System Center Virtual Machine Manager (VMM) is a tool for managing a virtualized datacenter, while App Controller offers a user-friendly interface for managing applications in various cloud environments, including VMM.
The question appears to be incomplete, but it seems to be asking about the relationship or comparison between System Center Virtual Machine Manager (VMM) and App Controller. These are both components of Microsoft's cloud and datacenter management solutions. System Center Virtual Machine Manager is a management tool for the virtualized datacenter. It allows administrators to deploy, manage, and configure a large number of virtual machines and services across multiple hosts and cloud environments.
App Controller provides a simplified interface that allows users to manage virtual machines, services, and private clouds hosted in VMM, as well as public clouds like Azure. In essence, while VMM provides a comprehensive management suite for virtual infrastructures, App Controller offers a user-friendly interface for managing applications deployed across various cloud environments, including those managed by VMM.
