Federated Networking Services in Multiple OpenStack Clouds
Advances in Service-Oriented and Cloud Computing, 2016Co-Authors: Antonio Celesti, Philippe Massonet, Anna Levin, Liran Schour, Massimo VillariAbstract:Cloud federation refers to a mesh of Cloud providers that are interconnected by using agreements and protocols necessary to provide a decentralized computing environment. Federation is raising many challenges in different research fields but is also creating new business opportunities. Nowadays, the combination between Cloud federation, Software Defined Networking (SDN), and Network Function Virtualization (NFV) technologies offers new business opportunities to Cloud providers that are able to offer new innovative federated Cloud Networking services to customers. In this paper, we focus on federated Cloud Networking services considering multiple OpenStack Clouds. In particular, we present a preliminary outcome of an innovative design of a Federation Management system acting as an external service provider dealing with federated Networking services among multiple federated OpenStack Clouds. More specifically, we describe how virtual resources, virtual Networking, and security management can be accomplished.

Broker and Federation Based Cloud Networking Architecture for IaaS and NaaS QoS Guarantee
2016Co-Authors: Mohamad Hamze, Nader Mbarek, Olivier TogniAbstract:Today, the Cloud Networking aspect is a critical factor for adopting the Cloud computing approach. The main drawback of Cloud Networking consists in the lack of Quality of Service (QoS) guarantee and management in conformance with a corresponding Service Level Agreement (SLA). This paper presents a framework for resource allocation according to an end-to-end SLA established between a Cloud Service User (CSU) and several Cloud Service Providers (CSPs) in a Cloud Networking environment. We focus on QoS parameters for Network as a Service (NaaS) and Infrastructure as a Service (IaaS) services. In addition, we propose algorithms for the best CSPs selection to allocate Virtual Machines (VMs) and network resources in inter-Cloud broker and federation scenarios. Our objective is to minimize the cost while satisfying NaaS and IaaS QoS constraints. Moreover, we simulate our proposed Cloud Networking architecture to provide videoconferencing and intensive computing applications with QoS guarantee. We observe that the broker architecture is the most interesting while ensuring QoS requirements.

International journal of new computer architectures and their applications (IJNCAA), 2015Co-Authors: Mohamad Hamze, Nader Mbarek, Olivier TogniAbstract:Today, Cloud Networking which is the ability to connect users with their Cloud services and to interconnect these services in an inter-Cloud approach, is one of the recent research areas within the Cloud computing research communities. The main drawback of Cloud Networking consists in the lack of Quality of Service (QoS) guarantee and management in conformance with a corresponding Service Level Agreement. In this paper, a framework is proposed for resource allocation according to an end-to-end service level agreement established between a Cloud Service User and several Cloud Service Providers within a Cloud Networking environment. The paper focuses on QoS parameters for NaaS and IaaS services. In addition, several algorithms are proposed for the best Cloud Service Providers selection to allocate VMs and network resources within a Broker and a Federation based inter-Cloud scenarios. The objective is to minimize the total cost while satisfying NaaS and IaaS QoS constraints. Moreover, the proposed Cloud Networking architecture is used to provide videoconferencing and intensive computing applications with QoS guarantee. The corresponding scenarios are simulated using an extended CloudSim toolkit. The results reveal a high scalability and good performances where the Broker architecture is the most interesting while ensuring QoS requirements.

Resource Self-management under an SLA within a Cloud Networking Environment
2015Co-Authors: Mohamad Hamze, Nader Mbarek, Olivier TogniAbstract:Today, Cloud Networking is one of the recent research areas in the Cloud computing research communities. The main drawback of Cloud Networking consists in the lack of Quality of Service (QoS) guarantee and management in conformance with a corresponding Service Level Agreement (SLA). In this paper, we propose a framework for self-establishing an end-to-end SLA between a Cloud Service User (CSU) and several Cloud Service Providers (CSPs) in a Cloud Networking environment (inter-Cloud Broker and Federation architecture). Then, we propose the self-management of Cloud resources under the established SLA using specific autonomic Cloud managers. We simulate our proposed framework to provide videoconferencing and intensive computing applications with self-management and QoS guarantee. We observe that the Broker architecture is the most economical, while ensuring QoS requirements.

