    An approach for the management of service-oriented architecture (SoA) based application systems
    (Enterprise modelling and information systems architectures, 2005) Berbner, Rainer; Grollius, Tobias; Repp, Nicolas; Heckmann, Oliver; Ortner, Erich; Steinmetz, Ralf
    Flexible business processes are a key success factor for enterprises to succeed in globalised markets. The Service-oriented Architecture (SoA) concept is very well suited to support flexible business processes and application systems because capabilities (in form of services) can be composed in the most efficient way to achieve a high level of agility. However, the management of SoA-founded application systems is often neglected. Thus, we present an approach that enhances the traditional SoA concept by additional management functionality, e.g. monitoring mechanisms and SLA management. As a validation of our concept we introduce WSQoSX, a prototypical implementation based on Web Services.

    Eine Dienstgüte unterstützende Webservice-Architektur für flexible Geschäftsprozesse
    (Wirtschaftsinformatik: Vol. 47, No. 4, 2005) Berbner, Rainer; Heckmann, Oliver; Mauthe, Andreas; Steinmetz, Ralf
    Web services as a technology to enable distributed business processes gain in importance. However, the support of Quality of Service (QoS) is crucial in this context. Thus, we present an integrated web service architecture with comprehensive QoS support. The architecture we introduce in this paper supports the assessment of web services to assure that only web services will be used in critical business processes that satisfy the requirements defined by the user. The selection and execution of a certain web service depends on its QoS-properties that must be guaranteed in Service Level Agreements (SLAs). The compliance with SLAs is monitored by the system as well. Furthermore we introduce a prototypical implementation of our web service architecture.

    Management of Service-oriented Architecture (SoA)-based Application Systems
    (Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 2, Nr. 1, 2007) Berbner, Rainer; Grollius, Tobias; Repp, Nicolas; Eckert, Julian; Heckmann, Oliver; Ortner, Erich; Steinmetz, Ralf
    Flexible business processes are a key success factor for enterprises to succeed in globalized markets. The Service-oriented Architecture (SoA) concept is very well suited to support flexible business processes and their underlying application systems because services can be composed in an efficient way to achieve a high level of agility. However, the management of SoA-founded application systems is often neglected. Thus, in this paper we conclude and extend our previous work on the enhancement of the generic SoA-based concept by additional management functionality, e.g. monitoring mechanisms and SLA management. As a validation of our concept we introduce WSQoSX, a prototypical implementation based on Web Services.
