Architecture of Reliable Web Applications Software presents new concepts regarding the reliability, availability, manageability, performance, scalability, and secured-ability of applications, particularly the ones that run over the Web. Architecture of Reliable Web Applications Software examines the causes of failure in a Web-based information system development project, and indicates that to exploit the unprecedented opportunities offered by e-service applications, businesses and users alike need a highly available, reliable, and efficient telecommunication infrastructure. Architecture of Reliable Web Application Software proposes a scalable QoS-aware architecture for the management of QoS-aware Web services to provide QoS management support for both Web services providers and consumers. It also introduces Hyper-services as a unified application model for semantic Web frameworks and proposes Conceptual Model Driven Software Development as a means of easy adoption to them.
