Windows Server Update Services (WSUS)
The WSUS server that acts as an update source is called an upstream server.
In a WSUS implementation, at least one WSUS server in the network must connect to Microsoft Update to get available update information.
The core scenarios where WSUS adds value to your business are:
Centralized update management
Update management automation
Windows Server Update Services is a built-in server role that includes the following enhancements:
Can be added and removed by using the Server Manager
Includes Windows PowerShell cmdlets to manage the most important administrative tasks in WSUS
Adds SHA256 hash capability for additional security
Provides client and server separation: versions of the Windows Update Agent (WUA) can ship independently of WSUS
