Apple has quietly posted an overview guide to Mountain Lion Server. The 25 page PDF document is available from Apple’s OS X Server Resources page, which barely references Mountain Lion at all. The generically named OS X Server Product Overview link in the page’s Documentation section, however, links to the new Mountain Lion Server product brief.

The overview guide is listed as being updated for June. That implies that it was deliberately placed there in advance of next month’s Mountain Lion release (as opposed to going live early by mistake). The guide primarily focuses on introducing the various features in Mountain Lion Server. While not in-depth, it definitely provides a sense of where Apple is going with Mountain Lion Server as well as with Mac and iOS management.

OS X Server has always been something of a bargain compared to the various flavors of Windows Server. Unlike Microsoft, Apple never focused on a client access licensing model in which organizations must pay for the server software itself plus additional licenses for users or devices that connect to it. Apple also doesn’t break OS X Server down into multiple variations each with its own features, licensing needs, and upgrade limitations.

When you buy OS X Server, Apple gives you everything from file sharing to Internet and collaborative services like wikis and internal messaging through Mac and iOS device management. If you start as a small business with a single basic server and eventually grow to the point where you need to support and manage dozens or hundreds of Macs, PCs, and mobile devices, there are no limits imposed on licensing or data migration.

WWDC is only a few days away and the event is shaping up to be filled dramatic announcements. Expectations include an Apple HDTV, a new Mac lineup that includes an updated Mac Pro, the unveiling of the next iPhone, iOS 6 with Siri support for the iPad, updates to Siri’s functionality, and load of additional details about Mountain Lion.

Whether all those expectations are met or not, WWDC and its keynote will pack lots of information for developers and IT professionals as well as various Apple product announcements and previews. The big announcements may be the best part of WWDC for most Mac users and Apple fans, but the event is, at its heart, a giant powwow for developers. It also offers IT professionals and CIOs their best glimpse at Apple future plans and the new technologies that they will need to support and/or manage.

So what are IT leaders and business professionals going to be looking for at WWDC? Here’s our IT wish list for this year’s WWDC.

Apple followed up yesterday’s Mountain Lion Developer Preview update with a new seed of Mountain Lion Server. Unlike some Mount Lion preview updates, which showed up in Software Update on Macs running the previous developer previews, Apple made this update visible in the Apple Developer Center website.
