Development of Dependable Web Services out of Undependable Web Components

Lookup NU author(s): Dr Anatoliy Gorbenko, Emeritus Professor Alexander Romanovsky



The aim of this work is to develop novel approaches to constructing and modelling dependable Web Services (WSs) built out of Web Components that can be undependable. To achieve this aim we have been working on the following tasks: - Analysing the WS failures modes and introducing a failure taxonomy; - Analysing Web security as an attribute of WS dependability; - Investigating a structured approach to the Web Service development that is based the Web Service Composition Actions (WSCA) scheme; - Proposing an event-driven simulation model of the Composite WSs; - Analysing the WS upgrading problem and developing schemes for WSs online upgrade; - Outlining future directions of WSCA-based systems development focusing specifically on the means for dependability achievement and assessment.
