In the past Mac OS X was divided in the normal version and the Server version, now however Apple has decided that Mac OS X Lion will have a server version that for the very first time, it’s actually integrated into the normal operating system. This just goes to show how Apple’s really wants to deploy the entire package, and not ship several versions of their operating system.
Below is some information about the server update.
Lion Server is now part of Mac OS X Lion. It’s easy to set up your Mac as a server and take advantage of the many services Lion Server has to offer. Here are just a few of the new features that make server deployment faster, easier, and more powerful than ever.
Lion Server guides you through configuring your Mac as a server. And it provides local and remote administration — for users and groups, push notifications, file sharing, calendaring, mail, contacts, chat, Time Machine, VPN, web, and wiki services — all in one place.
File Sharing for iPad
Lion Server delivers wireless file sharing for iPad. Enabling WebDAV in Lion Server gives iPad users the ability to access, copy, and share documents on the server from applications such as Keynote, Numbers, and Pages.
