App Controller is a super-set of the functionality in the self-service portal. With App Controller you can:

• View and deploy virtual machines and services (the self-service portal shows only virtual machines)
• View virtual machines and services from more than 1 VMM management server (providing they are in the same trust boundary)
• Upgrade services
• Copy files to/from VMM libraries
• View, deploy and upgrade services running in Windows Azure
• Use Active Directory users and groups to provide access to Windows Azure subscriptions
