FairWatt: An Energy Accounting System for Fair and Sustainable Data Centers

The energy demand from data centers is expected to double in the next couple of years. With this in mind, increasing the energy awareness of data centers' customers and providers is a key step towards realizing potential actions to slow down the energy demand. However, creating energy awareness is not an easy task, as data centers are primarily multitenancy environments where participants share physical and digital resources. We propose an energy accounting system for data centers called FairWatt that aims at allocating energy in a fair way and increasing the energy awareness of stakeholders. Fairness is integrated at design time by means of fairness policies and scenarios, and assessed at runtime through the novel Shared B2 fairness score and Fairness Rulings.
