Conception et évaluation de performance d'un Bus applicatif, massivement parallèle et orienté service / Design and Performance Evaluation of a Massively Parallel Service-Oriented BusBenosman, Ridha Mohammed 12 December 2013 (has links)
Enterprise Service Bus (ESB) est actuellement l'approche la plus prometteuse pour l'implémentation d'une architecture orientée services (SOA : Service-Oriented Architecture) par l'intégration des différentes applications isolées dans une plateforme centralisée. De nombreuses solutions d'intégration à base d'ESB on été proposées, elles sont soit open-source comme : Mule, Petals, ou encore Fuse, soit propriétaires tels que : Sonic ESB, IBM WebSphere Message Broker, ou Oracle ESB. Cependant, il n'en existe aucune en mesure de traiter, à la fois des aspects : d'intégration et de traitement massivement parallèle, du moins à notre connaissance. L'intégration du parallélisme dans le traitement est un moyen de tirer profit des technologies multicœurs/multiprocesseurs qui améliorent considérablement les performances des ESBs.Toutefois, cette intégration est une démarche complexe et soulève des problèmes à plusieurs niveaux : communication, synchronisation, partage de données, etc.Dans cette thèse, nous présentons l'étude d'une nouvelle architecture massivement parallèle de type ESB. / Enterprise service bus (ESB) is currently the most promising approach for business application integration in distributed and heterogeneous environments. It allows to deploy a service-oriented architecture (SOA) by the integration of all the isolated applications on a decentralized platform.Several commercial or open source ESB-based solutions have been proposed. However, to the best of our knowledge, none of these solutions has integrated the parallel processing. The integration of parallelism in the treatment allows to take advantage of the multicore/multiprocessor technologies and thus can improve greatly the ESB performance. However, this integration is difficult to achieve, and poses problems at multiple levels (communication, synchronization, etc). In this study, we present a new massively parallel ESB architecture that meets this challenge.

Open Source Enterprise Service Bus : Analyzing impact and value in a large organizationBagherinia, Sharareh January 2013 (has links)
System integration is a challenging task for large organizations since they must manage complex IT infrastructures, and utilize hundreds of applications that cause a myriad of complications as a result of rapidly evolving systems and technologies. Over time customer requirements and the automation of internal business functions forced the gigantic service providers to develop and buy applications for different purposes. Not many years before, the applications in an organization were usually separated silos, specifically designed to answer a particular problem. However, this way of working was not efficient. It is not impossible to design one application that runs the total business, however, in reality it can't respond to all the needs inside an organization. In most cases the applications need to interact with each other and to reuse functionalities or data. At this point the concept of integrating systems first came to existence.The progress in computer science and information technology has also affected the way that integration between applications was developed and designed over the years. This shows that there's always some new method that should be studied and investigated. In recent years, the Enterprise Service Bus has come to the market and there are many vendors in the market claiming that they have produced the exact solution needed for requirements of organizations.In this work, the attempt was to construct an understanding of the Enterprise Application Integration practices and methods which have been utilized over the years. Mixed methods research a combination of interviews and questionnaire, and Design Science Research methods were used to generate empirical results. While the first two methods was used to supply the input for challenges of system integration, the DSR build and evaluate method was employed to test the ESB product. The criteria for the test were developed mostly as the outcome of interviews and the questionnaire as the main challenge. The aim was to verify efficiency and effectiveness of the selected and proposed ESB under special designed DSR build and evaluate phases.As a result of both theoretical and empirical studies in combination with selection of different methods in Information System research, the work presents a knowledge foundation for organizations with the aim to make a change in their current system integration practices and patterns utilizing approaches facilitated by ESB products.

A service orientated architecture and wireless sensor network approach applied to the measurement and visualisation of a micro injection moulding process. Design, development and testing of an ESB based micro injection moulding platform using Google Gadgets and business processes for the integration of disparate hardware systems on the factory shop floorRaza, Umar January 2014 (has links)
Factory shop floors of the future will see a significant increase in interconnected devices for monitoring and control. However, if a Service Orientated Architecture (SOA) is implemented on all such devices then this will result in a large number of permutations of services and composite services. These services combined with other business level components can pose a huge challenge to manage as it is often difficult to keep an overview of all the devices, equipment and services. This thesis proposes an SOA based novel assimilation architecture for integrating disparate industrial hardware based processes and business processes of an enterprise in particular the plastics machinery environment. The key benefits of the proposed architecture are the reduction of complexity when integrating disparate hardware platforms; managing the associated services as well as allowing the Micro Injection Moulding (µIM) process to be monitored on the web through service and data integration. An Enterprise Service Bus (ESB) based middleware layer integrates the Wireless Sensor Network (WSN) based environmental and simulated machine process systems with frontend Google Gadgets (GGs) based web visualisation applications. A business process framework is proposed to manage and orchestrate the resulting services from the architecture.
Results from the analysis of the WSN kits in terms of their usability and reliability showed that the Jennic WSN was easy to setup and had a reliable communication link in the polymer industrial environment with the PER being below 0.5%. The prototype Jennic WSN based µIM process monitoring system had limitations when monitoring high-resolution machine data, therefore a novel hybrid integration architecture was proposed. The assimilation architecture was implemented on a distributed server based test bed. Results from test scenarios showed that the architecture was highly scalable and could potentially allow a large number of disparate sensor based hardware systems and services to be hosted, managed, visualised and linked to form a cohesive business process.

Cilia : un framework pour le développement d'applications de médiation autonomiquesMorand, Denis 05 November 2013 (has links) (PDF)
Cette thèse se situe dans le domaine de l'informatique orientée service. Elle propose un ESB (Enterprise Service Bus) autonomique, c'est-à-dire capable de s'autogérer sur un ensemble d'aspects. Cet ESB, nommé Cilia autonomique, permet de construire des applications de médiation sensibles au contexte. Précisément, la version autonomique de Cilia, que nous proposons, permet l'optimisation de l'utilisation des ressources de la plate-forme d'exécution et l'adaptation dynamique des chaînes de médiation au niveau de la configuration et de la topologie. Notre framework permet également de présenter à tout moment un modèle simplifié des phénomènes liés à l'exécution des chaînes et, ainsi, de faciliter le raisonnement et la prise de décisions d'adaptation. Les travaux de cette thèse ont été validés dans le cadre de l'informatique pervasive. En particulier, Cilia autonomique a été utilisé et instrumenté pour la mise en œuvre d'applications de maintien à domicile et de suivi de la santé des usagers. Les résultats sont disponibles en open source.
