Full textAbstract:
One of the biggest challenges in cloud federations is how to express the federation level agreement (FLA) and voluntary aspect of the federation members and maintain the integrity of the organization. However, existing works are not able to present the cloud federation management aspect or implement these properties that distinguish cloud federation from other inter-cloud organizations. This paper bridges this gap by proposing a managed cloud federation architecture based on this subset of properties. The key component of this architecture is the federation manager that controls, tracks, evaluates, and predicts the behavior of the federation. In order to ensure the effectiveness of the approach, the authors developed the Managed Federation Simulator to implement the proposed federation architecture on the SmartFed simulator and evaluate it through a set of scenarios on a real case study.

Full textAbstract:
Resource sharing can gain economies of scale and increase utilization of cloud infrastructure, a critical challenge of which is how to design efficient resource sharing solutions among self-interested cloud providers. Cloud federation can realize resource sharing, but the existing methods of forming federation need complex computation to guarantee the stability of federation. To address this shortcoming, after analyzing an optimal allocation approach of service requests among clouds, we propose a pareto optimal resource sharing solution named Cloud Light-Federation Sharing (CLFS), in which each cloud can choose its own optimal strategies individually and federation can be formed without complex computation for allocation of service requests and profits. In addition, an optimal resource sharing solution named Cloud Cooperative-Federation Sharing (CCFS) was also designed, in which cloud providers are fully cooperative and have fair profit allocation. The experimental results show that the two federation methods can significantly improve the total utility and decrease the number of dropped jobs. Although the federation rules of Cloud Light-Federation Sharing are simple, its performance is still very close to that of Cloud Cooperative-Federation Sharing.

The academic de.NBI Cloud offers compute resources for life science research in Germany. At the beginning of 2017, de.NBI Cloud started to implement a federated cloud consisting of five compute centers, with the aim of acting as one resource to their users. A federated cloud introduces multiple challenges, such as a central access and project management point, a unified account across all cloud sites and an interchangeable project setup across the federation. In order to implement the federation concept, de.NBI Cloud integrated with the ELIXIR authentication and authorization infrastructure system (ELIXIR AAI) and in particular Perun, the identity and access management system of ELIXIR. The integration solves the mentioned challenges and represents a backbone, connecting five compute centers which are based on OpenStack and a web portal for accessing the federation.This article explains the steps taken and software components implemented for setting up a federated cloud based on the collaboration between de.NBI Cloud and ELIXIR AAI. Furthermore, the setup and components that are described are generic and can therefore be used for other upcoming or existing federated OpenStack clouds in Europe.

Full textAbstract:
Cloud Computing has become the popular paradigm for accessing the various scalable and on-demand computing services over the internet. Nowadays, individual Cloud Service Providers (CSPs) offering specialized services to the customers collaborate to form the Cloud Federation, in order to reap the real benefits of Cloud Computing. By collaboration, the member CSPs of the federation achieve better resource utilization and Quality of Service (QoS), thereby increasing their business prospects. When a CSP runs out of resources in the Cloud Federation, in order to offload the customer requests for resources to other CSP(s), identifying a suitable partner is a challenging task due to the lack of global coordination among them. In this paper, we propose the design and implementation of an efficient partner selection mechanism in the Cloud Federation, using the Analytic Hierarchy Process (AHP) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods, and also considering the trust values of various CSPs in the federation. The AHP method is used to calculate the weights of the QoS parameters used in the TOPSIS method which is used to rank the various CSPs in the Cloud Federation according to the user requirements. Simulation results show the effectiveness of this approach in order to efficiently select the trustworthy partners in large scale federations to ensure the required QoS to the cloud consumers.

Full textAbstract:
Kubernetes, a container orchestration tool for automatically installing and managing Docker containers, has recently begun to support a federation function of multiple Docker container clusters. This technology, called Kubernetes Federation, allows developers to increase the responsiveness and reliability of their applications by distributing and federating container clusters to multiple service areas of cloud service providers. However, it is still a daunting task to manually manage federated container clusters across all the service areas or to maintain the entire topology of cloud applications at a glance. This research work proposes a method to automatically form and monitor Kubernetes Federation, given application topology descriptions in TOSCA (Topology and Orchestration Specification for Cloud Applications), by extending the orchestration tool that automatizes the modeling and instantiation of cloud applications. It also demonstrates the successful federation of the clusters according to the TOSCA specifications and verifies the auto-scaling capability of the configured system through a scenario in which the servers of a sample application are deployed and federated.

