iOS:MDM和空中配置文件传递和配置之间的区别

我正在寻找iOS Universe上设备管理的解决方案，并且发现了两种方法:移动设备管理( http://developer.apple.com /library/ios/#documentation/NetworkingInternet/Conceptual/iPhoneOTAConfiguration/Introduction/Introduction.html ). 但是，我似乎找不到这两种方法之间的区别，或者在实践中两者是否相同. 有人可以澄清这个话题吗?

I'm looking for solutions for device management on iOS universe and I've found two approaches: Mobile Device Management (http://www.apple.com/ipad/business/it-center/deployment-mdm.html) and Over-the-Air Profile Delivery and Configuration (http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/iPhoneOTAConfiguration/Introduction/Introduction.html). However, I can't seem to find a difference between both approaches or if, in practice, both are the same. Can someone clarify this topic?
