Abstract:
Different mechanisms, such as checkpointing, task replication, alternative tasks execution or task migration among different resources, for instance, have been traditionally applied in (heterogeneous) grid environments for fault-tolerance. Cloud based resources can easily improve both availability and reliability of a given system when used for recovering faulty tasks. In this paper we present how cloud resources have been included in a framework for the execution of scientific workflows and how this has helped in improving the framework in two different aspects: making it more scalable and more reliable, facilitating the application of very effective fault recovery policies.
