Enhanced Deployment Process for QoS-aware Services

Authors:

Keywords: Service-oriented architecture; QoS-aware service; Deployment.

Abstract:
Service-oriented architectures (SOA) are a widely used design paradigm for the creation and integration of distributed enterprise applications. The predominant technology used for implementation are Web services. In the business domain, Web Services must be equipped with quality of service (QoS) attributes, like, e.g., security, performance, etc. WS-Policy standard provides a generic framework to formally describe QoS. Verification and enforcement of such formally described QoS require corresponding QoS modules, e.g., handlers, to be installed at the runtime environment. In this work, we provide an approach that enhances the current deployment process for Web services. The aim is to provide a sophisticated process that not only deploys Web Services and formal QoS descriptions, but to guarantee that the desired QoS are verified and enforced in the runtime environment. We therefore introduce additional steps for the analysis of WS-Policy descriptions, the identification of corresponding handlers, and their installation at the runtime environment. As a result, a comprehensive, automated deployment process is created, and the fulfillment of an overall WS-Policy description is ensured.
