Conventional and virtualization-based implementations in operator networks are analyzed based on a realistic use case in terms of cost and energy efficiency. The results show advantages for the virtualization-based solutions as the systems' utilization as a key factor is improved.
Performance and energy efficiency are major concerns in cloud computing data centers. More often, they carry conflicting requirements making optimization a challenge. Further complications arise when heterogeneous hardware and data center management technologies are combined. For example, heterogeneous hardware such as General Purpose Graphics Processing Units (GPGPUs) improve performance at the cost...
One of the key goals of Network Functions Virtualization (NFV) is achieving energy efficiency through workload consolidation. A good example for maximizing energy savings is the Virtualization of Content Delivery Networks (vCDNs) NFV use case where the video streaming workloads exhibit significant difference between prime-time and non-prime-time usage of the infrastructure. This paper examines the...
EUROSERVER is a collaborative project that aims to dramatically improve data centre energy-efficiency, cost, and software efficiency. It is addressing these important challenges through the coordinated application of several key recent innovations: 64-bit ARM cores, 3D heterogeneous silicon-on-silicon integration, and fully-depleted silicon-on-insulator (FD SOI) process technology, together with new...
Wireless Sensor Network (WSN) has led to a new paradigm of Internet of Things (IoT). WSNs are usually deployed for particular application. However, the future of WSNs in Smart Home and Ambient Assisted Living (SHAAL) lies in the aggregation and allocation of resources serving diverse applications. Virtualization of a sensor network is an emerging concept that enables aggregation of multiple independent...
Energy consumption of data centers has been in-creasing continuously during the last years due to rising demands of computational power especially in current Grid- and Cloud-Computing systems. One promising approach of reducing this energy consumption is the consolidation of servers by virtualization. Many low loaded computer systems are virtualized and run on few physical servers for reducing the...
Rapid growth of the demand for computational power by scientific, business and web-applications has led to the creation of large-scale data centers consuming enormous amounts of electrical power. We propose an energy efficient resource management system for virtualized Cloud data centers that reduces operational costs and provides required Quality of Service (QoS). Energy savings are achieved by continuous...
Energy efficiency in the field of information and communication technology becomes increasingly important due to the increase in energy costs and the desire to reduce CO2 emissions. Office environments of public administration and companies promise high potential in terms of energy saving. In such environments a high number of hosts are operating on a 24/7 basis. This paper suggests an Energy-Efficient...
