Following this morning’s launch of 10.8 Mountain Lion on the Mac App Store, Apple just launched a separate app as an OS X Server for Mountain Lion. It allows users to add sever functionality to the OS for $20. It is definitely a significant price drop from the $49 Lion server and the $500 or so it cost to add the functionality before that.

OS X Server is the next generation of Apple’s award winning server software. Designed for OS X and iOS devices, OS X Server makes it easy to share files, schedule meetings, synchronize contacts, host your own website, publish wikis, configure Macs, iPhones and iPads, remotely access your network, and more.

Server is now an application you can add to Mountain Lion right from the Mac App Store. Anyone can quickly and easily turn a Mac running Mountain Lion into a server that’s perfect for home offices, businesses, schools, and hobbyists alike.
