Resource provisioning remains as one of the challenging research problems in cloud computing, more importantly when considered together with service reliability. Fault-tolerance techniques such as fault-recovery is one of the techniques that can be employed to improve on service reliability. Technically, fault-recovery has obvious impact on service performance. Such impact requires detailed stu...

The continuous increase of unbound streaming data poses several challenges to established data stream processing engines. One of the most important challenges is the cost-efficient enactment of stream processing topologies under changing data volume. These data volume pose different loads to stream processing systems whose resource provisioning needs to be continuously updated at runtime. First...

Advancements in wireless networks and mobile device capabilities enable ubiquitous access for Web resources anywhere anytime. Web service technologies enable rapid and low-cost development of networked and portable applications. The successful convergence of these technologies produces mobile Web services provisioning, where mobile devices can host and provide Web services. However, the resourc...

Resource provisioning refers to the dedicated use of certain set of resources for certain timeframe. In this paper, we study the effect of using resource provisioning on the completion time of workflows, represented as a directed acyclic graph (DAG). Provisioning can be done statically using advance reservations or using dynamic provisioning mechanisms such as Condor Glidein. A simulation is do...

Network slicing allows Mobile Operators to split the physical infrastructure into isolated virtual networks (slices), managed by Service Providers accommodate customized services. The Function Chains (SFCs) belonging a slice are usually deployed on best-effort premise: nothing guarantees that network resources will be sufficient support varying number of users, each with uncertain requirements....

This deliverable specifies the traffic handling mechanisms for the second trial. Traffic handling in AQUILA is composed of four related mechanisms operating at different time scales: provisioning (days to weeks), resource pools (hours), admission control (seconds to minutes), traffic control (milliseconds). Keyword List: AQUILA, QoS, Internet, Traffic Control, Admission Control, MBAC, Provision...

In resource provisioning for datacenters, an important issue is how resources may be allocated to an application such that the service level agreements (SLAs) are met. Resource provisioning is usually guided by intuitive or heuristic expectation of performance and existing user model. Provisioning based on such methodology, however, usually leads to more resources than are actually necessary. W...

Most existing virtual network (VN) provisioning approaches assume a single administrative domain and therefore, VN deployments are limited to the geographic footprint of the substrate provider. To enable wide-area VN provisioning, network virtualization architectures need to address the intricacies of inter-domain aspects, i.e., how to provision VNs with limited control and knowledge of any asp...
