Towards an approach to sustain web services high-availability using communities of web services
Résumé
In any critical system, high-availability of software components like Web services has so far been achieved through replication. Three replication strategies known as active, passive, and hybrid, describe for example how many replicas are needed, where to locate replicas, and how replicas interact with the original Web service and among themselves if needed. The purpose of this paper is to show how replicates could be substituted with components that are similarly functional to the component that needs back-up in case of failure.