The increasing demand of the cloud services and with the emergence of many could service providers, the need for cloud federation is inevitable. In cloud federation, many could services providers are collaborating with each other to improve the resources usage, cost, quality of service they provide. To form this federation a management framework is required to facilitate the communication between these providers. This framework can be centralized or distributed, distributed Peer to Peer cloud federation improve extensibility, scalability and fault-tolerant. On the other hand, it is challenging in term of complexity, security and manageability of the federation. In this paper we propose a fully distributed P2P Cloud Federation (PPCF) architecture. PPCF provide a way to connect heterogenous cloud providers to share resources and improve the cloud elasticity. The architecture combines different software technologies to fulfil the cloud federation requirements.

The EGI Cloud Compute service offers a multi-cloud IaaS federation that brings together research clouds as a scalable computing platform for research accessible with OpenID Connect Federated Identity. The federation is not limited to single sign-on, it also introduces features to facilitate the portability of applications across providers: i) a common VM image catalogue VM image replication to ensure these images will be available at providers whenever needed; ii) a GraphQL information discovery API to understand the capacities and capabilities available at each provider; and iii) integration with orchestration tools (such as Infrastructure Manager) to abstract the federation and facilitate using heterogeneous providers. EGI also monitors the correct function of every provider and collects usage information across all the infrastructure. DODAS (Dynamic On Demand Analysis Service) is an open-source Platform-as-a-Service tool, which allows to deploy software applications over heterogeneous and hybrid clouds. DODAS is one of the so-called Thematic Services of the EOSC-hub project and it instantiates on-demand container-based clusters offering a high level of abstraction to users, allowing to exploit distributed cloud infrastructures with a very limited knowledge of the underlying technologies.This work presents a comprehensive overview of DODAS integration with EGI Cloud Federation, reporting the experience of the integration with CMS Experiment submission infrastructure system.

