  • Conference Proceeding: A Model for Enabling Context-Adapted Deployment and Configuration Operations for the Banking Environment

    [show abstract] [hide abstract]
    ABSTRACT: In the banking sector business requirements continuously change whereas IT infrastructure investments must be amortized over years. This conflict produces very heterogeneous systems. Adopting the SOA / BPM approach helps coping with that complexity. This way, everything is a service, easing composition and integration. On top of that, strict security and reliability requirements exacerbate the need of a robust management infrastructure. We propose a service-centric operational management architecture for which we have defined a resource model based on the leading standards for characterizing systems, services and operations. This model is supported by a dynamic agent infrastructure, which automatically instruments the targeted environments. These concepts are illustrated by a proof of concept consisting of deployment and configuration activities over distributed banking services.

  • Conference Proceeding: A Case Study on Software Evolution towards Service-Oriented Architecture
    F. Cuadrado, B. Garcia, J.C. Dueas, H.A. Parada
    [show abstract] [hide abstract]
    ABSTRACT: The evolution of any software product over its lifetime is unavoidable, caused both by bugs to be fixed and by new requirements appearing in the later stages of the product's lifecycle. Traditional development and architecture paradigms have proven to be not suited for these continual changes, resulting in large maintenance costs. This has caused the rise of approaches such as Service Oriented Architectures (SOA), based on loosely coupled, interoperable services, aiming to address these issues. This paper describes a case study of the evolution of an existing legacy system towards a more maintainable SOA. The proposed process includes the recovery of the legacy system architecture, as a first step to define the specific evolution plan to be executed and validated. The case study has been applied to a medical imaging system, evolving it into a service model.
