Automated runtime recovery for QoS-based service composition
Service composition uses existing service-based applications as components to achieve a
business goal. The composite service operates in a highly dynamic environment; hence, it
can fail at any time due to the failure of component services. Service composition languages
such as BPEL provide a compensation mechanism to rollback the error. But such a
compensation mechanism has several issues. For instance, it cannot guarantee the
functional properties of the composite service after compensation. In this work, we propose …
