Windows Admin Center (code named Project Honolulu) was unveiled by Microsoft on September 14th, 2017 as the necessary evolution of the Windows Server graphical user interface (GUI). Officially launched in public preview under the code name Project Honolulu at the Microsoft Ignite 2017 conference in Orlando, Florida, Windows Admin Center offers "flexible, locally-deployed, browser-based management platform and tools". The idea behind this project is to help simplify management of servers by placing a majority of the frequently referenced tools used by system administrators in one spot.  On April 12th, 2018 the project left preview and was named Windows Admin Center.
A list of features that are offered from this web based administration tool are as follows, and expected to grow with the ability for plugins and 3rd party extensions:
- Local Users & Groups
- Remote Desktop
- Roles & Features
- Storage Replica
- Virtual Machines
- Virtual Switches
- Windows Updates
There are a few like Storage Replica which don't have any alternative GUI so far.
In addition, Windows Admin Center also offers Hyper Converged Cluster Management.
At present, Microsoft only supports Microsoft Edge and Google Chrome browsers. Internet Explorer is not supported.
This tool is meant to manage Microsoft Windows Server platforms 2012, 2012R2, 2016, and 2016 version 1709. Windows Admin Center also supports managing Windows 10 client (local or remote) with fewer tools. In order for it to be able to manage Windows Server 2012/2012R2, there is a prerequisite to install the Microsoft Windows Management Framework (WMF) version 5 or higher to take advantage of the PowerShell features not included with those versions of the operating system. Through the web based Windows Admin Center interface you are able to add servers to be managed, although there is not currently a discovery option available for organizations with large server footprints.
When it comes to installing Windows Admin Center, it can be installed on a Windows 10, Windows Server 2016, or Windows Server 2016 version 1709 operating system. Installing Windows Admin Center requires a ~30MB Microsoft Installer Package (MSI). Walking through the installation it will ask for a port to serve the website on, as well as the ability to generate a self-signed SSL cert or use an SSL cert from your Certificate Authority, for example. In terms of configuration options that is all that is required to install. Upon completion, access Windows Admin Center over the web you will need to add servers in order to manage them. 
Windows Admin Center was brought into existence because "IT admins have repeatedly told us that PowerShell is necessary but not sufficient, and that Windows Server ease-of-use is still largely dependent on GUI Tools for core scenarios and new capabilities" Windows Admin Center builds off of the Microsoft Management Console (MMC) that was first introduced in Windows 2000. It takes some of the most commonly accessed management utilities, such as the Event Viewer, Roles and Features, Hyper-V management, Windows Firewall, and the Registry editor and combines them into a centrally accessible, web based friendly, intuitive interface that makes accessing these items simplified and straightforward.
