defined Networking^{( Hotpatching and Software-defined Networking)}。

存储副本^{(Storage Replica)}选项可用（1 个合作伙伴和 1 个具有单个 2TB 卷的资源组），但是它错过了存储空间直通^{(Storage Spaces Direct )}功能。它为两个虚拟机^{(two virtual machines)}提供了一个选项，每个许可证^{(Hyper-V host per license)}加上一个Hyper-V 主机以及2 个^{(2 )}Virtual OSE/Hyper-V isolated Containers.

Host Guardian Hyper-V 支持^{(Host Guardian Hyper-V Support)}不适用于标准^(Standard)版。

2] Windows Server 2022 数据中心版^{(Datacenter Edition)}

Windows Server 2022的数据中心版^{(Datacenter Edition)}比标准版^{(Standard Edition)}高出一步。虽然Hotpatching在这里也不可用，但是它包括软件定义的网络^{( Software-defined Networking)}。数据中心版提供无限^{(unlimited Storage Replica)}的存储副本，还包括存储空间直通^{(Storage Spaces Direct )}功能。继承激活可以作为主机或来宾完成。

比标准版^{(Standard Edition)}高出一步，数据中心版^{(Datacenter Edition)}提供无限的虚拟机，^{(Virtual machines)}每个许可证^{(Hyper-V host per license)}加上一个Hyper-V 主机以及无限^{(unlimited )}Virtual OSE/Hyper-V isolated Containers.

标准^(Standard)版中缺少Host Guardian Hyper-V 支持^{(Host Guardian Hyper-V Support)}，可用于数据中心版^{(Datacenter Edition)}。此外，还支持标准版^{(Standard Edition)}中不提供的受防护的虚拟机^{(Shielded Virtual Machines)}。

3] Windows Server 2022 数据中心^(Datacenter)：Azure 版

Windows Server 2022 数据中心：Azure 版^{(Windows Server 2022 Datacenter: Azure Edition)}是这3 者中最高级的，顾名思义，Azure支持（Azure IaaS或Azure Stack HCI – 21H2），并提供这些环境之外不可用的特定功能（热补丁^{(Hotpatching)}、基于QUIC的SMB和Azure 扩展网络^{(Azure Extended Networking)}）。Hotpatching尤其是这里的一个很棒的功能，它让管理员可以在不重新启动的情况下应用补丁，并且SMB over QUIC可以通过互联网安全访问共享文件，而无需设置VPN的麻烦。

管理中心^{(Admin Center)}包括Azure 混合中心^{(Azure Hybrid Center)}、Azure Kubernetes 服务^(Services)、Azure 备份^{(Azure Backup)}、Azure 文件同步^{(Azure File Sync)}、Azure Monitor和Azure 安全中心^{(Azure Security Center)}的菜单。

谈到其他功能，它是三者中最高级的，它包括标准^(Standard)版和数据中心^(Datacenter)版附带的所有其他功能。

Windows 2022有哪些安装选项？

Windows Server 2022产品附带适用于所有版本的核心^(Core)和桌面^(Desktop)安装选项。核心是无头低占用空间安装选项，建议用于远程管理和自动化目的。在桌面^(Desktop)安装选项中，它使用图形用户界面安装服务器，这是传统使用的方法，但不建议用于执行大规模自动化的组织。

Windows Server 2022 Editions compared and discussed

The Windows Server 2022 is available and it brings along advanced multi-layer security, hybrid capabilities with Azure, and a flexible application platform. It has inbuilt secured-core capabilities to help protect hardware, firmware, and Windows Server OS capabilities against advanced security threats. Secured-core servers are based on technologies such as Windows Defender System Guard and Virtualization-based Security to reduce risk from firmware vulnerabilities and advanced malware.

The connectivity is also more secured than before with faster and more secured encrypted HTTPS connections, industry-standard SMB AES 256 encryption among several others.

Compared to the earlier Server editions, Windows Server 2022 also improves hybrid server management with significantly improved VM management, an enhanced event viewer with more features available in Windows Admin Center. There are improvements to Windows containers, such as smaller image sizes for faster download, simplified network policy implementation, and containerization tools for .NET applications.

Windows Server 2022 Editions compared

There are three editions of Windows Server 2022:

1. Standard
2. Datacenter
3. Datacenter: Azure Edition

Microsoft has detailed the features in each of these editions.

1] Windows Server 2022 Standard Edition

The Windows Server 2022 Standard Edition is the primary version among the three. Although stuffed with all general features it misses Hotpatching and Software-defined Networking.

The Storage Replica option is available (1 partnership and 1 resource group with a single 2TB volume), however, it misses out on Storage Spaces Direct feature. It offers an option for two virtual machines, plus one Hyper-V host per license along with 2 Virtual OSE/Hyper-V isolated Containers.

Host Guardian Hyper-V Support is not available for the Standard version.

2] Windows Server 2022 Datacenter Edition

The Datacenter Edition of Windows Server 2022 is a step above the Standard Edition. Although Hotpatching is not available here as well, however, it includes Software-defined Networking. The Datacenter edition offers unlimited Storage Replica and includes the Storage Spaces Direct feature as well. Inherited activation can be done as a host or a guest.

A step above the Standard Edition, Datacenter Edition offers unlimited Virtual machines, plus one Hyper-V host per license along with unlimited Virtual OSE/Hyper-V isolated Containers.

Missing in Standard, Host Guardian Hyper-V Support is available for Datacenter Edition. Also, there is support for Shielded Virtual Machines which is not available in Standard Edition.

3] Windows Server 2022 Datacenter: Azure Edition

The Windows Server 2022 Datacenter: Azure Edition is the most premium among the 3 and as the name says is supported on Azure (Azure IaaS or Azure Stack HCI – 21H2) and offers specific features not available outside of these environments (Hotpatching, SMB over QUIC, and Azure Extended Networking). Hotpatching particularly is a great feature here, which lets admins apply patches without rebooting, and SMB over QUIC, for secure access to shared files over the internet without the hassles of setting up a VPN.

The Admin Center includes a menu for Azure Hybrid Center, Azure Kubernetes Services, Azure Backup, Azure File Sync, Azure Monitor, and Azure Security Center.

Talking about the other features, and being the most premium among the three, it includes all the other features that the Standard and Datacenter version comes with.