L'informatique en nuage (Cloud Computing) est un modèle à grande échelle et en évolution continue, permettant le provisionnement et l'utilisation des ressources informatiques à la demande, selon un modèle rentable de facturation à l'usage "pay-as-you-go". Ce nouveau paradigme a rapidement révolutionné l'industrie IT et a permis de nouvelles tendances en matière de prestation de services informatiques, y compris l'externalisation des infrastructures IT vers des prestataires tiers spécialisés. Cependant, la nature multi-utilisateur des plateformes d'hébergement, ainsi que la complexité des demandes, soulèvent plusieurs défis liés à la gestion des ressources Cloud. Malgré l'attention croissante portée à ce sujet, la plupart des efforts ont été axés sur des solutions centrées utilisateur, et malheureusement beaucoup moins sur les difficultés rencontrées par les fournisseurs pour maximiser leurs bénéfices. Dans ce contexte, la fédération de Cloud a été récemment proposée comme une solution clé pour répondre à l'augmentation et la fluctuation des charges de travail. Les fournisseurs ayant des besoins complémentaires en ressources au fil du temps, peuvent collaborer et partager leurs infrastructures respectives via l'externalisation ("Outsourcing") pour mieux satisfaire les demandes et exigences des utilisateurs. Cette thèse aborde le problème d'optimisation du profit via la fédération et l'allocation optimale des ressources parmi plusieurs fournisseurs d'infrastructures Cloud. L'étude examine les principaux défis et opportunités liés à la maximisation des revenus dans une fédération de Clouds, et définit des stratégies efficaces pour diriger les fournisseurs dans leurs décisions de coopération. Le but est de fournir des algorithmes qui automatisent la sélection du plan d'allocation le plus rentable, qui satisfait à la fois la demande des utilisateurs et les exigences de mise en réseau. Nous visons des modèles d'allocation génériques et robustes qui répondent aux nouvelles tendances Cloud, et de traiter les requêtes simples ainsi que complexes nécessitant le provisionnement de services composites avec différentes ressources distribuées et connectées. Conformément aux objectifs de la thèse, nous avons mené une étude approfondie des travaux antérieurs traitant la problématique de provisionnement des ressources d'infrastructure dans les environnements Cloud. L'analyse a porté notamment sur les modèles d'allocation ayant pour objectif la maximisation de profit et les lacunes et défis associés dans les fédérations de Clouds. Dans un deuxième temps, nous avons proposé un programme linéaire en nombre entiers (ILP), pour aider les fournisseurs de services dans leurs décisions de coopération via des actions optimales d'externalisation (outsourcing), d'internalisation (insourcing) et d'allocation en local. Ces différentes décisions d'allocation sont traitées conjointement dans une formule d'optimisation globale qui partitionne les graphes de requêtes entre les membres de la fédération, tout en satisfaisant les exigences de communication entre les services élémentaires. En plus de la topologie des graphes de ressources, ce partitionnement prend en compte les prix dynamiques et les quotas proposés par les membres de la fédération ainsi que les coûts d'hébergement des ressources et de leur mise en réseau. Enfin, nous avons proposé un algorithme heuristique pour améliorer les temps de convergence avec les instances de problèmes à grande échelle. L'approche proposée utilise un algorithme de "clustering" basé sur les arbres de Gomory-Hu pour le partitionnement des graphes et une stratégie de meilleur ajustement (Best-Fit matching) pour l'allocation et le placement des sous-graphes résultants. L'utilisation conjointe de ces deux techniques permet de capturer l'essence du problème d'optimisation et de respecter les différents objectifs fixés, tout en améliorant le temps de convergence vers les solutions quasi-optimales de plusieurs ordres de grandeurCloud computing is a steadily maturing large-scale model for providing on-demand IT resources on a pay-as-you-go basis. This emerging paradigm has rapidly revolutionized the IT industry and enabled new service delivery trends, including infrastructure externalization to large third-party providers. The Cloud multi-tenancy architecture raises several management challenges for all stakeholders. Despite the increasing attention on this topic, most efforts have been focused on user-centric solutions, and unfortunately much less on the difficulties encountered by Cloud providers in improving their business. In this context, Cloud Federation has been recently suggested as a key solution to the increasing and variable workloads. Providers having complementary resource requirements over time can collaborate and share their respective infrastructures, to dynamically adjust their hosting capacities in response to users' demands. However, joining a federation makes the resource allocation more complex, since providers have to also deal with cooperation decisions and workload distribution within the federation. This is of crucial importance for cloud providers from a profit standpoint and especially challenging in a federation involving multiple providers and distributed resources and applications. This thesis addresses profit optimization through federating and allocating resources amongst multiple infrastructure providers. The work investigates the key challenges and opportunities related to revenue maximization in Cloud federation, and defines efficient strategies to govern providers' cooperation decisions. The goal is to provide algorithms to automate the selection of cost-effective distributed allocation plans that simultaneously satisfy user demand and networking requirements. We seek generic and robust models able to meet the new trends in Cloud services and handle both simple and complex requests, ranging from standalone VMs to composite services requiring the provisioning of distributed and connected resources. In line with the thesis objectives, we first provide a survey of prior work on infrastructure resource provisioning in Cloud environments. The analysis mainly focuses on profit-driven allocation models in Cloud federations and the associated gaps and challenges with emphasis on pricing and networking issues. Then, we present a novel exact integer linear program (ILP), to assist IaaS providers in their cooperation decisions, through optimal "insourcing", "outsourcing" and local allocation operations. The different allocation decisions are treated jointly in a global optimization formulation that splits resource request graphs across federation members while satisfying communication requirements between request subsets. In addition to the request topology, this partitioning takes into account the dynamic prices and quotas proposed by federation members as well as the costs of resources and their networking. The algorithm performance evaluation and the identified benefits confirm the relevance of resource federation in improving providers' profits and shed light into the most favorable conditions to join or build a federation. Finally, a new topology-aware allocation heuristic is proposed to improve convergence times with large-scale problem instances. The proposed approach uses a Gomory-Hu tree based clustering algorithm for request graphs partitioning, and a Best-Fit matching strategy for subgraphs placement and allocation. Combining both techniques captures the essence of the optimization problem and meets the objectives, while speeding up convergence to near-optimal solutions by several orders of magnitude

