Software Update is a service likely best suited for environments with at least five Mac OS X computers who are looking to centrally manage the software patches from Apple. These updates are cached on the Mac OS X Server and then deployed as needed to client systems that subscribe to the Software Update service installed on the server. This reduces the amount of bandwidth required on the server and allows administrators to release software in batches, thus keeping support costs at a minimum (assuming of course that most support incidents derive from change introduced in the environment).
The initial installation of Lion Server’s Software Update service is one of the easier services to set up and manage.
