I have a customer with a fleet of iOS devices. They deployed them over time without any central management / MDM solution. iOS versions range from 6 to 8.
They assigned each device a unique Apple ID during registration.
They would like to push-install or distribute, in some way, applications and web shortcuts to all iOS devices.
I realize that without some kind of MDM that integrates tightly with iOS, this can't happen. What are some good options in this scenarios. Unlike Android, iOS won't allow installation of apps from unknown sources, so it's not as simple of pushing an .apk from an MDM solution.
I've researched some of the solutions such as Apple's Volume Purchase Program (VPP), etc. but enterprise management of iOS devices seems a bit oqaque. Any guidance would be greatly appreciated.
