Microsoft has been making client operating systems since 1985, when Windows 1.01 was first launched.
However, the first server was not released till 1993 after the introduction of New Technology (NT).
Windows Servers are used for enterprise-level management, data storage, applications, and communications.

Using this group of operating systems, administrators can apply and implement policies while enhancing their networks security infrastructure.

The version for Servers is what evolved into the Server family which continues to date.

Microsoft then skipped directly to version 3.5.
This was a major feature for the sustainability of NT Servers since they were relatively new to the market.
This included theInternet Information Server (IIS)which was in direct competition with Apache HTTP Server.
Furthermore, Microsoft also added the Transaction Server and the Message Queue Server to improve the OS.
For example, Windows Server 2000 was released in the year 2000.
This version mostly focused on enhancing the security of the OS as well as the web link.
It introduced Active Directory Federation Services (ADFS) for user authentication.
It also included Remote Desktop Services for the very first time on a Server OS.
Windows Server 2012
Windows Server 2012 included better features for off-site server integration.
This was mainly done by Microsoft so it can be integrated with cloud servers and services.
Furthermore, they also updated the storage system with this OS, which was mediated by Hyper-V itself.
Not only that, but the Hyper-V virtual switch and Hyper-V Replica were also introduced in Server 2012.
It also included updates to Windows PowerShell.
Virtualization and storage technologies were also overhauled and the Web services were enhanced.
An encryption system was also added for Hyper-V to secure the VMs.
Another milestone for Microsoft was the support forcontainers.
Server 2016 also included the web connection Controller.
This enabled administrators to manage both physical as well as virtual web link devices using a single console.
However, this feature is only available in theDatacenter edition.
This facility aims to obtain all the functions of a miniature data center without the additional hardware costs.