Self-establishing a Service Level Agreement within Autonomic Cloud Networking Environment
2014Co-Authors: Mohamad Hamze, Nader Mbarek, Olivier TogniAbstract:Today, Cloud Networking which is the ability to connect the user with his Cloud services and to interconnect these services within an inter-Cloud approach, is one of the recent research areas in the Cloud computing research communities. The main drawback of Cloud Networking consists in the lack of Quality of Service (QoS) guarantee and management in conformance with a corresponding Service Level Agreement (SLA). Several research works have been proposed for the SLA establishing in Cloud computing, but not in Cloud Networking. In this paper, we propose an architecture for self-establishing an end-to-end service level agreement between a Cloud Service User (CSU) and a Cloud Service Provider (CSP) in a Cloud Networking environment. We focus on QoS parameters for NaaS and IaaS services. The architecture ensures a self-establishing of the proposed SLA using autonomic Cloud managers.

Resource Management in Cloud Networking Using Economic Analysis and Pricing Models: A Survey
IEEE Communications Surveys & Tutorials, 2017Co-Authors: Nguyen Cong Luong, Yonggang Wen, Dusit Niyato, Ping Wang, Zhu HanAbstract:This paper presents a comprehensive literature review on applications of economic and pricing models for resource management in Cloud Networking. To achieve sustainable profit advantage, cost reduction, and flexibility in provisioning of Cloud resources, resource management in Cloud Networking requires adaptive and robust designs to address many issues, e.g., resource allocation, bandwidth reservation, request allocation, and workload allocation. Economic and pricing models have received a lot of attention as they can lead to desirable performance in terms of social welfare, fairness, truthfulness, profit, user satisfaction, and resource utilization. This paper reviews applications of the economic and pricing models to develop adaptive algorithms and protocols for resource management in Cloud Networking. Besides, we survey a variety of incentive mechanisms using the pricing strategies in sharing resources in edge computing. In addition, we consider using pricing models in Cloud-based Software Defined Wireless Networking (Cloud-based SDWN). Finally, we highlight important challenges, open issues and future research directions of applying economic and pricing models to Cloud Networking

Autonomie, sécurité et QoS de bout en bout dans un environnement de Cloud Computing
2015Co-Authors: Mohamad HamzeAbstract:De nos jours, le Cloud Networking est considéré comme étant l'un des domaines de recherche innovants au sein de la communauté de recherche du Cloud Computing. Les principaux défis dans un environnement de Cloud Networking concernent non seulement la garantie de qualité de service (QoS) et de sécurité mais aussi sa gestion en conformité avec un accord de niveau de service (SLA) correspondant. Dans cette thèse, nous proposons un Framework pour l'allocation des ressources conformément à un SLA établi de bout en bout entre un utilisateur de services Cloud (CSU) et plusieurs fournisseurs de services Cloud (CSP) dans un environnement de Cloud Networking (architectures d’inter-Cloud Broker et Fédération). Nos travaux se concentrent sur les services Cloud de types NaaS et IaaS. Ainsi, nous proposons l'auto-établissement de plusieurs types de SLA ainsi que la gestion autonome des ressources de Cloud correspondantes en conformité avec ces SLA en utilisant des gestionnaires autonomes spécifiques de Cloud. De plus, nous étendons les architectures et les SLA proposés pour offrir un niveau de service intégrant une garantie de sécurité. Ainsi, nous permettons aux gestionnaires autonomes de Cloud d'élargir leurs objectifs de gestion autonome aux fonctions de sécurité (auto-protection) tout en étudiant l'impact de la sécurité proposée sur la garantie de QoS. Enfin, nous validons notre architecture avec différents scénarios de simulation. Nous considérons dans le cadre de ces simulations des applications de vidéoconférence et de calcul intensif afin de leur fournir une garantie de QoS et de sécurité dans un environnement de gestion autonome des ressources du Cloud. Les résultats obtenus montrent que nos contributions permettent de bonnes performances pour ce type d’applications. En particulier, nous observons que l'architecture de type Broker est la plus économique, tout en assurant les exigences de QoS et de sécurité. De plus, nous observons que la gestion autonome des ressources du Cloud permet la réduction des violations, des pénalités et limite l'impact de la sécurité sur la garantie de la QoS.
