“…Creating a stateful data drive is infeasible because the original data inside the drive is lost forever and cannot be replicated, even though the empty drive can be created by calling the relevant cloud API function. Reassigning a new IP address to a cloud instance is not feasible because this activity by cloud consumers is not allowed by public cloud platforms because of the limited visibility and indirect control of cloud . Hence, as long as the state transition does not involve data drive creation or IP address reassignment, it is feasible.…”

“…Conventional telecom service definition and design, each service is independent with specific data model, provision process and system interface; such design concept is called silo architecture [9]. Due to the reason, information is hard to be shared between systems and several stand-along service enabling processes cannot be linked smoothly for service integration.…”
