Let me break it down for you...
Apple Configurator and DEP accomplish a few of the same things. However it is the way in which they accomplish them, and the circumstances of your deployment which will determine if you will use one or the other. Or even both. I want us to try to get away from the notion of Apple Configurator vs DEP.
Let's start with Apple Configurator (The older brother of DEP).
Apple Configurator came around to accomplish a couple of key things...
- Supervise iOS Devices (If you do not know what this means, read my article on device supervision here)
- Create and Install Configuration Profiles (These are little lists of settings that the iOS device must obey)
- Install Apps without the need for Apple ID (This process has changed significantly between AC 1 and AC 2)
- Enroll iOS devices into a 3rd party MDM Software.
Here is the caviat. Since Apple Configurator is a Mac App Store App (free by the way), all modifications to devices, such as changing profiles, installing apps, enrolling in MDMs, wiping, etc.. Devices must be plugged into the Mac running Configurator via Lightning/30 Pin cable. This is not the worst thing ever considering the fact that Apple Configurator can push this information (by wire of course) to 30 devices at a time. So if you have yourself a USB hub, or a Bretford PowerSync cart, you should be able to breeze through this.
