Cloud computing has received a significant amount of attentions from both engineering and academic fields. Designing optimal pricing schemes of cloud services plays an important role for the success of cloud computing. How to set optimal prices of cloud resources in order to maximize these CSPs' revenues in an Infrastructure as a Service (IaaS) cloud market while at the same time meeting the cloud...
Performance is one of the main aspects that should be taken into consideration during the design, development, tuning and optimisation of computer networks supported by cloud computing platforms (CCPs). Queueing network models (QNMs) of CCPs constitute essential quantitative tools of investigation towards identifying acceptable levels of quality-of-service (QoS), whether for upgrading an existing...
Deception happens in social life. Social life is now omnipresent in cyber domains. As a result, deception is also evident in cyberspace. Deception in cyberspace is diverse and often differs from traditional social deceptions. Deception has a cost or a loss, often incurred by the victim of the deception. Hence it is important to detect deceptions, and to protect assets. In this work, we carry out analyses...
Todays telecommunication networks are plagued with ever increasing demands of scalability and service agility. Network function virtualization (NFV) potentially addresses the issue of slow scaling and reduced time to introduce new services, which are hindered in network services built up on proprietary, dedicated hardware. In this paper we explore one of the merits of NFV of massive scalability in...
Current PaaS platforms enable single or hybrid cloud deployments. However, such deployment types cannot best cover the user application requirements as they do not consider the great variety of services offered by different cloud providers and the effects of vendor lock-in. On the other hand, multi-cloud deployment enables selecting the best possible service among equivalent ones providing the best...
Cloud Computing has emerged as a service model that enables on-demand network access to a large number of available virtualized resources and applications with a minimal management effort and a minor price. The spread of Cloud Computing technologies allowed dealing with complex applications such as Scientific Workflows, which consists of a set of intensive computational and data manipulation operations...
The adoption of cloud computing is still limited by several legal concerns from companies. One of those reasons is the data sovereignty, as data can be physically host in sensible locations, resulting in a lack of control for companies., In this paper, we present the Nu@ge project aimed at building a federation of container-sized datacenter on the French territory. Nu@ge provides a software stack...
This paper focuses on the resource allocation problem in the context of Cloud Computing. More specifically, this work considers the problem of optimizing the mapping cost of Infrastructure as Cloud Service (IaaS) onto a Networked Edge Data-Centers (DCs) with respect to Quality of Service (QoS) requirements. This work proposes to dynamically partition the networked DCs resources over IaaS requests...
Over the last few years, Big Data analysis (i.e., crunching enormous amounts of data from different sources to extract useful knowledge for improving business objectives) has attracted huge attention from enterprises and research institutions. One of the most successful paradigms that has gained popularity in order to analyse this huge amount of data, is MapReduce (and particularly Hadoop, its open...
Cloud computing is an utility computing paradigm that allows users to flexibly acquire virtualized computing resources in a pay-as-you-go model. To realize the benefits of using cloud, users need to first select the suitable cloud services that can satisfy their applications' functional and non-functional requirements. However, this is a difficult task due to large number of available services, users'...
Monitoring of resources is one among the major challenges that the virtualization brings with it within the Cloud environment since the user applications are often distributed on several nodes whose location is unknown a priori and can dynamically change. Consumers need to monitor their resources for checking that service levels are continuously compliant with the agreed SLA and for detecting under-utilization...
The growing number of cloud services have made service selection a challenging decision-making problem by providing wide ranging choices for cloud service consumers. This necessitates the use of formal decision making methodologies to assist a decision maker in selecting the service that best fulfils the user's requirements. In this paper, we present a cloud service selection methodology that utilizes...
Virtualization Technology is the most important base for IaaS (Infrastructure as a Service) cloud computing platform. VM (Virtual Machine) Motion is the main means for IaaS platform to realize resource reallocation, disaster recovery, load balance and etc. Virtual machine motion can help cloud computing platform to release resources, optimize the resources usage, increase the VM capacity, so as to...
Cloud computing has been established in recent years as an important area of research. This reality has been consolidated because, currently, tasks such as obtainment, manipulation, sharing and exploitation of large amounts of data are common and require many computational resources, so cloud computing can contribute because it can provide this resources indefinitely, including processing, memory,...
Most Infrastructure As A Service (IaaS) cloud platforms are implemented with a cluster of machines having multiple worker nodes and a single master node, which acts as the cloud front-end. In such an architecture the control regarding the Virtual Machine (VM) scheduling and policies compliance etc. lies largely with the front-end node of the cluster. Decision making in such IaaS cloud does not have...
