Admin Center: installation in gateway mode

Intro

In this tutorial, we will see how to install the Admin Center in gateway mode.

As a reminder, the Admin Center is a Web interface that allows the administration of Windows servers using WinRM.

From the Admin Center, it is almost possible the same as with the graphical interface:

  • Monitor a set of servers
  • Install roles
  • Change network configuration

The Admin Center offers a graphical interface for the administration of a hyperconverged infrastructure.

Installation in Gateway mode, requires a dedicated Windows 2016/2019 server for the Admin Center

Unlike the local mode, that is to say that the Admin Center is directly installed on your Windows 10 computer (tutorial on Windows 10), the gateway mode will allow you to dedicate a server to the Admin Center which will be accessible by a Internet browser from any compatible Internet browser. This amounts to dedicating a server to management.

Below, an infographic from the Microsoft site that allows you to view the different types of deployment possible.

During installation, no configuration is necessary, installation in Gateway mode is automatic from the moment the Admin Center is installed on a Windows 2016/2019 server.

Prerequisites

A Windows 2016 or 2019 server preferably dedicated to the Admin Center and joined to the Active Directory domain.

If you want to install the Admin Center on a non-dedicated server, this must not be a domain controller and must not have the IIS role installed.
