Towards robustness and self-organization of ESB-based solutions using service life-cycle management

Enterprise Service Bus (ESB) is a middleware infra-structure that provides a way to integrate loosely-coupled heterogeneous software applications based on the Service Oriented Architecture principles. The life-cycle management of services in such highly changing environments is a critical issue for the component’s reuse, maintenance and operation. This work introduces a service life-cycle management module that extends the traditional functionalities with advanced monitoring and data analytics to contribute for the robustness and self-organization of networks of clusters based on ESB platforms. The realization of this module was embedded in the JBoss ESB, considering a sniffer mechanism to collect relevant details of the service messages crossing the bus. A Liferay portal was created to display information related to the services’ health.Um Barramento de Serviços (BS) é um middleware que oferece uma infraestrutura que permite a integração de aplicações heterogéneas, com base nos princípios das Arquiteturas Orientadas aos Serviços. A gestão do ciclo de vida dos serviços em tais ambientes altamente dinâmicos é um problema crítico com impacto na operação e manutenção do sistema, bem como na capacidade de reutilização de componentes. Este trabalho apresenta um módulo de gestão do ciclo de vida de serviços, que acrescenta às funcionalidades tradicionais a monitorização avançada e a análise de dados, no sentido de contribuir para a robustez e auto-organização de redes de agregados computacionais baseados em plataformas BS. O módulo foi integrado no JBoss ESB e utilizou-se um sniffer para recolher os detalhes das mensagens que se encontram a ser trocadas no barramento. Foi criado um portal Liferay para apresentar a informação relativa à saúde dos serviços.This work was supported by the European Union FP7 Programme under the ARUM project No. 31405

Fog computing pour l'intégration d'agents et de services Web dans un middleware réflexif autonome

International audienceService Oriented Architecture (SOA) has emerged as a dominant architecture for interoperability between applications, by using a weak-coupled model based on the flexibility provided by Web Services, which has led to a wide range of applications, what is known as cloud computing. On the other hand, Multi-Agent System (MAS) is widely used in the industry, because it provides an appropriate solution to complex problems, in a proactive and intelligent way. Specifically, Intelligent Environments (Smart City, Smart Classroom, Cyber Physical System, and Smart Factory, among others) obtain great benefits by using both architectures, because MAS endows intelligence to the environment, while SOA enables users to interact with cloud services, which improve the capabilities of the devices deployed in the environment. Additionally, the fog computing paradigm extends the cloud computing paradigm to be closer to the things that produce and act on the intelligent environment, allowing to deal with issues like mobility, real time, low latency, geo-localization, among other aspects. In this sense, in this article we present a middleware, which not only is capable of allowing MAS and SOA to communicate in a bidirectional and transparent way, but also, it uses the fog computing paradigm autonomously, according to the context and to the system load factor. Additionally, we analyze the performance of the incorporation of the fog-computing paradigm in our middleware and compare it with other works
