Introduction

When deployed as infrastructure components of real-time business processes, service computing applications upon which we rely for our daily activities elicit the proper addressing of performance and dependability issues. While recent developments in service-oriented architectures have come a long way in many aspects raging from semantics and ontologies to frameworks and design processes, performance and dependability remain a research demanding field. Nondeterministic dynamics of network environment and the diversity of resources and requirements pose challenges to state-of-art techniques aimed at meeting both functional and non-functional requirements of real-world service computing applications. This book is conceived under this perspective and aims at presenting the last achievements and future directions for research on performance and dependability in service computing

Book Objectives

This book is about service computing as a general concept, independently of standards or implementation platform. Naturally, current technological trends and related research issues shall be highlighted in dedicated chapters, but without restricting the scope. Indeed, editors are willing to receive papers present criticism on state-of-art technologies (e.g. Web Services) and exploratory essays on alternative approaches. Moreover, this book shall focus on performance and dependability, which are two complementary aspects including concerns of quality of service (QoS), real-time constraints, security, reliability and other important requirements when it comes to integrate services into real-world business processes and critical applications. Finally, the book is oriented towards state-of-art advancements and research challenges. The book is meant to serve as a guide leading the reader through the main concepts and technologies in service computing area as far as the next steps in research front and future directions.

Target Audience

The book is intended for an audience of researchers and engineers who are working in distributed computing, databases, and e-Business (primary application areas of service-oriented computing) and graduate students who wish to learn and spot the opportunities for their studies in this emerging research and development area. It will be of general interest to anyone using the service paradigms for software development, particularly on developing high performance and dependable applications.
