A Survey on Metrics and Measurement Tools for Sustainable Distributed Cloud Networks

Energy efficiency and emissions awareness are core capabilities for sustainable and lower cost distributed cloud networks. In this context, metrics are fundamental for comparison and management purposes, along with the methods and tools which support such metrics' capture and analysis. However, prior works on green metrics and tools have presented only a partial view, mainly as a result of the recent advances in green networking technologies. In this survey, we present an extensive study of metrics, methods, and tools to support sustainable operations in distributed cloud networks, with the aim of providing an end-to-end and up-to-date scenario to support current and coming research, as well as to analyze existing gaps.
