Ecological implications of Cloud-based IT infrastructures are creating a critical gap in the current state of the art in research and business. The ECO2Clouds project investigates strategies that can both ensure effective application deployment on the Cloud infrastructure and reduce energy consumption and CO2 emissions. The need for novel deployment strategies becomes more evident when an application spans multiple Clouds. Cloud providers operate under different regulatory frameworks and cost structures in relation to environmental policies and energy value-chains. In addition, optimising the way key assets such as machines, applications and databases are deployed is constrained by a set of requirements such as quality, privacy and cross-platform, service-level agreements.

ECO2Clouds will provide a challenging and innovative approach to Cloud computing service delivery by:

  • developing extensions and mechanisms for Cloud application programming interfaces to collect eco-metrics at the IT infrastructure and Virtual Machine levels, and quantify the environmental impact of execution at infrastructure and application level;
  • investigating the key environment, and the needed quality and cost parameters, so as to underpin a comprehensive approach to multi-cloud application deployment;
  • developing evaluation mechanisms and optimization algorithms to assess different parameter configurations and their influence in energy-efficient Cloud sourcing and application deployment strategies;

The carbon-aware mechanisms will be integrated into the FIRE facility BonFIRE so as to test, validate and optimize the eco-metrics, models and algorithms developed and improve the FIRE offering.

GAMES Project

The vision of the GAMES project is for a new generation of energy efficient IT Service Centres. With the unprecedented digitisation of business and government processes across Europe, energy efficiency of IT Systems and IT Service Centres is dramatically emerging as one of the most critical environmental challenges to be dealt with.
A first yet partial answer to the energy challenges is offered by the emerging IT Service Centre paradigm, in which the available computing resources are shared by several different users. However, current tools and methods for assessing and managing energy efficiency at the IT Service Centre level were designed to operate in isolation, not taking into account all the interrelations between the different layers (business/applications, infrastructure, facility) and the effect of these interrelations on energy consumption.
The GAMES project aims at developing a set of innovative methodologies and Open Source ICT tools for designing and managing energy efficiency in IT Service Centres, by combining all the three above layers. This will be done by: 1) delivering a methodology and a web toolset for the holistic design of green IT service centres, trading-off Quality of Service, performance, virtual and physical resource allocation and overall energy efficiency, 2) enriching the GAMES toolset by implementing advanced algorithms for closely aligning applications’ demands for power with the resource availability, and combining these algorithms with data mining technologies; 3) complementing these design tools and methodology in a run-time environment for integrated sensing, monitoring and adaptive control, capable of assessing in real time to a what extent the implemented course of actions will improve energy efficiency.
The main expected outcome will be to increase energy efficiency in IT Service Centres by up to 25%. The effectiveness of the proposed solutions will be validated through extensive real life partner testbeds located in Italy and Germany.

The role of Politecnico di Milano in the project will be mainly in the development of new methods and tools for designing energy-aware information systems, including optimization tools to be applied both at
design and at run time to optimize services and infrastructure parameters. Adaptivity within an active control loop involving both service, infrastructure and context information and control will be studied, designing new adaptation mechanisms based on context and interlayer feedbacks.

Il programma di ricerca, “SeNSoriSensor Node as a Service for Home and Buildings Energy Saving”, ha come oggetto la sotto-area A4, “Tecnologie e soluzioni impiantistiche per gli ambienti civili ed industriali”, sviluppando il tema progettuale, al punto 2, “sviluppo di sistemi di controllo totale dei flussi energetici, elettrici ed idrici negli ambienti sociali ed abitativi”.

L’obiettivo del programma è la definizione e realizzazione di una Piattaforma per l’ambient intelligence per il controllo totale dei flussi energetici, elettrici ed idrici, negli ambienti civili ed abitativi. Con tale programma si vuole innovare il “sistema casa” e quello “office”, settori fondamentali del Made in Italy, supportando una significativa innovazione di prodotto, grazie sia all’introduzione di conoscenze scientifiche e tecnologiche, che allo svolgimento di attività mirate all’acquisizione di nuove conoscenze.
