College of Engineering | Seminar On: Monitoring and Adaptation of Composite web services

Title	Monitoring and Adaptation of Composite web services
Speaker	Dr Abdelkarim Erradi, Professor, Computer Science and Engineering Department ,Qatar University
Organizer	Department of Computer Science and Engineering
Abstract	Dynamic selection and composition of autonomous and physically distributed Web services is increasingly used to automate business processes. The typical long-running characteristic of business processes imposes new management challenges such as dynamic adaptation of running process instances to handle service failures and changes to quality of service parameters. The talk introduces MASC (Manageable and Adaptable Service Compositions), a policy-driven framework to declaratively express and handle crosscutting monitoring and process adaptation concerns in a separate and modular way. MASC policies govern: (1) discovery and selection of services to be used, (2) monitoring to detect the need for adaptation, (3) reconfiguration and adaptation of the process to handle special cases (e.g., context-dependant behavior) and recover from typical faults. The talk also discusses MASC middleware run-time mechanisms used to support adaptation during process execution such as optimizing service selection or reacting to a service failure. The talk concludes by discussing some open issues in the field and by sketching a possible research agenda.