Distributed Real-Time Media Processing refers to classes of highly distributed, delay no-tolerant applications that account for the majority of the data traffic generated in the world today. Real-Time audio/video conferencing and live content streaming are of particular research interests as technology forecasts predict video traffic surpassing every other type of data traffic in the world in the near future. These applications are very sensitive to both communication properties such as latency, jitter, packet loss, bit rate as well as backend stream processing load profiles. In this work we provide a novel and generalized large-scale Multi-Cloud architectural blueprint for ISP and Carrier providers, that permits smart geo-distributed service placement in order to optimize latency/locality of stream processing applications. We provide as a well self-managed Intra-Cloud federation algorithm based on gradient topologies in order to optimize routes in a live media streaming backend. Additionally we introduce a novel distributed Network Bandwidth Manager that optimizes system stability by arbitrating network bandwidth between multiple Cloud services sharing the same network infrastructure. At last, an empirical study is provided connecting media quality parameters and Cloud backend load profiles, including an algorithm for stream allocation on Cloud Selective Forwarding units.El procesamiento de medios en tiempo real distribuido se refiere a clases de aplicaciones altamente distribuidas, no tolerantes al retardo, que representan la mayoría del tráfico de datos generado en el mundo actual. Las conferencias de audio y video en tiempo real y la transmisión de contenido en vivo tienen especial interés en investigación, ya que la prospectiva tecnológica estima que el tráfico de video supere a cualquier otro tipo de tráfico de datos en el futuro cercano. La transmisión en vivo se refiere a aplicaciones en las que flujos de audio/vídeo de una fuente se han de entregar a un conjunto de destinos en lugares geográficos diferentes mientras se mantiene baja la latencia de entrega del flujo (como por ejemplo la cobertura de eventos en vivo). Las plataformas de conferencia en tiempo real son plataformas de aplicación que implementan comunicaciones de audio/video en tiempo real entre muchos participantes. Ambas categorías presentan una alta sensibilidad tanto al estado de la red (latencia, jitter, pérdida de paquetes, velocidad de bits) como a los perfiles de carga de la infraestructura de procesamiento de flujo (latencia y jitter introducidos durante el procesamiento en la nube de paquetes de datos multimedia). Esta tesis trata de mejorar el procesamiento de datos multimedia en tiempo real tanto en los parámetros de nivel de red como en las optimizaciones en la nube.

The evolution of software service delivery has changed the way accountability is performed. The complexity related to cloud computing environments increases the difficulty in properly performing accountability, since the evidences are spread through the whole infrastructure, from different servers, in physical, virtualization and application layers. This complexity increases when the cloud federation is considered because besides the inherent complexity of the virtualized environment, the federation members may not implement the same security procedures and policies. The main objective of this thesis is to propose an accountability framework named CloudAcc, that supports audit, management, planning and billing process in federated cloud environments, increasing trust and transparency. Furthermore, CloudAcc considers the legal safeguard requirements presented in Brazilian Marco Civil da Internet. We confirm the CloudAcc effectiveness when some infrastructure elements were submitted against Denial of Service (DoS) and Brute Force attacks, and our framework was able to detect them. Facing the results obtained, we can conclude that CloudAcc contributes to the state-of-the-art once it provides the holistic vision of the cloud federated environment through the evidence collection considering the three layers, supporting audit, management, planning and billing process in federated cloud environments.
A maneira de realizar accountability tem variado à medida em que o modo de entrega de serviços de Tecnologia da Informação (TI) tem evoluído. Em ambientes de nuvem a complexidade de realizar accountability apropriadamente é alta porque as evidências devem ser coletadas considerando-se as camadas física, de virtualização e de aplicações, que estão espalhadas em diferentes servidores e elementos da infraestrutura. Esta complexidade é ampliada quando ocorre a federação das infraestruturas de nuvem porque além da complexidade inerente ao ambiente virtualizado, os membros da federação podem não ter os mesmos grupos de políticas e práticas de segurança. O principal objetivo desta tese é propor um framework de accountability, denominado CloudAcc, que suporte processos de auditoria, gerenciamento, planejamento e cobrança, em nuvens federadas, aumentando a confiança e a transparência. Além disso, o CloudAcc também considera os requisitos legais para a salvaguarda dos registros, conforme descrito no Marco Civil da Internet brasileira. A efetividade do CloudAcc foi confirmada quando alguns componentes da infraestrutura da nuvem foram submetidos a ataques de negação de serviço e de força bruta, e o framework foi capaz de detectá-los. Diante dos resultados obtidos, pode-se concluir que o CloudAcc contribui para o estado-da-arte, uma vez que fornece uma visão holística do ambiente de nuvem federada através da coleta de evidências em três camadas suportando os processos de auditoria, gerenciamento, planejamento e cobrança.

