“…We present a taxonomy of failures for web services. Our taxonomy results from the analysis of proposals in Chan et al (2007), Bruning et al (2007), Li et al (2014), Wang et al (2009), Fugini and Mussi (2006), Liu et al (2010) and Simmonds et al (2013). Similarly to Fugini and Mussi (2006) and Wang et al (2009), failures are classified into three main levels: service, composition and infrastructure.…”

“…This context may consider both the quality and the correctness of the service. Failures at this level are classified into content and timing (Wang et al, 2009;Chan et al, 2007;Fugini and Mussi, 2006;Li et al, 2014). Content violations are related to the definition and expected outputs of a web service.…”

We present an approach that improves the robustness of web service compositions enabling their recovery from failures that can happen at different execution times. We first present a taxonomy of failures as an overview of previous research works on the topic of fault recovery of service compositions. The resulting classification is used to propose our self-healing method for web service compositions. The proposed method, based on the refinement process of compositions, takes user preferences into account to generate the best possible recovering compositions. In order to validate our approach, we produced a prototype implementation capable of simulating and analysing different scenarios of faults. Our work introduces algorithms for generating synthetic compositions and web services. In this setting, the recovery time, the user preference degradation and the impact of different locations of failure are investigated under different strategies, namely local, partial or total recovery. These strategies represent different levels of intervention on the composition.

“…Some fault diagnosis and recovery approaches that analyse service composition are given in Anatoliy et al (2008), Fan et al (2010), Li et al (2014) and Yang and Susan (2011). In Anatoliy et al (2008), the authors present the results of error and fault injection into web services and analyse exception and performance as the major factors affecting fault tolerance.…”

“…A framework is proposed for handling fault of service composition through analysing fault requirements in Fan et al (2010). In Li et al (2014), the authors introduce a case-based reasoning approach to improve the system's fault-tolerant ability meeting the end-to-end quality-of-service QoS constraints. A recovery algorithm for service execution failure in the context of concurrent process execution are proposed in Yang and Susan (2011).…”

Service composition is an important means for integrating the individual web services to create new value added systems that can satisfy complex requirements. Such applications are subject to unexpected failure owing to the distributive and heterogeneous environment of web service. In this paper, we propose a Petri nets-based method to model and analyse the self-healing service composition. Aspect oriented programming is used to extract composition processes and self-healing strategy as the core and crosscutting concerns. A self-healing strategy of component and service composition is proposed, and the related operations of self-healing are abstracted as meta-objects by using reflection mechanism. Petri nets are used to construct the base layer model, meta layer model, meta-object protocol and other components, thus forming the self-healing model. The operational semantics and related theories of Petri nets help prove its effectiveness and correctness. A simulation example shows that our approach correctly describes the self-healing process of service composition, and contributes to improving the quality.
