An Integrated QoS-aware Service Development and Management Framework
Jiehan Zhou
Quality-aware service delivery has been receiving increasing attention in both software architecture and service management. Our approach values software and service quality assurance, ranging from quality assessment in software architecting to quality matching in service discovery. This paper proposes an integrated QoS-aware service management method, which examines the ‘service as a software’ development and the ‘software as a service’ management against QoS requirements. Moreover, we design an integrated QoS-aware service management infrastructure which promises complete software and service workflow management coupled with a QoS ontology development. We develop the QoS property ontology from the viewpoints of technical quality and managerial quality information management.
Flexible Software Development: From Software Architecture to Process
Dharini Balasubramaniam, Ron Morrison, R Mark Greenwood
Modern software development practices show that there is significant diversity in the product, process and geographical location of software development due to economical, technical and logistical constraints. Such diverse development demands flexibility in the software engineering methodology. In this paper, we propose the Cellular Development Methodology (CDM), an architecture-driven approach to flexible software development. CDM derives the development process and its architecture from the software architecture of product. The software development process is structured and customised as a network of cooperating cells. Our contribution is a cellular approach to software development based on the software architecture of the end product whereby a network of configurable cells yield customisable, potentially distributed software development processes which in turn produce software that is highly tailored to user requirements.
Adaptation and Distribution of Pipeline-Based Context-Aware Web Architectures
Michael Hinz, Stefan Pietschmann, Matthias Umbach, Klaus Meißner
The dynamic generation of context-aware applications for the ubiquitous Web is very time consuming and causes significant server load. Therefore, optimizing the efficiency of the publishing process and reducing server load by dynamically configuring system components are key factors for the commercial success of context-aware Web applications. To meet this challenge, this paper presents a framework that dynamically adjusts the architecture of pipeline-based context-aware Web systems either by adapting or omitting server tasks, distributing load within server clusters, or migrating load to client devices. The system adaptation and distribution are performed according to varying load rates and system context states that are monitored permanently. Furthermore, the paper also presents experiences gained by the implementation of prototypes and illustrates several useful application scenarios that are supported by the proposed mechanisms.