MCC (Mobile Cloud Computing) est un candidat très fort pour le NGN (Next Generation Network) qui permet aux utilisateurs mobiles d’avoir une mobilité étendue, une continuité de service et des performances supérieures. Les utilisateurs peuvent s’attendre à exécuter leurs travaux plus rapidement, avec une faible consommation de batterie et à des prix abordables ; mais ce n’est pas toujours le cas. Diverses applications mobiles ont été développées pour tirer parti de cette nouvelle technologie, mais chacune de ces applications possède ses propres exigences. Plusieurs MCA (Mobile Cloud Architectures) ont été proposées, mais aucune n'a été adaptée pour toutes les applications mobiles, ce qui a mené à une faible satisfaction du client. De plus, l'absence d'un modèle d'affaires (business model) valide pour motiver les investisseurs a empêché son déploiement à l'échelle de production. Cette thèse propose une nouvelle architecture de MCA (Mobile Cloud Architecture) qui positionne l'opérateur de téléphonie mobile au cœur de cette technologie avec un modèle d'affaires de recettes. Cette architecture, nommée OCMCA (Operator Centric Mobile Cloud Architecture), relie l'utilisateur d’un côté et le fournisseur de services Cloud (CSP) de l'autre côté, et héberge un cloud dans son réseau. La connexion OCMCA / utilisateur peut utiliser les canaux multiplex menant à un service beaucoup moins cher pour les utilisateurs, mais avec plus de revenus, et de réduire les embouteillages et les taux de rejet pour l'opérateur. La connexion OCMCA / CSP est basée sur la fédération, ainsi un utilisateur qui a été enregistré avec n’importe quel CSP, peut demander que son environnement soit déchargé de cloud hébergé par l'opérateur de téléphonie mobile afin de recevoir tous les services et les avantages de OCMCA.Les contributions de cette thèse sont multiples. Premièrement, nous proposons OCMCA et nous prouvons qu'il a un rendement supérieur à toutes les autres MCA (Mobile Cloud Architectures). Le modèle d'affaires (business model) de cette architecture se concentre sur la liberté de l'abonnement de l'utilisateur, l'utilisateur peut ainsi être abonné à un fournisseur de cloud et être toujours en mesure de se connecter via cette architecture à son environnement à l'aide du déchargement et de la fédérationMobile cloud computing is a very strong candidate for the title "Next Generation Network" which empowers mobile users with extended mobility, service continuity and superior performance. Users can expect to execute their jobs faster, with lower battery consumption and affordable prices; however this is not always the case. Various mobile applications have been developed to take advantage of this new technology, but each application has its own requirements. Several mobile cloud architectures have been proposed but none was suitable for all mobile applications which resulted in lower customer satisfaction. In addition to that, the absence of a valid business model to motivate investors hindered its deployment on production scale. This dissertation proposes a new mobile cloud architecture which positions the mobile operator at the core of this technology equipped with a revenue-making business model. This architecture, named OCMCA (Operator Centric Mobile Cloud Architecture), connects the user from one side and the Cloud Service Provider (CSP) from the other and hosts a cloud within its network. The OCMCA/user connection can utilize multicast channels leading to a much cheaper service for the users and more revenues, lower congestion and rejection rates for the operator. The OCMCA/CSP connection is based on federation, thus a user who has been registered with any CSP, can request her environment to be offloaded to the mobile operator's hosted cloud in order to receive all OCMCA's services and benefits

