Boshoff (1997) referred to service recovery as the component of quality management that can maintain the business relationship with customers. Tax and Brown (2000) defined service recovery as a process oriented towards the identification of service failure, resolution of customer’s problems, identification of root causes and improvement of the service system. Boshoff (2005a) noted that service ...

Chandra and Toueg introduced the concept of unreliable failure detectors. They showed how, by adding these detectors to an asynchronous system, it is possible to solve the Consensus problem. In this paper, we propose a new implementation of an Eventually Perfect failure detector (}P ). This implementation is a variant of heartbeat failure detector which is adaptable and can support scalable app...

In the future multi-cloud ecosystem, many cloud providers and consumers will interact to create, discover, negotiate and use software services. Cloud service brokers will play a central role in bringing providers and consumers together, assisting with software service creation (from abstract models to platform-specific deployments), multi-cloud translation (model-driven adaptation and deploymen...

A probabilistic methodology for evaluating failure risk, assessing service life, and establishing design parameters for structures subject to fatigue failure has been developed. In this methodology, engineering analysis is combined with experience from tests and service to quanti& failure risk. The methodology is particularly valuable when information on which to base design analysis or failure...

It is widely recognized that distributed systems would greatly benefit from the availability of a generic failure detection service. Such a service can however prove useful only if it can adapt simultaneously to changing network conditions and conflicting application requirements. This paper presents a novel approach to adaptive failure detectors, called φ-failure detectors, which dynamically a...

Service composition provides a flexible way to quickly enable new application functionalities in next generation networks. We focus on the scenario where next generation portal providers “compose” the component services of other providers. We have developed an architecture based on an overlay network of service clusters to provide failure-resilient composition of services across the wide-area I...
