It is our great pleasure to welcome you to the 2nd International Workshop on the Quality of Service-Oriented Software System - QUASOSS'10 - affiliated with the 13th International Conference on Model Driven Engineering Languages and Systems (MoDELS 2010).
Our workshop provides a forum for both researchers and practitioners to discuss the open issues and emerging trends in the area of quality engineering for service-oriented software systems. Service-oriented software systems have recently emerged from component-based software engineering. They support a new paradigm, which is more aligned with business concepts and allows for dynamic composition of software architectures. Service-oriented software systems started as distributed or web-based applications, but are now spreading also into other domains (e.g., software-intensive systems). The paradigm of cloud computing with software-as-a-service applications is a recent representative of a new wave of service-oriented software systems. While concepts for service design, composition, provisioning, and management are currently maturing, a systematic engineering approach to service-oriented software with predictable quality-of-service (QoS) is still missing.
The program committee accepted 6 papers that cover a variety of topics, including performance modelling, performance measurements, trade-off analyses between quality attributes, and monitoring service-oriented system at runtime. In addition the program includes a panel on the future of quality engineering for service-oriented systems and a keynote speech by Dorina Petriu. We hope that these proceedings will serve as a valuable reference for researchers and developers.

Using quality of service bounds for effective multi-objective software architecture optimization
Quantitative prediction of non-functional properties, such as performance, reliability, and cost, of software architectures supports systematic software engineering. Even though there usually is a rough idea on bounds for quality of service, the exact ...
An integrated tool for trade-off analysis of quality-of-service attributes
In this paper, we present a tool for performing trade-off analysis of Quality-of-Service attributes of design solutions resulted from architectural, behavioral, or deployment changes in service-oriented systems. The tool allows for comparing the ...
Using software performance curves for dependable and cost-efficient service hosting
The upcoming business model of providing software as a service (SaaS) bears a lot of challenges to a service provider. On the one hand, service providers have to guarantee a certain quality of service (QoS) and ensure that they adhere to these ...
Performance-driven stepwise refinement of component-based architectures
Detailed models of component-based software architectures are crucial for the accurate evaluation and prediction of systems quality attributes (e.g., performance) during early development stages. Ideally, the increased complexity of such models should ...
Model-based dynamic QoS-driven service composition
As a consequence of their ever increasing pervasiveness in today's systems, software services are expected to guarantee their QoS even when operating in contexts whose operational conditions may continuously change. To cope with such continuous change, ...
Usage profile and platform independent automated validation of service behavior specifications
Assessing providable service levels based on model-driven prediction approaches requires valid service behavior specifications. Such specifications must be suitable for the requested usage profile and available hardware to make correct predictions and ...