Das Internet of Things (IoT) ist aktuell ein junger Wachstumsmarkt, dessen Bedeutung für unsere Gesellschaft in naher Zukunft vielen Menschen erst noch wirklich bewusst werden wird. Die Subdomänen Smart-Home, Smart-Grid, Smart-Mobility, Industrie 4.0, Smart-Health und viele mehr sind wichtig für unsere zukünftige Wettbewerbsfähigkeit, die Herausforderungen zur Bewältigung des Klimawandels, unsere Gesundheit, aber auch für trivialere Dinge wie Komfort. Andererseits ergibt sich hierbei bereits dasselbe große Problem, das in einer ähnlichen Form schon bei klassischem Cloud-Computing bekannt ist: Vendor-Silos, die keinen hersteller- oder anbieterübergreifenden Austausch von Gerätedaten ermöglichen, verhindern eine schnelle Verbreitung dieser neuen Technologie. Diensteanbieter müssen ihre Produkte aufwendig für unzählige Technologien bereitstellen, was die Entwicklung von Diensten unnötig teuer macht und letztendlich das Dienstangebot insgesamt einschränkt. Cloud-Computing wird dabei in Zukunft eine wichtige Rolle spielen.
Die Dissertation beschäftigt sich daher mit dem Problem IoT-Gerätedaten an IoT-Clouds plattformübergreifend und anbieterübergreifend nutzbar zu machen. Die Motivation und die adressierte Forschungslücke zeigen die Notwendigkeit der Beschäftigung mit dem Thema auf. Ausgehend davon, wird das Konzept einer dezentral organisierten IoT-Intercloud vorgeschlagen, welches in der Lage ist heterogene IoT-Clouds zu integrieren. Die Analyse des Standes der Technik zeigt, das IoT-Clouds genügend Eigenschaften teilen, um in Zukunft eine Adaption zu einer einheitlichen Schnittstelle für die IoT-Intercloud zu schaffen. Das Konzept umfasst zunächst die Komponentenarchitektur eines Intercloud-Brokers zur Etablierung einer IoT-Intercloud. Ausgehend davon wird in vertiefenden Teilkonzepten ein Discovery-Service zum Finden von Gerätedaten und einem Push-Stream-Provider, für die Zustellung von IoT-Event-Notifications in Echtzeit, behandelt. Eine Evaluation zeigt letztlich die praxistaugliche Realisierbarkeit, Skalierbarkeit und Performance der Konzeption und des implementierten Prototyps.

