Mapping Technical Services to Application Services

We are getting ready to map our Application Services to our Technical and Business Service Offerings, using the Application Service Wizard. One thing that has been confusing, is when using the application service wizard are we mapping Technical Services offerings that underpin / help deliver the Application Service, or are we selecting Technical Service Offerings that the application Service delivers?

I believe the answer is the first one, for example we have a TSO For "Cloud Services Management", which could be mapped to the application service when the application utilizes cloud infrastructure, but I wanted to confirm as I keep seeing conflicting responses. If this is the case, how do we map technical service offerings that the application service delivers?

Thank you for any guidance!
