Include an Architecture preview for Virtual Machines, Databases, Virtual Networks and their Subnets, NSG's, load balancer, app services and any other services which connected in some or other manner.
1) To let know the user their connectivity and structure and to know whether they are connected as expected or not.
2) Help them use the resources effectively.
3) Chances are where they may upgrade to newer resources available or delete unnecessary resources which have been running. That is cost effective.
Even we can have a “live preview” or “mapping” service, which didn't meet the expectations. Hope Azure Team will update those services.
