Nowadays, Graphics Processing Unit (GPU) is essential for general-purpose high-performance computing, because of its dominant performance in parallel computing compare to that of CPU. There have been many successful trials on the use of GPU in virtualized environment. Especially, NVIDIA Docker obtained a most practical way to bring GPU into the container-based virtualized environment. However, most...
In the last years an increasing number of attacks targeting energy consumption in computing systems have been designed and deployed. In this paper we propose a methodology that can be used to limit the effect of all types of power attacks by using the isolation properties guaranteed by virtualization systems. We describe the idea underlying our approach and we present the power consumption measurements...
Current cloud deployment scenarios imply a need for fast testing of user oriented software in diverse, heterogeneous and often unknown hardware and network environments, making it difficult to ensure optimal or reproducible in-site testing. The current paper proposes the use of container based lightweight virtualization with a ready-to-run, just-intime deployment strategy in order to minimize time...
The integration of Internet of Things (IoT) and Cloud computing has brought the rising of IoT Clouds able to provide different kinds of IoT as a Service solutions consisting of various micro-services deployed in IoT devices (including sensors and actuators) interacting with different Infrastructure, Platform, and Software as Service (i.e., IaaS, PaaS, SaaS) running in the Clouds' data centres. On...
In this paper, we propose an edge computing platform that can coordinate with each computing resources of device, edge node and cloud for diversifying data can be modularized and actively deployed in cooperation within the wide area network. This platform brings transparent processing environment for IoT devices according to a data characteristic or use purpose. We have been developing the platform...
Modern vehicles are equipped with several interconnected sensors on board for monitoring and diagnosis purposes; their availability is a main driver for the development of novel applications in the smart vehicle domain. In this paper, we propose a Docker container-based platform as solution for implementing customized smart car applications. Through a proof-of-concept prototype—developed on a Raspberry...
Proposes an approach to assessing the state of plant species (based on an example of assessing the state of large-leaved linden) in urban environment on the basis of fuzzy information from a group of experts. Formalization of the expert information is carried out on the basis of complete orthogonal semantic spaces. The proposed approach allows to avoid mistakes in the assessment of a single expert...
Cloud computing is an on-demand access model for computing resources most notably embodied by the OpenStack project. As of release Liberty, OpenStack supports provisioning Bare-metal, Virtual machine (VM) and container based hosts. These different hosts incur different overheads. Consequently, the main goal of this paper is to empirically quantify that overhead through a series of experiments. The...
Lightweight virtualization technologies have revolutionized the world of software development by introducing flexibility and innovation to this domain. Although the benefits introduced by these emerging solutions have been widely acknowledged in cloud computing, recent advances have led to the spread of such technologies in different contexts. As an example, the Internet of Things (IoT) and mobile...
Recently, network virtualization technology (NFV) is being studied to reduce network operation cost, mainly in telco companies. Network virtualization technology is a technology that enables software control by abstracting computing, server, and network functions that were formerly hardware-oriented. Network virtualization technology provides the opportunity for small and medium enterprises with technology...
Virtualization is an important technology in data center environment due to its useful features such as server consolidation, power saving, live migration and faster server provisioning. However, virtualization sometimes incurs some performance loss. There are many virtualization approaches including full virtualization and operating system-level virtualization. Different virtualization platforms...
In this paper, we make a case for using lightweight containers for fine-grained resource flexing for Virtualized Network Functions (VNFs) to meet the demands of varying workloads. We quantitatively compare the VNF performance and infrastructure resource usage of three instantiations (bare metal, virtual machine, and container) of three selected VNFs. The three VNFs we experiment with are the Mobility...
Our investigation aims to answer which scenarios LXC, a lightweight virtualization solution, can offer a better performance than KVM, a hypervisor-based virtualization, or even equal to native environments. For that, we are considering HPC I/O bound applications and the effects of resource sharing on the performance of virtualized environments with both tools. We conducted experiments with traditional...
Over the past years the use of digital devices has increased and home networks continue to grow in size and complexity. By the use of virtualized residential gateways advanced functionality can be moved away from the home by extending the customers edge network to the Internet Service Provider (ISP) and thereby decrease the administrative burden for the home user. By employing edge computing and cloud...
The rapid growth of the Internet of Things (IoT) is driving the evolution of Cloud technologies towards resource distribution across multi-clouds and the inclusion of various heterogeneous devices. IoT specific applications may require the deployment of gateways at the network edge to enable its interaction with physical sensors, pre-processing data from these sensors, and synchronizing it with the...
Hypervisor (e.g. KVM) based virtualization has been used as a fundamental technology in cloud computing. However, it has the inherent performance overhead in the virtualized environments, more specifically, the virtualized I/O devices. To alleviate such overhead, PCI passthrough can be utilized to have exclusive access to I/O device. However, this way prevents the I/O device from sharing with multiple...
Cloud computing provides variety of services with the growth of their offerings. Due to efficient services, it faces numerous challenges. It is based on virtualization, which provides users a plethora computing resources by internet without managing any infrastructure of Virtual Machine (VM). With network virtualization, Virtual Machine Manager (VMM) gives isolation among different VMs. But, sometimes...
Bare-metal clouds are an emerging and attractive platform for cloud users who demand extreme computer performance. Bare-metal clouds lease physical machines rather than virtual machines, eliminating a virtualization overhead and providing maximum computer hardware performance. Therefore, bare-metal clouds are suitable for applications that require intensive, consistent, and predictable performance,...
Virtualization is growing rapidly as a result of the increasing number of alternative solutions in this area, and of the wide range of application field. Until now, hypervisor-based virtualization has been the de facto solution to perform server virtualization. Recently, container-based virtualization -- an alternative to hypervisors -- has gained more attention because of lightweight characteristics,...
Containers underwent a whirlwind adoption across cloud providers recently, as the Open Container Initiative works toward standardizing the container format and configuration. The container could become the cloud infrastructure's "narrow waist," bridging a proliferation of existing and emerging cloud services.
