Edge Cloud Gateway Service for an App

We are presenting a basic two edge two gateway two server per cluster configuration to migrate an application app1 for subscriber s1 as he/she moves with his User Equipment using application served from edge closest to it as managed by central cloud. All elements of standard mobile subscriber provisioning are assumed except that the application is now served from edge. The notion of state of application can be either with device or network and for now we can assume moving stateless application to simplify first implementation.