MCC (Mobile Cloud Computing) est un candidat très fort pour le NGN (Next Generation Network) qui permet aux utilisateurs mobiles d’avoir une mobilité étendue, une continuité de service et des performances supérieures. Les utilisateurs peuvent s’attendre à exécuter leurs travaux plus rapidement, avec une faible consommation de batterie et à des prix abordables ; mais ce n’est pas toujours le cas. Diverses applications mobiles ont été développées pour tirer parti de cette nouvelle technologie, mais chacune de ces applications possède ses propres exigences. Plusieurs MCA (Mobile Cloud Architectures) ont été proposées, mais aucune n'a été adaptée pour toutes les applications mobiles, ce qui a mené à une faible satisfaction du client. De plus, l'absence d'un modèle d'affaires (business model) valide pour motiver les investisseurs a empêché son déploiement à l'échelle de production. Cette thèse propose une nouvelle architecture de MCA (Mobile Cloud Architecture) qui positionne l'opérateur de téléphonie mobile au cœur de cette technologie avec un modèle d'affaires de recettes. Cette architecture, nommée OCMCA (Operator Centric Mobile Cloud Architecture), relie l'utilisateur d’un côté et le fournisseur de services Cloud (CSP) de l'autre côté, et héberge un cloud dans son réseau. La connexion OCMCA / utilisateur peut utiliser les canaux multiplex menant à un service beaucoup moins cher pour les utilisateurs, mais avec plus de revenus, et de réduire les embouteillages et les taux de rejet pour l'opérateur. La connexion OCMCA / CSP est basée sur la fédération, ainsi un utilisateur qui a été enregistré avec n’importe quel CSP, peut demander que son environnement soit déchargé de cloud hébergé par l'opérateur de téléphonie mobile afin de recevoir tous les services et les avantages de OCMCA.Les contributions de cette thèse sont multiples. Premièrement, nous proposons OCMCA et nous prouvons qu'il a un rendement supérieur à toutes les autres MCA (Mobile Cloud Architectures). Le modèle d'affaires (business model) de cette architecture se concentre sur la liberté de l'abonnement de l'utilisateur, l'utilisateur peut ainsi être abonné à un fournisseur de cloud et être toujours en mesure de se connecter via cette architecture à son environnement à l'aide du déchargement et de la fédérationMobile cloud computing is a very strong candidate for the title "Next Generation Network" which empowers mobile users with extended mobility, service continuity and superior performance. Users can expect to execute their jobs faster, with lower battery consumption and affordable prices; however this is not always the case. Various mobile applications have been developed to take advantage of this new technology, but each application has its own requirements. Several mobile cloud architectures have been proposed but none was suitable for all mobile applications which resulted in lower customer satisfaction. In addition to that, the absence of a valid business model to motivate investors hindered its deployment on production scale. This dissertation proposes a new mobile cloud architecture which positions the mobile operator at the core of this technology equipped with a revenue-making business model. This architecture, named OCMCA (Operator Centric Mobile Cloud Architecture), connects the user from one side and the Cloud Service Provider (CSP) from the other and hosts a cloud within its network. The OCMCA/user connection can utilize multicast channels leading to a much cheaper service for the users and more revenues, lower congestion and rejection rates for the operator. The OCMCA/CSP connection is based on federation, thus a user who has been registered with any CSP, can request her environment to be offloaded to the mobile operator's hosted cloud in order to receive all OCMCA's services and benefits

It was clear that the Cloud would change the way we develop, manage and use information systems. However, the adoption and popularization of Cloud were slow and difficult given the youth of the concepts and heterogeneity of the existing solutions. This difficulty in adoption is reflected by the lack of standard, the presence of heterogeneous architectures and APIs, the introduction of Vendor Lock-In imposed by the market leaders and the lack of cloud federation principles and facilitators. The main motivation for our PhD is to simplify the adoption of the cloud paradigm and the migration to cloud environments and technologies. Our goal has consequently been to improve interoperability and enable federation in the cloud. The thesis focused on two main areas. The first concerns the convergence of future networks and clouds and the second the improvement of federation and interoperability between heterogeneous cloud solutions and services. Based on our work in state of the art about Cloud Computing and Cloud Networking, we defined in this thesis two architectures for Cloud federation. The first architecture enables the merging (convergence) of Cloud Computing and Cloud Networking. The second architecture addresses interoperability between services and proposes cloud-brokering solutions. The study enabled the identification of two essential components for cloud federation, namely: a generic interface and a message exchange system. These two components have been two contributions of our thesis. The proposed federation architectures and these two components summarize the four major contributions of our work

Full textAbstract:
Cloud computing brought flexibility, scalability, and capital cost savings to the IT industry. As more companies turn to cloud solutions, securing cloud based services becomes increasingly important, because for many organizations, the final barrier to adopting cloud computing is whether it is sufficiently secure.More users rely on cloud storage as it is mainly because cloud storage is available to be used by multiple devices (e.g. smart phones, tablets, notebooks, etc.) at the same time. These services often offer adequate protection to user's private data. However, there were cases where user's private data was accessible to other user's, since this data is stored in a multi-tenant environment. These incidents reduce the trust of cloud storage service providers, hence there is a need to securely migrate data from one cloud storage provider to another.This thesis proposes a design of a service for providing Security as a Service for cloud brokers in a federated cloud. This scheme allows customers to securely migrate from one provider to another. To enable the design of this scheme, possible security and privacy risks of a cloud storage service were analysed and identified. Moreover, in order to successfully protect private data, data protection requirements (for data retention, sanitization, and processing) were analysed. The proposed service scheme utilizes various encryption techniques and also includes identity and key management mechanisms, such as "federated identity management".While our proposed design meets most of the defined security and privacy requirements, it is still unknown how to properly handle data sanitization, to meet data protection requirements, and provide users data recovery capabilities (backups, versioning, etc.).

