The Application Interface Specification of the Service Availability Forum is a set of relatively new but well elaborated service specifications that facilitate the creation of highly available, fault tolerant applications. Even if not many, but there exist applications developed based on the specifications; however, a systematic way for creating those has not been published yet. This work describes a model-driven framework for the development of AIS based applications. It enables the creation and manipulation of the application models that are used for the generation of system configuration and component code skeletons, and which can be used for the automatic checking of correctness and various other non-functional requirements.
Using middleware implementations, instead of integrating the fault tolerance in the applications themselves, for providing stateful services highly availably has become the best practice in many industries including the telecommunication, computing and other areas. Robustness of these implementations toward user failures is essential for the overall availability of the systems. This paper summarizes the methodology for executing robustness tests on Service Availability Forum Application Interface Specification based middleware and describes the results of the conducted experiments with the OpenSAF open source middleware implementation. Finally, the results of the measurements/experiments are analyzed using the AMBER RAW Data Repository. robustness testing, high availability middleware, OLAP
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
