Windows Admin Center is a new, locally-deployed, browser-based management tool set that lets you manage your Windows Servers with no Azure or cloud dependency. Windows Admin Center gives you full control over all aspects of your server infrastructure and is particularly useful for managing servers on private networks that are not connected to the Internet.
Windows Admin Center is the modern evolution of “in-box” management tools, like Server Manager and MMC. It complements System Center and Operations Management Suite – it’s not a replacement.
