Abstract:

Computing centres are becoming increasingly large, with digital services hosted all over the world and often belonging to complex systems, themselves using many other services and hardware resources. This increase is accompanied by an alarming growth in digital infrastructure and its energy consumption. Despite the complexity of these systems, it is important to understand how they consume energy in order to chase wasted joules. This talk will discuss measuring the energy consumption of Cloud infrastructures, deriving models from these measurements and implementing these models in simulation tools that can be used to assess their energy consumption and estimate their environmental impact.
