The drastic increase in the usage of handheld devices like smartphones, tablets, etc., produce huge traffic on the Internet which are mainly due the video streaming services applications. Due to the limitations of resources (Power, Memory, Processing, etc.), numerous design patterns of the mobile devices and heterogeneous users' expectations, it is difficult to handle those video streaming services requests. In order to provide an expected experience to the end user and to reduce the burden of the service providers, cloud computing provides the most easy and viable solution. A novel framework in cloud environment has been proposed in this paper to provide a good trade-off between the service handling as well as the user experience. The framework covers various aspects related to streaming services such as user experience, content distribution and retrieval, power usage, network analysis, video storage, device analysis on static and runtime conditions, parallel service provision and the experience perceived by user.

“…Cloud computing can reduce company investments at the start of a business and can also reduce wasted CPU time when the number of concurrent requests is dynamically changed [8]. Cloud computing has been utilized to optimize the performance, reliability, and usability of computing tasks [41,42] and to solve the existing geoscience challenges. Yang [43] reported the utilization of cloud computing to support the intensities of geospatial sciences.…”

Since the Open Geospatial Consortium (OGC) proposed the geospatial Web Processing Service (WPS), standard OGC Web Service (OWS)-based geospatial processing has become the major type of distributed geospatial application. However, improving the performance and sustainability of the distributed geospatial applications has become the dominant challenge for OWSs. This paper presents the construction of an elastic parallel OGC WPS service on a cloud-based cluster and the designs of a high-performance, cloud-based WPS service architecture, the scalability scheme of the cloud, and the algorithm of the elastic parallel geoprocessing. Experiments of the remote sensing data processing service demonstrate that our proposed method can provide a higher-performance WPS service OPEN ACCESSSustainability 2015, 7 14246 that uses less computing resources. Our proposed method can also help institutions reduce hardware costs, raise the rate of hardware usage, and conserve energy, which is important in building green and sustainable geospatial services or applications.

“…When using software emulated IOV methods, the network interfaces are virtual so their internal state is stored into the memory and gets copied as well, thus, the downtime is in the order of a few milliseconds [60]. In the case of direct device assignment and SR-IOV VFs, the internal state of the network interface cannot be copied because it is stored into the hardware that is not able to move [31,120]. The SR-IOV Virtual Function (VF) assigned to the VM will first need to be detached, the live migration will run, and a new VF will be attached at the destination.…”

“…Other works in the context of virtualized HPC clouds with lossless interconnects are mostly limited to pointing out existing issues and demonstrating that the technology has matured enough and virtualization overheads have sufficiently been reduced to make such clouds feasible [29,30,31,32]. Others have focused on cloud tenant isolation at the link level [121,122] while Ranadive, in his doctoral dissertation dedicated his efforts on virtualized resource management with lossless networks [123].…”

The advent of the Internet of Things, sensor and social networks, to mention just a few examples, all contribute towards the solid establishment of the Big Data era. High Performance Computing (HPC) becomes necessary for the efficient processing of the massive amounts of data our society generates, and cloud computing is a critical component to deliver this processing power to a broader audience that cannot afford to acquire and maintain such complex computing systems themselves. However, HPC specific technology and performance is not yet apt to be delivered efficiently over highly flexible and dynamic environments, as typically are the virtualized cloud infrastructures.In this thesis, we address challenges that arise in high performance dynamic cloud environments, that are equipped with HPC specific technology, in the context of networking and virtualization. We use InfiniBand, a high performance lossless interconnection network as the basis of our research, and first show that lossless networks pose prime challenges when the nature of the infrastructure is very dynamic, i.e. exhibits continuous changes. Then we propose a network I/O virtualization architecture, the InfiniBand vSwitch architecture, that can make lossless network technologies more favorable in the cloud. Moreover, we propose different network reconfiguration methods to enable performance-driven reconfigurations in very large network topologies that are commonly found in data centers. Performance-driven reconfigurations are frequently needed to adapt to unpredictable workload changes resulting from the shared and on-demand nature of a cloud platform, or when cloud providers employ live migration of virtual machines to optimize the resource usage of their infrastructure. Last but not least, we propose a new Quality-of-Service metric, called delay, to capture the directly observable service degradation in consolidated cloud environments. We suggest that the delay can be used as a direct service level agreement metric between cloud providers and cloud tenants. AcknowledgementsFirst, I would like to express my gratitude to my three supervisors; Ernst Gunnar Gran, Tor Skeie and Kyrre Begnum. Without their positiveness, supervision, suggestions and encouragement, my PhD journey would not have been so fruitful and enjoyable during both the good and hard times. Then I would like to thank Bjørn Dag Johnsen from Oracle Norway, our closest collaborate in the ERAC project, the project that mainly funded this thesis, for his enthusiastic attitude and participation in the important discussions that shaped the direction of my work and introduced industrial relevance. My appreciation goes as well to Feroz Zahid for being the most easygoing colleague whom I could imagine sharing office with, and a brilliant and ambitious associate, and Sven-Arne Reinemo for his supervision during my early days.A special thank you must be directed to Hårek Haugerud, Anis Yazidi, Hugo Lewi Hammer, Laurence Marie Anna Habib and the whole NETSYS group at the Oslo and Akershus...
