Abstract

Context: Over recent years, software developers have been evaluating the benefits of both Service-Oriented Architecture and software fault tolerance techniques based on design diversity by creating fault-tolerant composite services that leverage functionally equivalent services, or variant services. Three major design issues need to be considered while building software fault-tolerant architectures based on design diversity namely, selection and execution of variants and selection of an adjudication algorithm to determine the correct or adjudicated result from the variants. Each design issue, in turn, can be realized by a set of alternative design solutions, which present different degrees of quality requirements (e.g. memory consumption and reliability). Objective: To investigate whether existing approaches for fault-tolerant composite services support the above mentioned design issues and to provide a detailed classification of the analysed approaches. Method: A systematic literature review of diversity-based approaches for fault-tolerant composite services, which compose our primary studies. Results: We found 17 primary studies providing direct evidence about the research question. Our findings reveal that the primary studies support a wide variety of design decisions. For example, (i) variant services may be chosen at different points during the software lifecycle; (ii) both parallel and sequential execution schemes have been addressed; and (iii) a variety of adjudication mechanisms were found amongst the target papers. Conclusion: We build up a broad picture of what design issues have been addressed by existing diversity-based approaches for fault-tolerant composite services. Finally, practical issues and difficulties are summarized and directions for future work are suggested.
