PAASC 2011 - 2nd International Workshop on Performance Assessment and Auditing in Service Computing 2011 (PAASC 2011)

The main goal of this Workshop is to bring together researchers, practitioners and industry representatives, providing them the opportunity to present recent research and development results, discuss lessons learned, and present novel ideas on topics in the area of performance assessment, business modeling and auditing in Service Oriented Architecture (SOA).

Call for Participation

Services represent a major part of the IT industry. In a Service Oriented Architecture (SOA), software resources are assembled as services. Several companies nowadays prefer to focus on their core areas and outsource certain services to attain their goals. Services computing leverages computing to model, create, and manage business services. Cloud computing has become a services delivery platform in the area of Services Computing, an increasing number of companies being attracted of the 'pay-as-yo-go' use of services. While extensive research is being pursued on technical aspects related to SOA (and cloud computing), business modeling and management in SOA, economic fundamentals of services, assessment in SOA and services/ SOA analytic modeling receive little attention. So far, relatively scarce research has been pursued on services/SOA analytic modeling, audit analysis and performance measurements. Although several benefits of service computing/ service oriented architecture are claimed, a generally accepted reference model, framework or analytical approach reflecting quantification of SOA economic benefits is not yet available. Several questions are still unanswered, such as:
How to quantify the economic benefits of SOA?
How to predict performance in SOA?
Which are the business models for SOA?
Which are the main decision criteria for service selection in services environments?
Which are the most relevant (economic) theories to support the formal definition and economic performance in SOA?
How can SOA be assessed?

This Workshop addresses broad issues on business modeling, auditing and performance assessment in SOA, aiming at gathering researchers and practitioners to exchange ideas, present and discuss their most recent achievements and lessons learned addressing these challenges related to business and performance assessment aspects in SOA.

The submission of papers describing research and development work on technical, business and economic related aspects on SOA is encouraged, e.g., new concepts and approaches related to business modeling and performance assessment, auditing techniques, tools and systems providing practical implementations supporting such models and approaches. In addition, we are also interested in application papers discussing the power and applicability of these methods and techniques to real-world problems. This Workshop encourages papers presenting novel research and developments, and particularly values the practical experience gained from designing, building and using services. Submissions of original and unpublished works are invited, including research, theory, and applications.

TOPICS of interested include, but are not limited to:
Business modeling in SOA (e.g., operational processes and policies, value configuration, technical cost modeling, formal modeling for core aspects on business in SOA)
Economics of service computing/ SOA (e.g., cost models, cost-benefit analysis)
Audit in SOA
Quality of services
Monitoring and evaluation of services/ SOA
Strategies and strategic decisions for services (e.g., concerning optimal resource utilization; service selection criteria)
Analytics of services
Methods, frameworks and methodologies synthesized for services' performance assessment (e.g., performance indicators, benchmarking methods, frameworks)
Self-management aspects for services (e.g., instant management of assigned resources)
Theories and approaches synthesized for services' representation and formal modeling, and their economics (e.g., transaction cost economics)
Performance predictability in SOA.

ICSOC Workshop papers will be available as a joint workshops post-proceedings in the Springer LNCS Services Science Subline.
