The main goal of the International Workshop on Performance Assessment and Auditing in Service Computing (PAASC) was to bring together researchers and industry representatives, providing them the opportunity to present research and development results, discus lessons learned (e.g., from designing, building and using services), and advance novel ideas on topics in the area of performance assessment...
Whilst monitoring web services provides benefits in terms of demonstrating that Service Level Agreements (SLAs) have been met, monitoring comes with a cost on the QoS of delivered services. We present the application of our method for optimizing the configuration of a suite of web service monitors in order to minimise the QoS impacts of monitoring on a web service provider. We discuss the actions...
As service-oriented systems grow larger and more complex, so does the challenge of configuring the underlying hardware infrastructure on which their consitituent services are deployed. With more configuration options (virtualized systems, cloud-based systems, etc.), the challenge grows more difficult. Configuring service-oriented systems involves balancing a competing set of priorities and choosing...
Today’s business environment demands a high rate of compliance of service-enabled business processes with which enterprises are required to cope. Thus, a comprehensive compliance management framework is required such that compliance management must crosscut all the stages of the complete business process lifecycle, starting from the very early stages of business process design. Formalizing compliance...
Architecting applications for the Cloud is challenging due to significant differences between traditional hosting and Cloud infrastructure setup, unknown and unproven Cloud performance and scalability characteristics, as well as variable quota limitations. Building workable cloud applications therefore requires in-depth insight into the architectural and performance characteristics of each cloud offering,...
Enterprises increasingly choose to focus on core competences and often outsource different services in order to achieve set goals. Although extensive research and development work is pursued on service computing, the main focus is on technical aspects. Business and economic issues in the context of service computing receive little attention. The scope of this article is to present preliminary results...
The first international workshop on Services, Energy, and Ecosystem (SEE 2010) focused on creating sustainable (green) energy-efficient services and fostering the growth towards a new eco-friendly world of services. Technical papers of high quality have been submitted, of which six were accepted (with a 60% of acceptance rate). Moreover, a keynote given by Professor Barbara Pernici presented an overview...
This paper proposes the development of a management controller, which balances the service center servers’ workload and hardware resources usage to locally optimize energy consumption. The controller exploits energy saving opportunities due to short-term fluctuations in the performance request levels of the server running tasks. The paper proposes Dynamic Power Management strategies for processor...
In this paper we propose the development of an Energy Aware Context Model for representing the service centre energy/performance related data in a uniform and machine interpretable manner. The model is instantiated at run-time with the service center energy/performance data collected by monitoring tools. Energy awareness is achieved by using reasoning processes on the model instance ontology representation...
Carbon emission of IT is an issue. ICT energy consumption is expected to grow by 73% (instead of the originally targeted 26%) until 2020, and the service sector alone counts for 70% of the European economy. Energy consumption is a combination of what we use, and how we use it. Most green initiatives look at what types of devices do consume energy, and try to optimize their up-time as such. Few initiatives,...
Information and communication technology has experienced a vast development and increased usage over the past few years. This development again yields to increasing energy consumption. In this paper we provide a research agenda that picks up this serious development and suggests first approaches how holistic energy efficiency could be introduced in enterprises without neglecting a company’s performance...
A key element of any approach to meeting the climate change challenge is the ability to improve operational efficiency in a pervasive fashion. The notion of a business process is a particularly useful unit of analysis in this context. In the Abnoba framework, we enable business process management (and in particular, business process design/re-design) with explicit support for the environmental sustainability...
The energy sector, which has traditionally been an oligarchic closed one, is undergoing major changes at all levels: more and more players are authorized to produce, deal and transport energy, and energy consumers are now in the position to also produce and trade energy. This new trend can be supported by Service-Oriented Architectures (SOAs) at all levels. In this short position paper, we overview...
The purpose of the SOC-LOG workshop was to present and discuss recent significant developments at the intersection of service-oriented computing and logistics systems/supply chain management, and to promote cross-fertilization and exchange of ideas and techniques between these fields. The relation to ICSOC 2010 is that, on one hand, the conference addresses the core concepts such as interacting business...
In this manuscript, we discuss the need for, and present a new system architecture for cross collaboration among multiple service enterprises. We demonstrate the importance and inevitability of such collaboration along with challenges in its proper realization through several real-life examples taken from different business domains. We then show that these challenge are rooted in two key factors:...
In logistics, as in many other business sectors, service-oriented architectures (SOAs) are offering the possibility for applications to interact with each other across languages and platforms, and for external services to be procured automatically through dedicated middleware components. In this setting, one of the critical business aspects that need to be supported is the negotiation of non-functional...
