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...
Modern computer systems are designed to balance performance and energy consumption. Several run-time factors, such as concurrency levels, thread mapping strategies, and dynamic voltage and frequency scaling (DVFS) should be considered in order to achieve optimal energy efficiency for a workload. Selecting appropriate run-time factors, however, is one of the most challenging tasks because the run-time...
Battery lifetime, which is one of the most significant user experiences for mobile devices, strongly restricts the functional design of hardware architecture and applications. Among all the aspects of energy saving for mobile devices, energy-aware application design is one of the main areas that has not yet been explored comprehensively. In this paper, we argue for the case for energy-aware mobile...
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...
