Towards a Service Governance Framework for the Internet of Services

In: Proceedings of the 17th European Conference on Information Systems, ECIS 2009

Category: Proceedings

Abstract

Companies nowadays face constantly changing market conditions, new competitive threats, and new legal regulations. Service-oriented Architectures (SOA) provide a promising way to address these challenges at the level of the company’s IT infrastructure. The paradigm of the Internet of Services envisions trade on a global service-enabled internet. Governance frameworks have been introduced to guideline an enterprise’s organisation and IT and ensure smooth operations. More specifically, IT Governance and recently SOA Governance have been established. The basic structure of IT governance frameworks is applicable to SOA. However, they lack functionality or applicability concerning SOA-specific challenges. Current approaches that focus mere SOA Governance lack framework scope. The issue aggravates taking into account the current shift to a marketplace-like Internet of Services. We identify these issues and provide initial insights on building blocks for a Service Governance Framework that enables operations for companies in a brokered service network. We discuss service lifecycle phases, stakeholder roles, and management processes taking into consideration existing frameworks such as ITIL and CObIT as well as industry-specific approaches from companies such as SAP, Oracle, and HP.

Governance of a Service-Oriented Architecture for Environmental and Public Security

In: Information Technologies in Environmental Engineering, ITEE 2009 - Fourth International ICSC Symposium; Springer, Berlin Heidelberg New York

Category: Proceedings

Abstract

Research for the application of technical support in environmental projects has grown rapidly due to the progress of sensor network systems and the large, scalable IT infrastructures that can unify and expand them. There are numerous attempts to make use of new technologies in order to serve environmental purposes. The research presented in this paper focuses on critical aspects of the core infrastructure of a project that aims to serve these purposes as well. The nature of the actions that must be taken against environmental disasters, which are our target use cases, dictate that extended, cross-organizational information and communication systems are engaged. In order to integrate information from different sources and process heterogeneous services, the IT infrastructure is based on the paradigm of Service-Oriented Architectures (SOA). However, the distributed and often very large nature of an SOA leads to a need for governance mechanisms. We present an SOA governance approach targeted to serve the purposes of large-scale distributed IT landscapes for environmental and public security.

On distributed SLA monitoring and enforcement in service-oriented systems

In: International Journal On Advances in Systems and Measurements, Vol. 2, No. 1

Category: Publications in scientific journals

Abstract

For the integration of systems across enterprise boundaries, the application of Web service technology and the Service-oriented Architecture (SOA) paradigm have become state of the art. Here, the management of the quality delivered by third party services is crucial. In order to achieve high service quality, requirements therefore need to be initially specified using Service Level Agreements (SLAs), which are later on monitored during runtime. In case of SLA violations, appropriate countermeasures have to be executed. The paper presents an integrated approach for SLA monitoring and enforcement using distributed autonomous monitoring units. Additionally, the paper presents strategies to distribute those units in an existing service-oriented infrastructure based on mixed integer programming techniques. Furthermore, appropriate framework support is given by the AMAS.KOM framework enabling distributed SLA monitoring and enforcement based on the developed distribution strategies. As a foundation for our approach, the WS-Re2Policy language is presented, which allows the specification of both requirements with respect to service quality and the necessary countermeasures at the same time.

Qualitative and Quantitative Aspects of Cooperation Mechanisms for Monitoring in Service-oriented Architectures

In: Proceedings of the Third IEEE International Conference on Digital Ecosystems and Technologies (IEEE DEST 2009)

Category: Proceedings

Abstract

Cooperation mechanisms for agents monitoring service-based workflows are a means to address the increasing complexity of modern enterprise architectures. These mechanisms are inspired by existing biological mechanisms and extend an existing decentralized monitoring architecture in order to handle deviations from Service Level Agreements autono-mously. As the core cooperation mechanisms have been subject of our previous work and have been described in detail earlier, we present now an evaluation of our concepts regarding both effectiveness and efficiency, based on an implemented proto-type.

SOA Governance: Survey and Model

In: Proceedings of pre-ICIS SIG SRV workshop; Special Interest Group Services

Category: Proceedings

Abstract

Governance for Service-oriented Architectures (SOA) is an upcoming research topic. It faces a multitude of new challenges when compared to the related concept IT Governance. So far, a variety of special frameworks for SOA Governance have been proposed. Until now, there is no holistic approach covering all perspectives and consolidating them to form a universally valid model. During our research, we analyzed several approaches to SOA Governance, identified major components, and developed a generic governance model for SOA.
