Welcome to this special issue on accelerator virtualization in Concurrency and Computation: Practice Experience. Virtualization is a key technique developed for sharing the underlying physical resources of computer, such as processor or memory network. This enables effective use by improving their utilization reduces costs. A well-known example are virtual machines that have become prominent wi...

With the advent of World Wide Web, the life of every person has changed drastically. No one can imagine a computer without being connected to the Internet. This dependency is likely to grow in coming years with the adoption of technologies like virtualization and cloud computing. Cloud Computing and Virtualization is one of the foremost technology which has attracted many researchers recently, ...

High-data-rate sensing and processing in the field are important for emerging applications in intelligent transportation, surveillance, and environmental management. For these systems, virtualization and virtual data management bring the benefits of easy deployment, flexible control, and strong data containment. Despite limited resources in the field, we show that optimized virtualization suppo...

Virtualization has become apparent in the 1960s as a practice to enhance the use of expensive computing hardware. Virtualization targets to reduce the complexity associated with deployment and maintenance of client devices, which eventually helps IT Companies to reduce system management costs. In this paper, we propose the virtualization concept expanding into many aspects of IT world. There ar...

The swift adoption of cloud services is accelerating the deployment of data centers. These data centers are consuming a large amount of energy, which is expected to grow dramatically under the existing technological trends. Therefore, research efforts are in great need to architect green data centers with better energy efficiency. The most prominent approach is the consolidation enabled by virt...

Software Defined Networks (SDNs) have been recognized as the next-generation networking paradigm that decouples the network control plane from the data forwarding plane. A logically centralized controller is responsible for all the control decisions and communication among the forwarding switches. However, current traffic engineering techniques and state-of-the-art routing algorithms do not eff...

As the size of data and its heterogeneity increase, traditional database system architecture becomes an obstacle to data analysis. Integrating and ingesting (loading) data into databases is quickly becoming a bottleneck in face of massive data as well as increasingly heterogeneous data formats. Still, state-of-the-art approaches typically rely on copying and transforming data into one (or few) ...
