I would like a process to export all the azure configurations and import them into Visio to be able to build accurate architecture diagrams of the environment. This would allow for a 'point in time' reference for what is the current state. Expanding on this would be the ability to have templates of diagrams to represent different perspectives of the environment ( network / server details / etc. ). Through the use of TAGS and Metadata, you could produce the layout of platforms / applications / business aligned systems / etc.
Producing these artifacts and versioning over time will show the evolution of an environment
Eventually this feature could be incorporated completely into the portal ( export, rendering of Visio, storage of artifacts) as a service offering. consumers of the service can upload desired templates. Documents can be scheduled to be produced on intervals, on demand, or only if changes were made that day.
