Windows Server is one of the server-oriented operating systems developed by Microsoft. It is a server license which allows the deployment of a client-server application architecture, a network infrastructure and connected web services. There are about ten versions, from Windows NT to the most recent version Windows Server 2022, released in August 2021. The editor has been able to evolve the technologies and features to offer user companies reliable and secure environments, in line with the new needs of agility, mobility and hybridization. The latest version is no exception to the rule and offers four editions (Windows Server 2022 Essentials, Standard, Datacenter and Datacenter Azure Edition) with numerous innovations in the key areas of security, integration and management of the Azure hybrid environment and the application platform. Windows Server 2022 is a long-term version and benefits from long-term support through the LTSC (Long Term Servicing Channel) program.
Windows Server 2022 Editions
The editions Windows Server 2022 are defined for different contexts. Thus, Windows Server 2022 Essentials is ideal for small businesses with up to 25 users and 50 connected devices. The Standard version is suitable for low-virtualized physical environments, and the Datacenter and Datacenter Azure Edition versions are for highly virtualized hybrid and cloud environments. The licensing model is dedicated server-based for the entry-level versions and core-based for the Standard and Datacenter versions.
The editions have many common server features, such as dynamic memory management, MMC management console, server interface, Network Load Balancing, Volume Activation Service, Windows PowerShell, Windows Server Update, and standard roles such as DHCP and DNS servers, file, storage and print services, web services (IIS). They differ with respect to certain limits such as the number of VMs allowed, roles such as the network controller of specific features, Azure WAN, only present in the version Windows Server 2022 Datacenter Azure Edition...
Embedded innovations in Windows Server 2022
Built on the foundation of Windows Server 2019, the Windows Server 2022 offers many innovations in security, application platform, integration and management of hybrid environments.
Safety innovation
The new security-related features combine security features deployed in the various domains of Windows Server 2022. The result is advanced multi-layered security, with the Secured-core server system, the use of a secure platform module (TPM 2.0), firmware protection and virtualization security. Multi-layer security also includes connection security, default use of HTTPS and TLS, name resolution, encrypted DNS, etc.
Innovation hybrid environment
Another new feature is the integration of Azure hybrid functionalities into Windows Server 2022 to increase system agility across large and hybrid environments. Versions with Azure Arc functionality provide powerful management of virtualized instances and facilitate the transfer of local Windows servers to Azure instances in the cloud. This version of Windows Server 2022 benefits from many other features such as Azure Automanage Hotpatch allowing hot updates to be performed on VMs.
Innovation application platform
As far as application platform innovations go, they lie in Windows Container instances, with the reduction of the size of the Windows Container image and the ability to launch applications managed under Azure Active Directory from group-managed service accounts without connecting to the connector host domain. Aside from these virtualization aspects, Windows Server 2022 also supports critical applications such as SQL Server.
Other innovations
Several other features have been implemented in this latest generation of Windows Server. These include nested virtualization for AMD processors, improved network performance of the User Datagram Protocol (UDP) and Transmission Control Protocol (TCP), the implementation of a storage migration service, and the acceleration of repair and synchronization routines after a node restart following a data storage problem.
Hardware requirements for Windows Server 2022
The configuration detailed in this chapter is standard, i.e. it does not take into account all possible deployment assumptions. When installing Windows Server 2022For each specific server role, you should check the requirements. It is advisable to carry out test phases to determine the ideal hardware configuration according to the system architecture you wish to implement.
The minimum system requirements are an Intel 1.4 GHz 64-bit processor, which must be compatible with the x64 instruction set and support second-level address translation and features such as NX and DEP (intelligent processor resource allocation). The RAM requirement is 512 MB of ECC (Error Correcting Code). For the creation of a virtual computer, 800 MB must be allocated for this VM. The disk space requirement is 32 GB with a compliant storage controller and PCI Express specifications. The server on which you install your Windows Server 2022 must be equipped with a network card that complies with the PCI Express architecture specifications and offer a minimum throughput of 1 gigabit/second.
You will find on the Softcorner marketplace the licenses Windows Server 2022 you need. These less expensive used versions, available for download, are complete. They include everything you need to install and deploy your Windows Server architecture. Don't wait any longer, buy your software licenses second hand or resell your licenses to participate in a green economy and circular.
