Cloud computing is expected to be a major factor that will dominate the future Internet service model. This talk summarizes our work on energy efficiency for cloud networks. We describe a framework for studying the energy efficiency of four cloud services in IP over WDM networks: cloud content delivery, storage as a service (StaaS), and virtual machines (VMS) placement for processing applications and infrastructure as a service (IaaS). Our approach is based on the co-optimization of both external network related factors such as whether to geographically centralize or distribute the clouds, the influence of users' demand distribution, content popularity, access frequency and renewable energy availability and internal capability factors such as the number of servers, switches and routers as well as the amount of storage demanded in each cloud. Our investigation of the different energy efficient approaches uses Mixed Integer Linear Programming (MILP) models and real time heuristics.
The IEEE Green ICT initiative is a three-year endeavor launched in January 2015 with the mission to develop a holistic approach to sustainability by incorporating green metrics in various IEEE fields of interest. Following a description of the initiative, this panel session will discuss the broad technology, commercial and policy challenges that must be addressed in order to fully leverage information and communication technologies (ICT) for sustainability purposes.
