QoS in Self-healing Web Services September 1st, 2008 Milano, Italy

http://qsws08.dei.polimi.it

in conjunction with BPM 2008 6th International Conference on Business Process Management September 1-4 2008 Milano, Italy http://emma.polimi.it/emma/showEvent.do?page=303&idEvent=22

Background and motivation

The development of composite services poses very interesting challenges concerning their Quality of Service (QoS) characteristics. On the one hand, a composite Web Service depends on the QoS properties of its own Web Service suppliers in order to provide a satisfactory service to the user. On the other hand, the main issues for the fulfillment of QoS and service level agreements are concerned with Web service performance variability. Indeed, the QoS of a Web Service may evolve relatively frequently, either because of internal changes or because of workload fluctuations. The performance of the composite Web service may be significantly improved by monitoring the execution of the component Web Services and by flexibly reacting to faults and anomalies in a timely fashion.

The concept of self-healing Web Service has been introduced in order to describe services which exhibit such properties. A self-healing Web Service can repair itself if any execution problems occur, in order to successfully complete its own execution, while respecting QoS agreements. In the design of a self-healing WS, several aspects have to be considered. For instance, the service should be able to detect failures as soon as possible and to enact suitable recovery actions. Moreover, different QoS service levels might be considered in order to complete the service execution in case of error, possibly with degraded performance.

********** Call for papers ************

For this workshop, we will consider contributions devoted to Web Services, QoS management, diagnosis and autonomic services. Specifically, the relevant topics include, but are not limited to:

* Distributed and centralized solutions for the diagnosis and repair of choreographed and/or orchestrated Web Services * Design for the diagnosability and repairability of Web Services * QoS management in choreographed and/or orchestrated Web Services * Monitoring simple and composite Web Services * Ontologies for QoS * Dynamic reconfiguration of Web Services * Predictive QoS management for Web Services * Autonomic services

Workshop format

The goal of this workshop is to bring together researchers and practitioners, both from the Academia and from the Industry, working in the areas of Web Service composition, QoS management and diagnosis, who investigate concepts, methods, techniques, and tools to design and manage self-healing Web Services.

All contributions will be made available in a Web site before the main conference, so that participants can read them in advance. Morever, a CD including the contributions and pre-proceedings will be distributed at the conference. After the workshop, post-proceedings will be prepared and published in a volume edited by Springer (the post-proceedings will include the papers presented at all the BPM 2008 workshops and reviewed on the basis of the discussion).

Moreover, the best paper of each workshop will be invited to a special issue of the "Software Process Improvement and Practice" Journal: best papers will undergo a further peer revision process in order to select the subset to be published in the special issue.

Important Dates: o Paper submission deadline: 6 June 2008 o Notification of acceptance: 27 June 2008 o Camera ready: 5 July 2008 o Workshop day: 1 September 2008 o Post-proceeding version of the paper: 23 September 2008

Submission instructions:

The following types of submission are solicited: * Long paper submissions, describing substantial contributions of novel ongoing work. Long papers should be at most 12 pages long. * Short paper submissions, describing work in progress. These papers should be at most 6 pages long. * There is no possibility to buy additional pages.

All the submissions should be formatted as follows: * The first page should include the title, author's name(s), affiliation, mailing address, e-mail, the abstract of the paper and up to five keywords. * Papers should be submitted in the new Springer LNBIP format: Suitable templates can be retrieved from the LNCS Web site at the following URL: http://www.springer.com/computer/lncs?SGWID=0-164-7-487211-0. * Papers should be submitted exclusively as PDF files.
