It is my great pleasure to welcome you to the second issue of the IEEE Transactions on Services Computing in 2011. In the services and software industry, Services Computing has become a foundational discipline for many emerging technologies such as cloud computing and social networking. In this issue, I am pleased to publish seven research papers with a theme on Quality-Driven Service and Workflow Management, which deal with several aspects of management of services systems that include dependability, security, performance, and transaction management.
The first paper is entitled “Addressing Dependability throughout the SOA Life Cycle” by Vladimir Stantchev and Miroslaw Malek. The authors formalize the service dependability issue as an SLA-based optimization problem in the context of the entire SOA life cycle.
The second paper is entitled “Expressive and Deployable Access Control in Open Web Service Applications” by Claudio A. Ardagna, Sabrina De Capitani di Vimercati, Stefano Paraboschi, Eros Pedrini, Pierangela Samarati, and Mario Verdicchio. Toward granting access control in the open service world, the authors propose a formal model that conforms with the XACML standard. A dialog management framework is also presented to enable access control interactions between services.
The third paper is entitled “Automatic (Re)Configuration of IT Systems for Dependability” by Marco Domenico Aime, Antonio Lioy, and Paolo C. Pomi. This paper presents a model-driven configuration and reconfiguration approach for IT systems to ensure ontology-specified dependability properties.
The fourth paper is entitled “Robust Execution of Service Workflows Using Redundancy and Advance Reservations” by Sebastian Stein, Terry R. Payne, and Nicholas R. Jennings. The authors present an algorithm that balances SLA, redundancy, and reservation of comprising services to satisfy time-critical workflow requirements.
The fifth paper is entitled “QoS-Aware Web Service Recommendation by Collaborative Filtering” by Zibin Zheng, Hao Ma, Michael R. Lyu, and Irwin King. By leveraging past usage experiences of service consumers, the authors present a collaborative filtering approach for predicting QoS values of web services thus providing service recommendations.
The sixth paper is entitled “A Formal Approach Enabling Risk-Aware Business Process Modeling and Simulation” by Simon Tjoa, Stefan Jakoubi, Gernot Goluch, Gerhard Kitzler, Sigrun Goluch, and Gerald Quirchmayr. Taking into consideration both economic and security aspects, this paper proposes a formal model to express relations between threats, detection mechanisms, safeguards, recovery measures, and their effects on business processes.
The seventh paper is entitled “Transaction Management in Service-Oriented Systems: Requirements and a Proposal” by Chang-ai Sun, Elie el Khoury, and Marco Aiello. The authors propose a semi-automatic approach that implements transaction management within service composition processes by integrating BPEL specifications and web service coordination protocols.
I hope you like this issue of TSC. I also want to encourage all of you to continuously contribute to TSC as authors, volunteers/reviewers, and promoters. Without support from you, it is unlikely to run TSC with such great success. I would like to send my special thanks to all the reviewers.
