From the Origins of Performance Evaluation to New Green ICT Performance Engineering

Part 2: Trends: Green ICT and Virtual MachinesInternational audienceThis paper intends to present an overview of the evolution of performance evaluation since its first steps the Erlang works for modelling telephone networks, based on simple queues until the present current challenges in Green ICT that will require the development of new paradigms and mathematical tools, and rapidly passing across the modelling works of Khintchine and Pollaczeck; Jackson; Baskett, Chandy, Muntz and Palacios; Buzen; Reiser and Lavenberg; and many others, and benchmarking standards that have produced solutions to the problems appearing in these hundred of years. Finally, we analyze some of the challenges of computer performance evaluation appearing today, mainly those related to the energy consumption and sustainability, globally known as Green ICT
