“…The solution by Nascimento et al (2011), Abdeldjelil et al (2011, Chen and Romanovsky (2008) and Zheng and Lyu (2008,2010b,2010a allows the dynamic selection of variant services based on a priority schemes where the client defines requirements in terms of QoS. QoS values are updated by monitoring procedures in (Abdeldjelil et al 2012;Faci et al 2011;Nascimento et al 2011;Yuhui and Romanovsky 2008) and by encouraging users to contribute their individually-obtained QoS information of the target Web services in (Zheng and Lyu 2008,2010b,2010a.…”

“…The solutions by Gotze et al (2008), Townend et al (2005) supports execution of variants; however, they do not specify how variants might be executed in parallel, sequentially or both. Most solutions support both execution schemes (Abdeldjelil et al 2012;Buys et al 2011;Dillen et al 2012;Gonçalves and Rubira 2010;Gorbenko et al 2005;Laranjeiro and Vieira 2007;Mansour and Dillon 2011;Nascimento et al 2011;Nourani 2011;Yuhui and Romanovsky 2008;Zheng and Lyu 2008,2010b,2010a) the solution by Looker et al (2005), Santos et al (2005) and by Kotonya and Stephen (2010) support the parallel execution of variants. An important characteristic of the execution scheme proposed by Laranjeiro and Vieira (2007) is that it can use functionally equivalent web services that have different interfaces, providing developers with more options to build their solutions (i.e.…”

“…Consequently, SOA-based applications should operate according to their specification in spite of faults from reused services. If faults are not tolerated then undesirable consequences could happen, which may range from mildly annoying to great financial losses (Nascimento et al 2011;Zheng and Lyu 2010b).…”

“…These approaches operate as mediators between clients and variant services. The latter are structured in fault-tolerant composite web services (Nascimento et al 2011;Zheng and Lyu 2010b). Hereafter we refer to fault-tolerant composite web services as FT-compositions.…”

Background: Over recent years, software developers have been evaluating the benefits of both Service-Oriented Architecture (SOA) and software fault tolerance techniques based on design diversity. This is achieved by creating fault-tolerant composite services that leverage functionally-equivalent services. Three major design issues need to be considered while building software fault-tolerant architectures based on design diversity: (i) selection of variants; (ii) selection of an adjudication algorithm to choose one of the results; and (iii) execution of variants. In addition, applications based on SOA need to function effectively in a dynamic environment where it is necessary to postpone decisions until runtime. In this scenario, control is highly distributed and involves conflicting user requirements. We aim to support the software architect in the design of fault-tolerant compositions. Methods: Leveraging a taxonomy for fault-tolerant systems, this paper proposes guidelines to aid software architects in making key design decisions. The taxonomy is used as the basis for defining a set of guidelines to support the architect in making decisions related to fault tolerance in SOA. The same taxonomy is used in a systematic literature review of solutions for fault-tolerant composite services. The review investigates how existing approaches for fault-tolerant composite services address design diversity issues and also specific issues related to SOA. Results: The contribution of this work is twofold: (i) a set of guidelines for supporting the design of fault-tolerant SOA, based on a taxonomy for fault tolerance techniques; and (ii) a systematic literature review of existing solutions for designing fault-tolerant compositions using design diversity. Conclusion: Although existing solutions have made significant contributions to the development of fault-tolerant SOAs, there is a lack of approaches for fault-tolerant service composition that support strategies with diverse quality requirements and encompassing sophisticated context-aware capabilities. This paper discusses which 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.

Architecting resilient computing systems: A component-based approach for adaptive fault tolerance. Journal of Systems Architecture, Elsevier, 2017, 73, pp. ABSTRACTEvolution of systems during their operational life is mandatory and both updates and upgrades should not impair their dependability properties. Dependable systems must evolve to accommodate changes, such as new threats and undesirable events, application updates or variations in available resources. A system that remains dependable when facing changes is called resilient. In this paper, we present an innovative approach taking advantage of component-based software engineering technologies for tackling the on-line adaptation of fault tolerance mechanisms. We propose a development process that relies on two key factors: designing fault tolerance mechanisms for adaptation and leveraging a reflective component-based middleware enabling fine-grained control and modification of the software architecture at runtime. We thoroughly describe the methodology, the development of adaptive fault tolerance mechanisms and evaluate the approach in terms of performance and agility.

In this paper, we propose a technique for serviceoriented architectures (SOA) to dynamically evaluate the performance of Web services based on their previous history, and user requirements. The likelihood of fault occurrence is then used to create recovery plans. The 'best' recovery plan is then chosen to be either executed immediately, or saved for a later execution. We assess the overall system dependability using the generated plan and the available invocation information of the included services. Experiment results indicate the applicability of our technique, and show the improved performance in comparison with similar existing approaches.
