System Center App Controller

The App Controller provides a self-service experience through a web portal that can help you easily configure, deploy, and manage VMs and services across private, third-party hosters (that support Microsoft Hyper-V) and public clouds (Azure). For example, moving a VM from a private cloud to Azure, creating checkpoints, granting access, scaling out deployed services, and so on.

The App Controller has been used as a replacement of the VMM self-service portal since SC 2012 SP1. It was deprecated in the SC 2012 R2 time and finally removed in SC 2016. As noted above, you should plan Azure Pack deployment instead of current App Controller instance.
