TL;DR: The usage of methods and technologies currently used for energy-efficient operation of computer hardware and network infrastructure and some of the remaining key research challenges that arise when such energy-saving techniques are extended for use in cloud computing environments are identified.

TL;DR: How cloud technologies and flexible functionality assignment in radio access networks enable network densification and centralized operation of the radio access network over heterogeneous backhaul networks is discussed.

TL;DR: The novel concept of RANaaS (Radio Access Network-as-a-Service) as a flexible architecture based on centralized processing, capable of handling the increasing interference in very dense networks, reducing energy consumption, cost-efficiently deploying and managing cellular networks is introduced.

TL;DR: A vision of the advantages of the RANaaS is given, its benefits in terms of energy efficiency are presented, and a consistent system-level power model is proposed as a reference for assessing innovative functionalities toward 5G systems.

TL;DR: The goals and work being done within the 5GEx (5G Exchange) project in realising a Europe‐wide multi‐domain platform aimed at enabling cross‐domain orchestration of services over multiple administrations or over multi‐ domain single administrations in the context of emerging 5G networking.
