Failures during web service execution may depend on a wide variety of causes, such as network faults, server crashes, or application-related errors, such asunavailability of a requested web service, errors in the orchestration of choreography of applications, missing data or parameters in an execution °ow, or low Quality of Service (QoS). In this paper, we propose a healing architecture able to handle web service faults in a self-healing way, discussing infrastructural faults and web service and Web application faults. The self-healing architecture manages repair actions, such as substitution of a faulty service or duplication of overloaded services. Implemented prototypes involving QoS in coordinated web services are illustrated and discussed.
