The huge energy consumption in data centers produces not only high electricity bill but also tremendous carbon footprints. Although today's servers and data centers of leading internet companies are more energy efficient than ever before, the fluctuations in external workload and internal resource utilization calls for energy proportional computing. Insight into server energy proportionality can help...
the recent development of Information and Communications Technology (ICT) has contributed to an explosive growth of high-volume, high-velocity and high-variety information assets. Consequently, the concept of Big Data has emerged as a widely recognized trend. In order to accommodate these data-intensive services, a sustainable and resilient network infrastructure is essentially needed, as well as...
Current cloud data centers are fully virtualized for service consolidations and power/energy reduction. Although virtualization could reduce real time power and overall energy consumption, the energy characteristics of hypervisors hosting different workloads are not well profiled and understood. In this paper, we investigate the power and energy characteristics of mainstream hypervisors and container...
Cloud networking is rapidly growing as a new emerging information platform to deliver services and share resources, which becomes an alternative to conventional computer networking. The cloud computing offers many advanced functionalities, but it still has some challenging problems to be solved such as the energy efficiency and service resilience. Therefore, the critical concerns on network sustainability...