Full textAbstract:
AbstractContainerization technology helps achieving not only better portability and interoperability but also better performance and efficiency on various cloud computing arrangements. Such technology is expected to empower cloud federations by enhancing portability and scalability across the federation. In this paper, we propose an architecture by adding two subcomponents to the NIST reference architecture for identifying resources and managing container orchestration in cloud federation environments. The architecture adds two subcomponents to the NIST reference architecture. The proposed two new sub-components enable resource identification and container orchestration across cloud federation members. These names of the two subcomponents are the Resource Identifier and the Container Orchestrator, respectively. The Resource Identifier component identifies the appropriate federated member for allocating tasks based on previous experience and current status. The Container Orchestrator facilitates the management and orchestration of containers at the federation level. We also identified several techniques, which can be used for resource identification. Among those, linear regression technique is selected for resource provisioning and identification of federation members. Further, these techniques are also expected to learn from log files from previous executions and prioritize resources based on the current resource status and previous experience.

AbstractA cloud federation (CF) is an alliance of cloud service providers (CSPs) working together to overcome scalability and portability barriers. However, there are some business challenges (e.g., lack of trust, lack of schemes for revenue sharing, and lack of schemes for resource sharing) and technological challenges (e.g., missing schemes for resource provisioning, lack of coordinated resource management, and little load balancing), causing instability in CFs. As CF alliances pursue strategic goals, they require intensive knowledge sharing. In fact, practitioners have confirmed a positive impact of knowledge management on stability and success of strategic alliances (SA). According to the literature, SAs may also face learning issues such as non–controlled information revelation or unbalanced dissemination of core competencies. These findings pose challenges about the nature of the knowledge and how to share it within a CF. Nonetheless, there is only scarce literature on KM in CF. Thus, the purpose of the paper is to propose a KM framework for CFs with the aim of strengthening stability and potential CF commercialization.

Full textAbstract:
Pedagogical modeling of modern educational environments remains an urgent task of educational sciences. Research on the formation and development of digital competence of specialists, although they have common features, differ and acquire characteristic features depending on the field of application. This is due to the focus on mastering specific professional skills and increasing the professional level. We found out that, compared to the social and humanitarian sphere and medicine, the development of digital competence of specialists in the military and defense industry is little discussed in scientific sources. The development of digital competence of military personnel, in particular military management officers, is an urgent problem that requires an immediate solution. On the one hand, the armed aggression of the Russian Federation adds to the criticality of the situation, on the other hand, scientific and technical progress and, as a result, the appearance of new types of weapons and the complexity of digital tools in the environments of military specialists. Scientific approaches and conceptual principles regarding the formation of digital competence of the Armed Forces of Ukraine and NATO member countries are described. Problems, contradictions and trends in the development of digital education of military specialists in the system of professional development are singled out. The article clarifies the concept of “digital competence of military command officers” of the Armed Forces of Ukraine. The authors developed and substantiated a theoretical model of a computer-oriented methodical system for the development of digital competence of officers of the military administration of the Armed Forces of Ukraine in the system of professional development, which is presented in an informative scheme with a description of individual modules combined into conceptual, target, content-methodical, procedural, technological and effective blocks. The built model ensures systematicity and consistency of the educational process in the digital educational environment of higher military education institutions for the development of digital competencies of military management officers. The technological unit contains a variety of software for training and training. In particular, specialized computer programs and multimedia guides. In the content-methodical block, among other things, the following modules are presented: cloud services; information-didactic and educational-methodical learning tools, multimedia objects, VR/AR tools, AI elements that allow selection of existing ones or creation of new learning materials; Training Course; diagnostic tools, etc. The prospect is the verification of the developed model during distance training.
