Abstract:
Data center industry uses a number of metrics to assess efficiency and energy consumption of cloud computing systems focusing mainly on the efficiency of IT equipment, cooling and power distribution systems. Unfortunately, most of the available metrics are too generic and do not differentiate at a finer grade between individual IT subsystems. For example, existing metrics, such as the widely used Power Usage Effectiveness (PUE), do not allow distinguishing the efficiency of the data center communication system from the efficiency of the computing servers, as both remain considered under the common umbrella of the IT equipment.
This talk will introduce a framework of new metrics capable of assessing performance and energy efficiency of cloud computing communication systems, processes and protocols. The proposed framework is positioned to become an essential tool for academy researchers and industry specialists in the field of communication systems and cloud computing data centers. This framework is currently proposed for standardization and has become an enabler for a new type of resource allocation and scheduling solutions, which optimize the tradeoff between job consolidation and distribution of traffic patterns, and emphasize the role of communication fabric for energy efficient job placement and load balancing.
