Abstract
Service-oriented computing is a promising computing paradigm for software applications. However, there are a lot of key research issues in the service-oriented computing paradigm. Quality of Service (QoS) is a key factor to resolve these issues as well as a crucial aspect in the design of service-oriented systems as it directly touches the concerns of the service users. Therefore it is necessary and important to achieve a deeper understanding of different types of QoS properties. This chapter introduces three QoS properties namely performance, reliability and security, and provides an overview of these QoS properties and offer an in-depth analysis of the issues, challenges and research opportunities of QoS properties in designing and developing service-oriented systems.
